3d Printing Fume Extraction
July 29, 2021

3D Printing Fume Extraction

Three-dimensional (3D) printing is an increasingly popular technique for prototyping and additive manufacturing. The  ever expanding number of applications for 3D printing technology means the industry is expected to increase from $0.7 Billion in 2019 to $5.6 Billion in 2026. 3D printing can use a variety of materials including plastic, resin, ceramics, wood, metal, graphite, nitinol, and paper. Due to the diversity of 3D printing applications, the scalable nature of 3D printing technology and the rapid growth of the industry, every 3D printing company is likely to hit a point where the need for fume extraction becomes apparent. Similar issues surrounding fugitive fumes caused by various production and fabrication processes exist in comparable industries like laser printing, laser etching and laser cutting to name a few. For the majority of these industries, there is an alarming lack of awareness and education revolving around the negative health impacts attributed to fugitive fume inhalation in the production phase. Even though 3D printing is a fairly new idea, fume extraction is not. For more than 20 years, Aeroex Technologies has been at the forefront of developing mist and fume extraction products for the industrial and commercial sectors. With decades of experience and expertise in air purification systems, the team at Aeroex was able to modify and improve on already highly efficient filtration technology to meet the specific needs of the 3D printing industry. 

Challenges of 3D and Laser Printing

With many institutional and DIY newcomers to the 3D printing realm, health and safety is becoming an increasingly discussed topic. To understand the health hazards associated with fugitive fume inhalation, we must first understand where the fumes come from. In the process of 3D printing, filament reels are melted by the printer as it moves along the pre-programmed path. While heating and melting the material, fumes are generated as a byproduct of the process. The composition of the fumes will depend on the material being printed. Some of the most common materials like thermoplastic polymers (e.g. ABS) are known to emit styrene, a suspected carcinogen that also causes headaches, drowsiness, and fatigue. Some materials can be substituted to reduce the toxicity levels of fumes, but this does not discount that fumes will be generated regardless of material. 3D printing often takes hours and even days to complete a project, with machines running for a long time to print each layer. 3D printing is an incredibly powerful and scalable technology, but output rates should not be limited by health and safety concerns and you should not have to downgrade your materials from durable thermoplastics to reduce the risk of these fumes. Instead, an air purification system designed for fume extraction in 3D printing will allow you to safely continue your prototyping or manufacturing work without compromise to productivity or health. 

Aeroex’s 3D Printing Strategy

Before proposing a solution for 3D printing fumes, the engineers at Aeroex spent considerable time researching  the nature of the fumes generated by 3D printing including the materials involved, equipment used, typical shop configurations, and the nature of the fumes released (composition and quantity). Much like our medical-grade air purification systems and/or mist extraction systems that are used  for other processes that generate fumes like CNC machining, we apply the principles of source capture  and ambient control. In the case of 3D printing, processes are usually quite modular and the sources of fumes are easy to pinpoint. Therefore,  the source capture method is bound to be highly efficient because fumes can be extracted before they enter the ambient conditions of your shop, which would require purification of much larger volumes of air at lower concentrations. Our attention to strategy and deployment planning is a key consideration when many other air purifiers cite the performance of MERV or HEPA filters without a plan for you to experience this level of performance.

The Right Filter for the Job

Beyond our overall strategy, the filters in question will ensure complete fume extraction during 3D printing or laser printing. For fumes like styrene which are associated with 3D printing, Aeroex uses activated carbon filters with a HEPA standard for particle size and efficiency. HEPA (also known as high-efficiency particulate absorbing, as defined by the US Department of Energy and the EPA), has an efficiency rating of 99.97% for particles as small as 0.3 μm. Typically, fumes exist in the particle range smaller than one micron, making the HEPA filter the optimal application for 3D printing. 

Commercial HEPA Air Filtration Systems with Activated Carbon

Activated carbon is a powerful technology that removes airborne gaseous chemicals through adsorption (adhesion of molecules to a surface without inducing solubility), which is why it’s a trusted part of sacred processes like the treatment of drinking water and wastewater. Activated carbon is also the focal point of Aeroex’s air purification systems design for fume extraction in 3D printing and laser printing. In an industry where claims about carbon are abound, Aeroex goes beyond the competition. We use real carbon made of coconut shells. While some companies will use small sprinkles of carbon in their filters so it can be cited in their product description, Aeroex goes as far as filling the filter media with small elongated pellets. During fume extraction, the air is pushed through the pellets to maximize the adsorption process, providing you with superior efficiency and long lasting filters.. The composition of our activated carbon and the sheer amount of it we use is a key reason to choose Aeroex, especially once you begin to understand the underlying “gold standard” technology of our products versus others who claim to provide fume extraction.

There are both established 3D printing practices in North America as well as quickly emerging companies that are still fine-tuning their processes. 3D printing companies are quickly realizing the need to focus on health and safety, but we would encourage you not to rush – instead take time to understand your fume sources and the purification technology. Some companies are offering “technologies” like bipolar ionizers, hydroxyl generators, and disinfectant foggers (as reported by outlets like Mother Jones and Colorado State University) that claim to be quick fixes, when in fact these will leave you at risk without the fume extraction you truly need. Due to the growth of 3D printing and the ever expanding variety of materials used for printing, the industry is still zeroing in on the best methods of industrial air filtration and ventilation, like our HEPA filters. 

We Are Committed to Supporting the 3D Printing Industry

We understand 3D printing is a growing industry, and we want to ensure the health and safety of your workplace for the long term. Our superior quality means the fume extraction technology you receive will be long-lasting and scalable as your 3D printing business grows, while the filters we use have large amounts of media that reduce the overall costs of filter replacements, by widening the maintenance intervals and lowering the labour hours required for maintenance.

Plastic Welding Fume Extraction
July 26, 2021

Plastic Welding Fume Extraction

Plastic welding is a popular technique for assembling goods from plastic components or materials because it allows you to directly join two compatible pieces without relying on adhesives or fasteners. This technique often produces products with a seamless appearance due to the components all being the same plastic material, without joints or clamps. The surface of the plastic is usually melted with a hot air welding gun. Although, there are other techniques like acoustic vibration, friction welding, laser welding, and contact welding. These manual techniques are useful for small operations, while larger operations can scale up with automatic welding. With these technologies, many of the goods we use in our everyday lives can be produced fairly inexpensively. However, any production technique that involves melting plastic will produce fumes that raise health and safety concerns and operational issues like accumulating by-products on the facility’s equipment. 

Challenges with Fumes in the Plastic Welding Industry

Plastic welding poses some unique challenges for air quality due to the types of materials being used and their operating conditions. Typically, rigid thermoplastics like PVC are welded at air temperatures of around 350 degrees Celsius to avoid discoloration or scorching of the product. Unfortunately, the melting point of these plastics and the operating temperature of the equipment mean that the emissions produced are bound to contaminate the ambient air in the facility.. The following are a few indicators  associated with industrial fume emissions: 

  • Acrylonitrile butadiene styrene (ABS) is known to produce black smoke and soot flakes.
  • Polyvinyl chloride (PVC) produces black smoke.
  • Acrylics produce a lot of odor.
  • Polycarbonate (PC) produces yellowish smoke and soot.

In each of these cases, fumes are producing chlorine, styrene, and other harmful by-products that cause acute effects like irritated skin or eyes, nausea, and headaches – with chronic effects including cancer. The rate at which these toxins are released can vary with your operating temperatures, complicating matters further. A plastic welding operation that wants to scale up has to manage these risks to remain safe and sustainable. 

As mentioned above, plastic welding smoke is often dark and mixed with fumes (the finer solid particles). Suspended in these emissions are large and fine airborne solid particles produced by vaporizing and condensing plastic particles, causing the dark color. The transient state of these particles means that they do not remain vaporized or airborne. The result? Condensation of smoke and fumes from plastic welding, leaving behind waxy residues! Setting aside the health and safety concerns of the fumes, these residues will impact and clog your machinery and conventional HVAC systems – driving up maintenance costs and reducing the useful life of your assets. The variation of particle sizes from smoke and fume combinations means that a uniform approach will not mitigate all emissions equally.

Strategies for Industrial Air Filtration and Ventilation

The waxy fumes and smoke from plastic welding are a reality of the production process that should be managed effectively for both safety and the longevity of your shop. This unique challenge is where Aeroex’s air purification systems perform as advertised while some competing air purification systems fall short as they advertise high efficiency, yet provide insufficient airflow to fully mitigate the inbound emissions. To manage waxy residues, a special design is needed to prevent clogging. Otherwise, you will be stuck doing perpetual maintenance without realizing the true benefits you should expect from your air purification system. 

Aeroex’s industrial air filtration units use progressive filtration technology where each stage is designed to complement the shortfalls of the last, and ultimately results in longer-lasting filters as well as allows filtration of particulate sized emissions and emissions on the molecular level. . Typically, this is where other air purification systems fall short and get clogged as these systems rely on the filter itself without primary mechanical elements. While these air purification systems “perform” well when brand new or during demos, they don’t have a design that will sustainably deliver the service you need. 

Since waxy emissions are a reality of plastic welding, then, there needs to be a way to deal with them in a way that does not impact your maintenance budget significantly. Your competitors are likely dealing with the same issue, due to the nature of plastic welding emissions. The progressive filtration approach allows the wax to accumulate on the primary washable elements, keeping your consumable activated carbon and HEPA filters in an environment where minimal wax residue is able to get through. The primary filtration elements are easily removable and hand-washable, a periodic and very low-cost maintenance activity. This design choice was intentional because it will prevent you from having the frequent filter replacement costs seen in other competitor models. 

Industrial Air Filtration Systems Designed for the Long Haul

Future-proofing your business is one of our core mandates, and Aeroex aims to outfit you with quality, made in Canada air purification systems. The longer your systems last, the better your investment return is, something Aeroex has strived for both in design and materials used. The nature of plastic welding is that it will incur costly maintenance to your filters if the correct design is not deployed. Aeroex has developed a solution that will cut through any issues you have had with clogged filters in the past. Our clients regularly report satisfaction at how durable our products are. For instance take Laker Energy, one of our first clients. Their mist collector (a similar product to what we would recommend for plastic welding) is going strong after 15 years, with the SAME FILTER inside – working smoothly after all this time. 

Our industrial air filtration systems will cut out the headaches of smoke and fumes during plastic welding, allowing you to focus on the things that matter like scaling up your business into automatic plastic welding. Contact Aeroex to talk to a specialist team member, get the specs, and plan an air purification deployment for your plastic welding operation today.

How Does Air Filtration Work
July 21, 2021

How Does Air Filtration Work?

With the identification of the novel coronavirus, we began to rethink the safety of our workplaces and what factors would need to be adjusted in the “new normal”. Within this context, the need to consider air filtration in the workplace became widely apparent. 

In 2020, it quickly became clear that many of the existing industrial air filtration systems were ill-equipped in their ability to adequately purify the air, notably in institutional facilities and other public workplaces like schools or offices. This finding demonstrated the need for greater investment in air purification. Despite this need, agencies are increasingly being asked to meet rising performance expectations while making greater use of limited funds. This means that the ideal air purification solutions that are needed can effectively mitigate risk, align with public health practices, and demonstrate investment performance. 

Medical Grade Air Purification

Aeroex understands the need for medical-grade air purification. We are experts in the science behind the process and have designed products to match. First and foremost, for medical grade applications, the main threat is biological matter (which is millions of times larger than the atmosphere’s molecules), therefore the filter efficiency should be very high, generally falling under the HEPA classification. However, this strategy does not help with small molecules such as VOCs. To tackle VOCs, one highly effective technique that is available involves a material called activated carbon. Understanding this, Aeroex uses multi-stage filtration processes that have compounding efficiency benefits in each stage, finishing with medical-grade HEPA filtration. 

Air purification needs to effectively improve the safety of the workplace in areas where there may be low ventilation or few options for physical distancing whereby in-room filtration is needed rather than products like UV lights which do not improve filtration. Aeroex products provide assurance and risk mitigation, and our understanding of the science behind medical-grade air filtration has allowed us to engineer state-of-the-art air purification systems used in public workspaces across North America. In-room air purification technology has been proven to significantly reduce the spread of COVID-19 by organizations like the WHO. Commercial HEPA Air Purifier filters should be used as an additional control measure to reduce the risk of exposure to COVID-19 – while they do not guarantee the complete elimination of a virus or replace any government recommendations, the performance they deliver will provide you with balanced risk management that keeps your facilities operational.

Aeroex IRIS Commercial HEPA Air Filtration Systems

If you operate a school, office building, or another public setting like a doctor or dentist’s office, Aeroex recommends the IRIS Medical Grade Air Purification Unit as a device that embodies the science of air purification and the practicality of your operation. It is specifically designed for occupied spaces that will protect your students and staff. Consequently, hundreds of our products can be found in school boards, colleges, and universities across Ontario, Canada.

IRIS Medical Grade Commercial HEPA Air Filtration Systems are equipped with a dual-stage, high-performance odour control MERV8/Carbon Primary filter and a 2nd stage HEPA filter with an efficiency rating of 99.97% @ 0.3 μm. Our exchange ratings use CDC guidelines to provide airborne risk mitigation through high-grade air purification. The IRIS series includes both portable and central purification systems and offers several secondary benefits like variable speed control and high-performance odor control.

Many cheap alternatives make big promises about the performance of their HEPA filters, but leave out key details about the capacity, air flow, and compatible room size for in-room air purification. This is a big issue that Aeroex is trying to combat – The effectiveness of an air purifier is usually reported in terms of efficiency, which can be misleading, as it only tells half of the story. The other crucial factor to consider is air flow. Together these two factors equal the Clean Air Delivery Rate (CADR), which is a better measure of how a device will perform. For example, 99.99% efficiency may sound great, but if the air flow is only 20 cubic ft./min. (cfm), one would be better off with a purifier at 90% efficiency and 50 cfm (CADR: ~20cfm VS. 45cfm). If the unit is incapable of providing sufficient air exchanges for the space it is located in, the efficiency rating is borderline meaningless.n. Make no mistake, Aeroex will deliver not just on the promise of long lasting HEPA filters but the availability of multiple models capable of an array of air flow ratings will make certain that a proper solution is matched to your needs.. For proof, check out our live demonstration of the IRIS-400 Medical Grade Air Filtration System in action versus smoke in an unventilated room for a visual depiction of how quickly we purify your workspace. We have successfully purified air for clients like schools, dentists, hospitals, and commercial offices.

Aeroex Emphasizes Safety, Quality, and Trust

By purchasing an in-room air purification system, you are putting trust in a company and a product that will keep your visitors safe. However, many companies are exploiting the circumstances of the past year to mislead customers and distribute dangerous products. As recently as May 2021, it has been uncovered that thousands of best-selling air purification devices purchased by schools with government grants are producing toxic chemicals and do not work as intended. As reported by Mother Jones, one of the United States’ top manufacturers (Global Plasma Solutions) is now facing a $750 Million lawsuit from the State of Delaware, charging that company claims were “deceptive” and made the air worse due to the ions it discharged. Be skeptical of companies like Global Plasma Solutions who make claims of advent “technologies” like bipolar ionization. 

Aeroex has an established history of producing air purification systems well before the COVID pandemic. Our investment in efficient designs and our decision to manufacture our products in Canada are part of our strong commitment to valuing the trust you place in us. We strive for longevity and wish to gain your confidence through demonstrated results from tried-and-true technologies. Aeroex is a company you can trust to provide in-room air purification for your school or meeting space.  

Lower Total Lifecycle Cost

The maintenance requirements for your purification system should also be scrutinized – products with cheaper prices often rely on badly designed filters that need to be replaced constantly. The same way a printer company wants to sell you ink cartridges, many air purification systems want you to keep coming back for costly filter replacements. If you are hoping to upgrade your facility with an air purification system funded by a grant opportunity or similar one-time funding, Aeroex products are likely the better solution because they have lower operating impacts on your business in future years. Competitors often use a fraction of the filter media used by Aeroex, resulting in competitor drops in efficacy within a few months of application and increased maintenance costs from high filter changing cycles. Aeroex wants you to get the best value for your investment.

Industrial Air Purification Systems

Industrial Air Purification Systems explained: learn the ins and outs of Aeroex Air Purification Solutions.

Industry powers the economic activity of our society, processing raw materials and manufacturing goods to create supply chains, jobs, and products. With advances in technology, our industrial processes have grown in complexity, scale, and capacity. The quality of the air in the workplace has been an issue dating back to the industrial revolution, but it is an issue that has evolved and persisted into our modern industries like metalworking and food production.

Industrial air quality concerns are more complicated than previously thought, including dust particles, mist, smoke, and fume issues – if these aren’t addressed with filtration, businesses could face occupational health and safety, production quality, equipment performance, and environmental compliance problems. Aeroex is at the forefront of the air quality challenges experienced by industry and the science behind keeping your workplace safe with clean air.

What Are The Industrial Air Quality Issues?

Air quality is threatened by a wide range of airborne pollutants. Poor quality is caused by contaminant particles, which can be big or small and in solid, liquid, or gaseous form. Common causes include smoke, mist, and fumes. The issues that you face will depend on your industrial process (ex. manufacturing, woodworking, food production, etc.) or if you are in a public setting (ex. schools or medical offices). To simplify the wide variety of pollutants that are fully addressed by Aeroex, the most common airborne pollutants in the industrial setting can generally be understood as smoke, mist, or fumes.

Smoke: Solid particulates released into the air as a byproduct of combustion. Particulates will vary in size and composition depending on the temperature of your combustion process and the medium being consumed (for example, diesel). Common sources include engines and generators. Many of the solid particulates vary

in size from those such as oil mist, meaning they can be captured at different stages of the same multi-step filtration process used in Aeroex air purification systems. Check out the ARO series products to see how we achieve this.

Mist: Mists are the liquid droplets of a substance or mixture that are suspended in the air. Their safety impacts vary greatly with the materials being used, their chemistry, and whether the mixing of chemicals is taking place. Mists are often issues in industries where water or liquids are used or where spraying takes place. Common use cases that Aeroex caters to include metalworking, laser cutting, spray painting, and food processing. Products like our Mist-Fit Series specialize in oil mist collection for industrial air quality purification.

Fumes: Volatilized solid particles such as iron or aluminum are released into the air, condensing and oxidizing to form dangerous fumes. If unmitigated, fumes can cause health issues including lung damage and cancer. Fumes are commonly associated with industrial processes like welding, textiles, painting, and paving. Aeroex could address these risks with an ambient air purification system (typically roof-mounted). This is suitable for any commercial or industrial setting.

Industrial air quality pollutants may appear complicated, but they can be easily addressed with industrial air purification systems designed by Aeroex and made right here in North America. We are at the forefront of air quality filtration technologies and are equipped to tackle the latest challenges like the need for medical-grade air purifiers.

What exactly is the distinction between an air cleaner and an air purifier?

Most of them think air cleaners and air purifiers are one and the same. However, there is a vast difference between the two.

Air cleaners filter the air and collect dust, especially the larger dust (mostly dead skin) and pet dander. Most air cleaners have a fan that, when turned on high, can produce a lot of noise pollution. An air cleaner is frequently evaluated using a CADR (clean air delivery rate) or the number of air exchanges per hour. CADR only tests for larger particles (pollen, dust, and particles larger than.3 microns in size) and not for viruses, mold, mildew, bacteria, VOCs, chemicals, or cigarette smoke. On top of this, replacement filters are expensive to purchase. The majority of people do not address the negative ion issue.

In contrast, air purifiers kill airborne pathogens that cause allergies and illness and operate quietly. Moreover, Air purifiers are less expensive to operate.

How Do Industrial Air Purification Systems Work?

Industrial air purification systems work by pulling the contaminated air from the indoor environment into a filtration system, passing the air through a series of mediums designed to efficiently remove all of the harmful particles before releasing it back into the work environment. For example, the ARO Series Mist Collectors uses four stages of filter media to target increasingly small contaminants with each stage. This is a simplification of a technical process that has been carefully designed by Aeroex engineers, who understand that separation is best accomplished in progressive filters of increasing efficiency that move from targeting larger particles to the smallest and most problematic. This general approach is always tailored and customized for what industrial air purification a user wishes to achieve. Solutions for contaminated air can be engineered to mitigate any industrial, commercial, or institutional contaminant, including oil mist, bacteria, dust, and other harmful particulates.

How do industrial air purification systems eliminate airborne contaminants and improve indoor air quality?

It depends on the vendor, as some will use older centrifugal technologies that don’t eliminate fine mist and require frequent after-filter replacements. In the case of Aeroex, we use filter technologies that pass the air through separating layers such as depth loading fiber, oil attracting mesh, HEPA filters that capture the smallest mist, smoke, and bacteria particles.

Ambient and Source Capture Methods

Industrial air purifiers are designed to provide filtration for smoke, mist, and harmful fumes. How you achieve this will depend on whether a source capture strategy or an ambient capture solution is the right installation for your facility.

Ambient solutions are a common approach regardless of your industry or process, and Aeroex clients may choose to mount an air purifier on the ceiling where it can be centrally situated. Like your existing air circulation systems, ambient capture continuously captures plant air, purifies it with the filter, and then circulates it back through your facility. Ambient capture will passively purify all the air in the room, meaning it is best suited for facilities where you do not have a discrete polluter and you wish to provide general protection. The disadvantage of this approach is that it may not be the most efficient approach if you can pinpoint a polluter source and use an air filtration system with an optimized location, in which case source capture will offer you more benefits.

Source capture filtration occurs by placing a mobile purifier at the site, or mounting it directly onto the emitter (Aeroex provides both types), to eliminate industrial pollutants directly at the source. Taking the time to understand the source of harmful contaminants will reduce your costs and improve health outcomes by designing for a more efficient and effective solution, which is why it’s always preferable to put controls on contaminants at the source.

Industrial Air Purification Systems in Action

Industrial air quality is an important determinant of the health of your workers, the performance of your equipment, and the success of your business. There is a wide range of issues depending on your industry that could include oil mist, food production by-products, smoke, or fumes, only a fraction of which are discussed above. The Aeroex series of products is ready to tackle all facilities, which is why Aeroex has completed 3610 projects in 51 industries.

Oil Mist Collection for Industrial Food Production

Take a Bite Out of Bad Air Quality with Oil Mist Collection for Industrial Food Production

Industrial food production is Canada’s second-largest manufacturing sector, accounting for 17% of manufacturing sales in Canada and 2% of total GDP. Not only that, but according to the Government of Canada, food production is only going up, with the industry growing at a rate of approximately 6% per year. When industrial food production rises to the scale and scope of Canada’s, environmental and workplace safety can become limiting factors due to the demands and emissions associated with industrial food systems. Aeroex is a manufacturer of industrial air purifiers experienced with industrial food operations that is ready to deploy the solutions needed for any emissions or assembly line issue.

A Healthy Diet of Food Industry Applications at Aeroex

Air quality and emissions issues vary significantly across a food production industry that includes meat products, beverages, bakery, grain/seed milling, animal feed, produce preservation, specialty products, dairy, seafood, and sugars. In Aeroex’s experience, the requirements for air purification or oil mist collection are very industry-specific. Each type of food production has different emissions, both as a function of the machinery being used, the design of the facility, and the types of products being applied during food production.

To increase the challenge, environmental and health and safety regulations place constraints on production and raise the need for mitigation measures. Aeroex has worked with several industrial food producers to solve these challenges and is ready to customize a solution that meets your needs. We outfit our air purifiers with oil extractors and have several accessories that modify our machines to meet your needs.

Pizza, Pie, and Bagels? Yum! Oil Mist and Smoke? Yuck! To appreciate our understanding of the many industry-specific needs for air purification during food production, consider a couple of examples:
1. Pizza

Whether you like a classic cheese and pepperoni pizza, vegetarian, or Hawaiian, we all love the smell of pizza once it comes out of the oven. However, industrial pizza production comes with its challenges. For example, consider the example of Dr. Oetker (founded in 1893 and established in Canada in 1960), famous for the Ristorante Pizza. When producing pizza, olive oil is used. Suction cups used in the process bring the pizzas to another production line, but the activity caused olive oil mist to be disseminated within the area. To mitigate risk to quality, equipment, and health issues at play, oil mist collectors were installed by Aeroex to align with the challenging steps of production involving olive oil mist.

2. Bagels

Montreal bagels are famous for their sourdough recipe combined with malt, eggs and honey to provide a distinct flavour. Even today, Montreal Bagels are often produced by hand and in-shop. The wood-fired ovens used to cook the bagels are a trademark and a source of big flavour, but also contribute to big environmental and health issues. When wood is burned at conventional cooking temperatures, the smoke presents a large number of health concerns including benzene, formaldehyde, acrolein, and polycyclic aromatic hydrocarbons. Inhalation causes respiratory problems and can be asthma triggering. Exposure can also lead to other occupational health issues include things like irritated eyes. Air purifiers like those produced by Aeroex are needed to keep the workplace (not to mention the community near an emissions source) safe and free of wood smoke so their bagels can be enjoyed in peace. Aeroex has proven experience with Fairmount Bagels that can attest to this.

3. Pies

Industrial food production for baked goods like pie often has challenges with oil mist on the production line, or for that matter any time those convenient tinfoil trays are in use. To give the customer the added convenience, most frozen or baked products have a “no stick” guarantee or feature. This means spraying the container with pressurized oil to line the baking sheet or crust tray. Oil mist issues here are common, as the oil applicator may not be perfectly directed at the target container. The concentration of the spray often means that fine oil spray mists get introduced into the broader environment of your production facility, causing unwanted health and safety issues or films forming on your equipment. Oil mist collectors are modular on the production line and will provide source control for oil mist, leaving you to rest easy and enjoy that perfect slice of pie.

What are mist collectors?

Mist collectors are industrial-grade machines designed to remove airborne particles from industrial working environments. While more commonly found in the metalworking industry, innovation in mist collector technology has also enabled their utility in other industrial applications including commercial food production, air purification, and other specialty uses. 

Businesses that rely on machining processes that emit harmful pollutants must ensure that the working conditions, including indoor air quality (IAQ), are compliant with contemporary exposure standards set by regulatory bodies like the Occupational Safety and Health Administration (OSHA), the National Institute for Occupational Safety and Health (NIOSH), American Conference of Governmental Industrial Hygienists (ACGIH) and Health Canada. For instance, OSHA limits exposure to 5 mg/m3 for all employees that work 8 hours/day and 40 hours/week, and any employer that does not comply with these restrictions could risk a lawsuit or fines. Health and safety committees work to achieve a recommended limit of 0.3-0.5 mg/m3 to provide a safe working environment. To be certain that your industry stays within the stated guidelines, an industrial hygienist should be consulted to determine the air quality in your environment. 

Luckily, Canadian-made Aeroex Technologies Inc. has engineered mist collectors for a large range of industrial applications in addition to metalworking, such as commercial food production, air purification, and other specialty uses that are compliant with the standards set by these regulatory bodies.

Where are mist collectors used?

Mist Collectors in the Metalworking Industry

Mist collectors used in the metalworking industry serve to trap harmful oil and coolant mist that is formed during machining processes. Oil and coolant mist exposure poses a significant health hazard risk to personnel and shop equipment. Regular and proper maintenance of metalworking machines can cut down on production time and aids in preventing machine failure. One way machine operators ensure proper maintenance of metalworking machines is by keeping their metal cutting tools lubricated. This keeps metals cool while in action, reduces friction, and protects their integrity in the long term. 

Amid machining processes such as milling or grinding, oil or coolant mist may be generated and can easily disperse throughout the work environment. When exposed to high temperatures, oil mist can develop into oil smoke in which the oil begins to burn before it is released into the air. This can pose a great health risk to machine operators and can contaminate CNC machine assets. Oil mist exposure can also leave behind a slick residue on the machines as well as the working environment. Slick working conditions can damage machines, as well as increase the risk of slips and falls occurring if not properly controlled.

Exposure to oil mist can occur through skin contact, breathing oil mist in, or ingesting it. People that are exposed to oil mist can experience symptoms such as irritation of the eyes or skin, a burning sensation in the mouth and throat, fever, rapid heart rate, shortness of breath, vomiting, and headache. Long-term exposure to oil mist can also increase the likelihood of developing skin and respiratory diseases, as well as cancer. With a growing shift in the industry toward the use of high-pressure coolant systems, many mist collectors on today’s market fall short in their ability to filter through the byproducts these coolants produce. 

Fortunately, Aeroex Mist Collectors are made to effectively remove byproducts that are produced by high-pressure oil and coolants used in metalworking processes to mitigate the risks associated with oil mist exposure. Aeroex Mist Collectors are built to be durable and low-maintenance to meet the everyday demands of your facility’s regular operations. Regardless of machine size, Aeroex Mist Collectors can be fitted to meet the needs of your equipment and can be customized with accessories that further ensure quality air filtration.

Mist Collectors in Commercial Food Production

Mist collectors can also be used in commercial food manufacturing processes to remove cooking odours, grease, smoke, and oil mist from food production facilities and commercial kitchens. Hygiene is essential when it comes to food and beverage processes – ensuring a sanitary work environment is imperative to reduce the risk associated with contamination necessary for quality. Moreover, clean working conditions allow your equipment to work at peak performance while also maintaining a safe work environment for employees. 

Requirements for businesses to meet air purification and oil collection standards in commercial food production will depend on a myriad of factors. Many businesses will seek professional advice when it comes to health, safety, and environmental standards concerning air purification and oil collection. Aeroex engineers offer years of experience in outfitting commercial food production facilities with air purification and oil collection solutions that meet the specificity of food production industry standards. Air purification systems can be equipped with Oil Extractors and other accessories needed to ensure your machines are fully capable of meeting everyday air filtration demands.

Mist Collectors in Speciality Applications

The modular nature of Aeroex Technologies air purification systems allows great flexibility when it comes to outfitting the needs of specialty filtration applications. Fume extraction in laser engraving, 3D printing, plastic welding, wet scrubber exhaust, mobile applications, odour and fume control, cold heading, stamping, heat treating, and parts washers applications can all be custom outfitted with Aeroex air purification solutions to control the release of undesired airborne particles such as mist, smoke, aerosols, fumes, odours, and exhaust. 

Mist collectors are vital for maintaining air quality standards in metalworking, commercial food production, as well as a myriad of specialty applications. It is no wonder why more and more businesses are seeking effective ventilation of unwanted airborne particles by opting for a mist collector machine that is compliant with industry air quality stands.

How Do Mist Collectors Work?

Many mist collectors work by using centrifugal technology where a rotating drum is used to intercept unwanted particles and merge into larger droplets that ultimately drain out of the unit. The disadvantage to centrifugal separation is its inability to separate fine mist particles. This is often supplemented with an afterfilter. The downside to relying on an afterfilter to eliminate fine mist particles is short filter life leading to diminished airflow. To maintain operational performance these mist collectors require frequent service with a high cost of consumables. 

The engineering experts at Aeroex Technologies Inc. have found a solution by using innovative filtration techniques and cutting-edge materials to ensure high-efficiency mist collectors that can maintain consistent airflow with industry-leading maintenance intervals. Aeroex mist collectors feature several innovative design elements that guarantee high efficiency, the extensive lifespan for its filters, and low operational costs. Design elements such as; first-stage mechanical element filters use inertial separation technology to drain up to 85% of contaminants from the airstream before entering consumable filters. Further filtration is achieved by using depth loading fiber bed filters to progressively capture the remaining mist particles, consolidate them to a central drain for return to the machine sump.  

Source Capture vs. Ambient Capture

In air filtration, source capture and ambient capture refer to where the air filtration takes place. As its name would suggest, source capture filtration occurs at the source where unwanted airborne particles are produced. In contrast, ambient capture works by continuously circulating plant air through overhead filtration units.

The main benefit of choosing a source capture mist collector is that it eliminates the mist directly at the source. This is a much more efficient and cost-effective solution. 

With ambient capture, the contaminants are allowed to exit the machine and circulate through the facility before it is captured by the ambient air cleaner. .. That’s why Aeroex designs machine-mounted mist collector solutions to effectively and efficiently capture air contamination at the source.

What Factors Should I Consider When Purchasing a Mist Collector?

Are you in the market for a mist collector for your unique application? Choosing a mist collector that meets your demanding day-to-day operations can feel overwhelming. However, meeting industry air quality standards and ensuring the safety of employees, equipment, and their working conditions should never be overlooked regardless of the industry you work in. The following, are guidelines that industries should look out for when purchasing a mist collector:

Air Quality Standards and Filtration Capability

  • The efficiency or MERV rating of filters indicates the specific size of particles in microns that can be collected by the mist collector. 
  • Delivered Airflow indicates the amount of airflow that a mist collector can intake factoring airflow loss with filters installed. Usually measured in cubic feet per minute (CFM).
  • Minimum particle size is measured in micrometers. Signified with the unit µm, they show the minimum diameter of aerosol that a mist collector is capable of filtering.

Air Purification requirements can be determined using our calculator.

Application, Size, and Weight Specifications

  • Consider what size mist collector you require to meet the needs of your industrial application. Use our calculator to help you determine which is the best unit for your specific needs. 
  • Size specifications indicate the dimensions of the mist collector unit. They are usually measured in feet (ft) and inches (in), and they go a long way in helping to determine the positioning and mounting opportunities available. 
  • The weight of the mist collector in pounds (lbs).

Sound Level Considerations

  • The sound levels of mist collectors are also indicated to show the amount of noise that it would generate while operational. This is measured in decibels (dBA). Top-of-the-line mist collectors aim to reduce noise levels as much as possible.

Power and Usage

  • Power specifications refer to the voltage requirements to power the mist collector and should be matched based on the power supply available at the facility.
  • Maintenance intervals will determine how frequently the filter must be cleaned or replaced.

Installation Options

  • Installation indicates how the mist collectors are to be mounted and connected for optimum performance. Generally, numerous mounting options will be available to accommodate the wide range of applications.

Air Purifier For Schools and other educational facilities.

Air quality has always been important, however, it’s never been more top of mind than now! The current global situation has compelled us to reconsider air quality, particularly indoor air quality in enclosed spaces such as educational facilities. Let’s talk about the importance of air purifiers at schools

Maintaining air quality in daycares, schools, colleges, and universities presents unique challenges. Essentially, they are densely populated spaces in which people tend to spend extended periods of time, thus increasing exposure for students and faculty to contaminated air that may be present.

It is not uncommon to find airborne particles such as dust, viruses, bacteria, allergens, and mold circulating in the air.

Air-Filtration-For-Schools---Air-Purification-For-Educational-Facilities---HEPA-Filtration---Aeroex-Iris---2.1

Our local schools should be clean and fit for learning. One way to reduce airborne contaminants and potential exposure to disease in classrooms and lecture halls are by using air purifiers. There are various options available, but essentially they all try to achieve the same result – clean air by neutralizing or filtering out contaminants.

What are Air Purifiers?

Air Purifiers are machines that either filter or neutralize airborne contaminants. They achieve this by employing various methods, but most can be classified in one of two ways: Filter driven air purification systems (such as HEPA air purifiers) or Needlepoint Bipolar Ionization, which neutralizes contaminants by ionizing the air.

What is a hepa air purifier?

HEPA filtration works by forcing air through a filter media, with numerous redirections in its path, causing 99.97% of microns smaller than 0.3 μm to be trapped. HEPA air purifiers are ideal for educational facilities as they are designed for use in occupied spaces, produce no byproducts, and can operate continuously with minimal maintenance.

Public Health Ontario has stated that “Air cleaners equipped with HEPA filters should be able to remove COVID-19 virus-sized particles from indoor air, which may contribute to a reduction in exposure to the virus.” (https://www.publichealthontario.ca/-/media/documents/ncov/ipac/2021/01/faq-covid-19-portable-air-cleaners.pdf?la=en)

Which hepa air purifier is the best for air filtration in Schools?

Aeroex has engineered the IRIS series of medical-grade HEPA Air Purification systems to tackle contaminated air in enclosed spaces. Ideal for applications in school classrooms, university and college lecture halls, medical waiting rooms, offices, and other high-traffic spaces. Aeroex air purifications systems are excellent for use in educational facilities as:

  • IRIS air purification systems come equipped with a 1st dual-stage MERV8 Carbon filter and 2nd stage HEPA filter with a rating of 99.97% at 0.3 microns.
  • Portable and central solutions are available.
  • Wall and ceiling mounts available.
  • Variable speed control is standard for many models allowing infinite adjustment to an ideal airflow and sound level.
  • Our units are classified by delivered airflow instead of rated airflow, making it easy to identify the suitable unit for a specific application. For example, the IRIS-400 delivers post filter airflow at the rate of 400 CFM.

Why You Need Hospital Grade Air Purifiers

Hospital grade air purifiers are effectively inconspicuous devices, and they purify the air in hospital waiting rooms, hallways, operating rooms, and wards. By so doing, they aid ventilation and reduce the spread of diseases from healthy people inhaling or contacting germs and other contaminants that are released into the air by the immuno-compromised or the sick.

Hospital grade air purifiers are very common in hospitals, and this is for a reason. Hospital air is known to contain a high concentration of contaminants and Volatile Organic Compounds (VOC), and with patients, doctors, visitors, other workers, etc., moving through the hallways, it has become a paramount necessity for hospitals to install hospital-grade air purifiers to reduce disease spread and other health implications that can be caused by these contaminants and VOCs.

Volatile Organic Compounds and Hospital Grade Air Purifiers

Volatile Organic Compounds are usually liquid materials that can change form and evaporate into the air. Since they are common hospital materials, they may seem like chemicals that are inherent to the atmosphere. However, a high concentration of these chemicals in a space with inadequate ventilation could lead to the creation of compounds like butane and other anesthetic gases. It is for the specific purpose of collecting these chemicals from the air and filtering them that hospital-grade air purifiers become important.

  • Examples of VOCs that are common to hospital environments are;
  • Alcohol: this is a liquid chemical used in hospitals as solvents and disinfectants,
  • Formaldehyde: this can be found in plastic and lacquers,
  • Acetone: this chemical can be found in furniture polish, and wall paint,
  • Ethanol: This chemical is used in cleaning glass containers, and in hospitals, it is found in cleaning solvents and detergents,
  • Dichloromethane: this is found in aerosol and paint removers.

Places in the hospital where air purifiers should be Installed

Hospital Wards
Hospital wards can be contaminated with viruses and bacteria that could cause an asthmatic reaction. Depending on the equipment installed in the wards, and the types of gasses they emit, there could be events where they contain fumes and some amounts of carbon dioxide. With the risks of transmission of disease and contamination, hospital wards must have hospital-grade air purifiers installed. These wards include burn units, hospital wards, pediatrics, geriatrics, TB isolation wards, etc. Having a hospital-grade air purifier improves hospital ventilation and ensures that the hospital facility maintains a clean atmosphere with untainted airflow. These devices can also protect respiratory health by removing contaminants in form of mold spores before they get inhaled by patients.

Operating Theatres and ICU
A study of hospitals in China found a reduction in healthcare infections in hospitals where air purifiers were being used.[1] Patients coming out of surgery are usually at a high risk of infection from particles flying around the operating theatre or the ICU. However, with hospital-grade air purifiers installed and the air purified of all contaminants, it would become less likely for them to be reduced as the study cited above shows.

Hallways and Waiting rooms
It is typically demanded that at least 20% of hospital air should be fresh air from outside. However, this fresh air could contain germs and contaminants. Considering these risks, it is therefore important to install hospital-grade air purifiers in corridors and waiting rooms are essential for ridding the atmosphere of these contaminants before they get inhaled by patients and cause further health complications.

Sick Building Syndrome

Hospital grade air purifier devices are also useful in preventing what is known as Sick building syndrome (SBS.) Sick building syndrome is usually a result of poor ventilation and poor indoor air quality. As such, the syndrome and can be prevented by installing the right hospital-grade air purifier to remove viruses, bacteria, enzymes, and other particles from the air, and improving indoor air quality that may be tainted by the exhaust, moisture, and concentration of harmful chemicals.

Categories of Hospital Grade Air Purifiers

Hospital-grade air purifiers can be categorized by size as well as the budget of the person trying to purchase them. When buying hospital-grade air purifiers, factors like the space available for accommodating the devices, and the funds available for the purchase should be considered. Below are the several categories of Hospital-grade air purifiers that we have.

Budget-friendly
This air filter is very portable and easy to install. It is often hung on walls in hallways, waiting rooms, and wards. As the name suggests it is also budget-friendly and it is suitable for hospitals that have an HVAC system already installed.

Middle-priced
These categories of air filters are larger than their budget-friendly counterparts and are also more quality. These air filter makes use of HEPA filters and allows for quite effective airflow. It uses activated carbon and zeolite in removing fumes, gases, and odors from over 700 feet of its environment. The middle-priced air purifier also runs silently, and with its build, it retains the capacity to trap more particles.

Step-Up Price
These hospital grade air purifiers take the cake in terms of quality and can purify the air of rooms with an area over 1000 square feet. They are the largest purifiers one can find, and they are the most suitable large wards or hospital halls. Equipped with HEPA filters, they are also capable of filtering the finest particles, and step-up filters are best installed in hospital wards that hold patients suffering from asthma or allergies.

What is HEPA filtration?

HEPA stands for high-efficiency particulate air. HEPA filters are mechanical filters that work by pushing collected air through a mesh while trapping fine particles, fumes, and smoke. The most effective air purifiers are determined by their ability to filter the finest particles, and as discovered by a NASA study[2], HEPA filtration is capable of filtering particles that measure down to 0.01 microns, making it the most effective yet known with most viruses and particles measuring between 0.06 – 0.14 microns, the most effective hospital-grade air purifiers should be equipped with HEPA filters.
