Environmental regulations have become increasingly stringent in recent years as governments and regulatory bodies recognize the importance of protecting our planet’s natural resources and ensuring a more sustainable future. One area of focus in these regulations is air quality. Companies are now required to comply with regulations related to air pollution and other environmental factors, and failing to do so can result in significant consequences. 

One important aspect of compliance with these regulations is in employing the use of mist collectors. Mist collectors are devices used in industrial settings to remove mist and particulate matter from the air, improving air quality and helping companies meet environmental regulations. 

In this blog post, we will explore the role of mist collectors in compliance with environmental regulations.

The Importance of Complying with Environmental Regulations

Compliance with environmental regulations is important for protecting the planet and ensuring a sustainable future in the long term and preserving the health and safety of your workplace environment. These regulations are designed to limit pollution and other harmful practices that can have negative impacts on the environment and human health. 

Non-compliance can result in significant consequences for businesses, including fines, legal action, and damage to a company’s reputation. Complying with these regulations can lead to improved air quality, reduced waste and energy use, and a healthier work environment.

It is the responsibility of companies to prioritize compliance with environmental regulations, not only for the benefit of the planet but also for the long-term success of their business.

The Role of Mist Collectors in Environmental Compliance  

Mist collection systems play a critical role in helping companies comply with environmental regulations related to air pollution, as they can significantly reduce the number of harmful particles and chemicals released into the atmosphere. 

These systems are engineered to capture mist, smoke, and other airborne particulates that are generated during manufacturing processes in a variety of industries, including metalworking, woodworking, and food processing.

This is important because many of these pollutants, such as oil and coolant mist, can have serious health and environmental impacts. When inhaled, oil mist can cause respiratory problems and other health issues. 

Mist collectors work by using a series of filters and centrifugal force to separate the mist from the air. By capturing these pollutants before they are released into the air, mist collectors help to ensure that industries meet the strict environmental regulations set by regulatory bodies.

Mist collection systems also offer economic benefits for industries. By reducing the number of pollutants released into the environment, industries can avoid costly fines and penalties associated with non-compliance with environmental regulations. Mist collectors can help to improve the overall efficiency of manufacturing processes by improving air quality for workers.

Environmental Regulations Related to Air Pollution

Canada Regulations

Each province and territory in Canada has its environmental regulations related to air pollution, in addition to federal regulations. These regulations may be more stringent than federal regulations. Companies that use mist collectors must be aware of any provincial or territorial regulations that apply to their operations.

The Canadian Environmental Protection Act (CEPA) is a federal law that regulates substances that may have an impact on human health and the environment. The law authorizes the regulation of emissions of toxic substances into the environment, including indoor air quality. Companies that use mist collectors may be subject to CEPA regulations, depending on the type of pollutants they generate.

The National Pollutant Release Inventory (NPRI) is Canada’s national inventory of pollutant releases and transfers. The inventory requires companies to report on their releases and transfers of over 300 substances, including air pollutants. Companies that use mist collectors may be required to report their emissions of pollutants such as volatile organic compounds (VOCs) and particulate matter.

Industrial Emission Performance Standards (EPS) are performance standards that have been established for various industrial sectors in Canada. The standards set emission limits for air pollutants based on the type of facility and the production process used. Companies that use mist collectors must comply with the EPS for their sector.

Environmental standards are regulated both federally and provincially. Each province will have further provincial regulations it must comply with – for example, the province of Ontario has regulations including the Environmental Protection Act and the Clean Water Act. These regulations will complement those at the federal level, typically prescribing with greater detail in areas of provincial jurisdiction. 

USA Regulations 

One of the most significant environmental regulations related to air pollution is the Clean Air Act (CAA). This federal law regulates air emissions from stationary and mobile sources. The Environmental Protection Agency (EPA) has the authority to establish national ambient air quality standards and regulate emissions of hazardous air pollutants. Companies in industries like manufacturing, metalworking, and woodworking may be subject to a range of CAA regulations, depending on the type of pollutants they generate and the size of their operation.

Another set of EPA regulations is the National Emission Standards for Hazardous Air Pollutants (NESHAP). It establishes emission standards for specific hazardous air pollutants. 

Companies that are installing new mist collectors or upgrading existing ones may need to comply with the New Source Performance Standards (NSPS). These are EPA regulations that establish emission standards for new or modified stationary sources of air pollutants.

In addition to federal regulations, many states and localities have regulations related to air pollution. Companies that use mist collectors must be aware of any state or local regulations that apply to their operations.

Industrial Air Purification Advancements

The topic of industrial air purification has grown in popularity in recent years, as more and more people become aware of the negative impact of air pollution on health and the environment, and the benefits air purification brings to manufacturing processes. Luckily, technological advancements have led to the development of more efficient and effective air purification systems for industrial settings. 

In this blog post, we will explore the future of industrial air purification, including recent advancements and innovations in technology including Electrostatic Precipitators, UVGI Air Purifiers, and High-efficiency Particulate Air Filters (HEPA). 

The Role of Industrial Air Purification in Dealing with Industrial Air Pollution 

Industrial air pollution refers to the release of harmful substances, such as gases, particulate matter, and volatile organic compounds (VOCs), into the air from manufacturing and industrial processes. Exposure to air pollution can cause respiratory problems, cardiovascular disease, and even cancer. This is why air purification is essential in industrial settings, where pollutants are often released into the air during manufacturing and other processes.

Air purification systems have become increasingly important in industrial settings to mitigate the negative impact of industrial air pollution. These systems help to remove pollutants from the air, providing cleaner and healthier air for workers, your specialty equipment, and the surrounding community.

Advancements in Industrial Air Purification Technology

Electrostatic Precipitators

Electrostatic precipitators (ESPs) are effective at removing particles from the air, including those that are too small to be captured by other types of filters. They work by using an electrical charge to ionize particles in the air, which are then attracted to oppositely charged surfaces, such as plates or wires. As the particles build up on these surfaces, they are periodically removed by mechanical means, such as shaking or washing.

Electrostatic precipitators are a proven and effective technology for air purification, particularly in industrial settings where large amounts of pollutants are produced. However, they can be expensive to install and operate, and may not be effective at removing certain pollutants such as gases. As with any air purification technology, it is important to properly maintain and operate ESPs to ensure their effectiveness over time. While ESPs don’t require filter replacements, the plates need to be cleaned to maintain the electrical charge. Working with electricity is also a safety concern not posed by conventional filtration. ESPs are expected to continue as a specialty application where electrochemistry adds efficiency over other methods.

UVGI Air Purifiers

UVGI (Ultraviolet Germicidal Irradiation) air purifiers use ultraviolet light to kill microorganisms such as bacteria, viruses, and mold that can be found in the air. When the air passes through the purifier, it is exposed to a UV-C lamp that emits short-wavelength ultraviolet radiation. This radiation is absorbed by the microorganisms in the air, damaging their DNA and rendering them unable to reproduce or cause harm.

UVGI air purifiers are very effective at killing microorganisms and preventing the spread of infectious diseases. This makes them essential in healthcare settings, where airborne pathogens can be a serious concern. UVGI air purifiers also have some limitations. They are generally less effective at removing larger particles, such as dust and pollen, from the air. 

UVGI air purifiers are a promising technology for air purification, particularly in healthcare settings where preventing the spread of infectious diseases is critical. However, they should be used in conjunction with other air purification technologies to ensure that all types of pollutants are effectively removed from the air.

UVGI is still an emerging technology, and the results have been mixed – there are genuine UVGI applications, as well as products that did not deliver the intended results notably during the early stages of the global pandemic. There are also tradeoffs with conventional methods of air purification in healthcare settings, notably the use of high-efficiency particulate air filters (HEPA). 

High-efficiency Particulate Air Filters (HEPA)

High-efficiency particulate air (HEPA) filters are a type of air filter that is designed to remove small particles from the air, including dust, pollen, and other airborne pollutants. HEPA filters work by forcing air through a dense mesh of fibres that trap particles as they pass through.

HEPA filters are highly effective at removing particles from the air, with some models capable of removing up to 99.97% of particles as small as 0.3 microns in size. This makes them particularly useful for people with allergies or respiratory issues, as they can help reduce the number of airborne allergens and irritants in the air.

HEPA filters are widely utilized in various industrial settings, particularly in controlled environments like cleanrooms. They can effectively eliminate airborne contaminants and prevent the spread of pollutants, which is of utmost importance in workspaces where people handle hazardous materials or in areas where hygiene and sanitation are paramount.

Overall, HEPA filters are a highly effective air purification technology that can help remove small particles from the air. They are particularly useful in industrial settings where air quality is critical, as well as for people with allergies or respiratory issues. However, they should be used in conjunction with other air purification technologies to ensure that all types of pollutants are effectively removed from the air.

Aeroex continues to leverage the HEPA technology to eliminate airborne contaminants like coronavirus in public/institutional settings like schools or even in clean rooms with heightened regulatory requirements (e.g. pharmaceutical manufacturing).

The Best CNC Mist Collector Based on Your Needs

CNC machining has revolutionized the manufacturing industry by enabling high precision, accuracy, and efficiency in producing complex parts. However, the CNC machining process generates mist, smoke, and other airborne pollutants that can harm human health, damage machines, and affect the quality of the finished product. Therefore, a CNC mist collector is essential to remove these pollutants and improve the working environment.

In this blog post, we will explore how to choose the best CNC mist collector for you based on your unique business needs. We will also provide an overview of the factors to consider when selecting a CNC mist collector, such as the type of CNC machine, size, performance efficiency, filter capacity, noise level, and cost. Read on to learn more.

Factors to Consider when Choosing the Best CNC Mist Collector

Type of CNC machine

The type of CNC machine you are using is one of the most important factors to consider when choosing the right mist collector. As different types of CNC machines produce varying amounts of mist and smoke, you should choose a mist collector that is designed to handle the pollutants generated by your machine.

For instance, lathes and milling machines generate a lot of oil mist, which requires a mist collector that can efficiently separate oil from the air. On the other hand, laser cutters and plasma cutters generate more smoke and fumes, which require a collector that can effectively filter out fine particles.

Size of the CNC machine

The size of your CNC machine is another important factor to consider when choosing the right mist collector. The size of your machine will affect the amount of mist and smoke that is generated during the machining process, and this will impact the size and capacity of the mist collector that is needed to effectively capture and remove pollutants.

If you have a small CNC machine, such as a tabletop mill or lathe, you may only need a small mist collector that can fit on the machine or on a nearby surface. If you have a large industrial CNC machine, such as a machining center or plasma cutter, you may need a larger mist collector that can handle a higher volume of pollutants.

Performance Efficiency

Performance efficiency is another factor to consider when looking for the best CNC mist collector. The performance of a mist collector can be evaluated based on its ability to remove mist and smoke from the air, as well as its energy consumption, noise level, and maintenance requirements.

The efficiency of a mist collector is typically measured in terms of its capture efficiency, which is the percentage of mist and smoke particles that are captured and removed from the air. Capture efficiency can vary depending on the type of mist collector and the size and composition of the particles being captured.

Filter Capacity

Filter capacity is an essential factor to consider when choosing the best CNC mist collector. The filter capacity of a mist collector determines how much mist and smoke particles it can capture before the filter needs to be replaced. The filter capacity of a mist collector can vary depending on the size and type of the filter and the application of the CNC machine.

It’s also important to consider the type of filter used in the mist collector. Some filters are washable and reusable, while others are disposable and must be replaced after a certain number of hours of use. Washable filters can save money on replacement costs, but they require more maintenance to clean and dry properly. Disposable filters may be more convenient, but they can result in higher ongoing maintenance costs.

Noise Level

When evaluating noise levels, consider the decibel (dB) rating of the mist collector. Look for mist collectors with low dB ratings, preferably below 70dB, as these tend to produce less noise and are generally considered more suitable for indoor use. A mist collector with a low noise level rating can help reduce noise pollution in the workspace and create a more comfortable working environment for machine operators and other employees.


While cost is an important consideration, it’s also essential to remember that cheaper mist collectors may not always provide the best value in the long run.

When evaluating the cost of a mist collector, consider the upfront purchase price as well as ongoing maintenance costs. Cheaper mist collectors may require more frequent filter replacements, leading to higher ongoing maintenance costs. Conversely, a more expensive mist collector may have a higher upfront cost but may require fewer filter replacements, resulting in lower ongoing maintenance costs.

Mist Collectors

Location of Mist Collectors

Location of Mist Collectors

The design, filtration size, and air handling capacity of industrial filtration systems like oil and coolant mist collectors are often discussed for their impacts on air quality. However, the location of the oil mist collector is an overlooked but critical aspect of your air filtration strategy. The location of the mist collector is a key consideration for any deployment made by Aeroex. By ensuring the proper placement and integration of the mist collector, the right capture strategy can be used that provides optimal efficiency. 

Types of Locations for Mist Collectors

There are two general ways of locating your coolant and mist collector. You directly integrate the filtration system with your machine to provide source control as a closed system, or you can install it nearby on the wall or ceiling (often paired with your existing ventilation) to provide ambient control. Each provides benefits and rationale, although for machining operations Aeroex recommends starting with source control first. 

Location of Mist Collectors for Source Control

Source control means capturing contaminant air particles directly at the source of release by maintaining close proximity and a direct feed between the source and the method of filtration. The advantage of this technique is that the duration between release and capture is limited, there are fewer opportunities to enter the atmosphere, and a higher concentration of particles can be captured before they begin to diffuse. A source control solution is highly efficient as a result – a higher concentration means less air is circulated through the filter for the same amount of particles captured. However, a source control solution can be more demanding for the air filtration system. If it cannot efficiently remove the large number of particles, you may get a buildup or disruptions like clogging. 

Aeroex systems are designed for source control locations first and foremost, with depth loading filters, screening methods to optimize filter efficiency, good drainage, and large volumes of filter media. This is the most efficient way to target oil and collant mists that come from a discrete source. In machine shops, oils and coolants are usually sprayed within an enclosure, making them opportune for a source control strategy. 

Location of Mist Collectors for Ambient Control

If an ambient control strategy is being used, typically the filtration system will be installed on the ceiling or with an existing ventilation system to oversee a broader area or a series of operations and sources. Normally, an ambient strategy is only recommended when a contaminant source is not discrete or there are too many sources for a source control strategy to be feasible. Some machine operations like grinding also pose source control challenges. Ambient control can also complement source control – for example, if you had several grinders equipped with source control measures you may also use ambient control as the finishing method to eliminate any remaining contaminants.  

An ambient control solution applies to the entire room of a facility, meaning it will need to circulate more air than a source control method to replace contaminants with clean air. This is due to the effects of dispersion. As well, the lower circulation frequency compared to source control (enclosures can often be cycled in seconds) mean that there is the potential for interim exposure in the atmosphere. 

While source control is most common for machine operations, ambient control is common in other applications like healthcare and institutional settings.

Mounting Oil Mist Collector for Source Control Strategy

Aeroex is committed to the source control strategy, so much so that we have created a wide range of mounting options to ensure that whatever the circumstance, models like our Mist Fit can integrate into your shop. Where other suppliers may opt for a less efficient strategy due to accessibility issues, we will go to extra lengths to ensure a source control strategy is feasible. We understand space is a scarce commodity in any machine shop, and mounting to a machine can therefore require some creativity. Our install kit provides mounting options by including custom and prefabricated base plates, flanges, base plates with side suction, side mounts, elevated base plates, side mount extensions, pillar stands, wall mounts, and more.

How to Choose the Location of Mist Collectors

When choosing the location of your mist collector, we will assess the footprint of your facility, the existing ventilation, the location of your machines, conflicts with other devices and utilities, routing, accessibility, and other factors. From there, we will assess the options for a source control strategy. Often this is straightforward but if not the Aeroex team will get creative in providing you with a safe and optimal location solution. In almost all cases, source control is achieved.

Improving Air Quality for Schools

Fan Filter Units To Improve Indoor Air Quality of Schools and Other Public Buildings 

Schools and other public institutions like hospitals are among the critical infrastructure that delivers services we all depend on. The ability to access and leverage these services depends on properly functioning infrastructure like structural, electrical, and mechanical building elements, all of which require funding and maintenance to operate. This includes the mechanical ventilation and heating/cooling systems in schools and other public buildings. Without proper ventilation, several undesirable air quality indicators can arise including stale air from low oxygen, the air being too hot or too damp, the accumulation of pollutants, and the presence of airborne bacteria and viruses including coronaviruses.

The State of School Ventilation Systems

A common trend among Canadian schools and other similar jurisdictions is a growing backlog of maintenance leading to poor performing infrastructure and ventilation. For example in Ontario, it was reported that 28% of schools and 45% of hospital assets are not in a state of good repair. The backlog of maintenance for schools alone would cost $3.7 billion in 2020 dollars. This figure includes a significant amount of mechanical ventilation systems.

If you think back to a Canadian school you attended as a child, this experience probably resonates with you. You likely attended a post-WW2 school with older infrastructure that is now aging and was always too hot and stuffy or too cold – many of these schools don’t even have air conditioning. With budget shortfalls every year and an aging portfolio, ventilation systems are getting worse all the time and reinvestment by the government is barely keeping up.

Impacts of the COVID-19 Pandemic

There was a growing awareness of ventilation issues in schools and some incremental investments to mitigate the issue prior to the pandemic, but everything changed during the global pandemic of 2020. When it was discovered that COVID-19 was airborne and could be mitigated by proper ventilation and air purification, there was suddenly a great interest in improving the indoor air quality of schools.

Governments are now aggressively trying to tackle the ventilation problems in schools that have been growing for decades. Everyone wants to keep kids safe and schools open, meaning that if investments in ventilation can improve this outcome then there is a strong case to do so. But the scale of the problem, the urgency of the situation, and the competing interests for limited funds challenge this goal. Therefore, there is a clear need for affordable and scalable solutions that can immediately improve the air quality of schools.

Challenges with HVAC Retrofits

Given schools already have an HVAC system, retrofits to improve air exchanges and provide more filtration are a common approach. This is often borne out of a desire to avoid a full system replacement, which is costly and disruptive for schools with classes in session. However, retrofits have their own challenges and may not bring the desired outcomes.

First is the matter of filtration – HEPA filters are widely accepted as a gold standard for capturing particles transmitting coronaviruses, and there are already encouraging investments by governments in deploying them. However, HEPA filters are often being used to augment the retrofit or overhaul of existing ventilation systems. This is where problems can arise, as old ventilation systems typically were not designed to incorporate a HEPA filter. This leads to significantly higher costs for schools with limited funds.

Second is the matter of air handling capacity. To move the air through HEPA filters retrofitted to the existing ventilation system, air handling also needs to be increased. Blowers usually need to be replaced in order to generate enough cubic feet per minute and static pressure to move air through the HEPA filters. This then expands the scope of the ventilation upgrade and adds cost. Adding capacity can be a complicated process because of the integrated nature of mechanical ventilation – if done incorrectly, not all rooms get the needed airflow. Therefore, a more cost-effective and practical solution for schools is desired.

Portable Air Purifiers for Indoor Air Purification

Some may ask, why not just use the portable air purifiers commonly seen in school classrooms already? Portable air purifiers are an important part of the toolkit because they are easily deployed, are affordable, and can be moved between areas. They were popular early in the pandemic because of the need for a quick solution.

Aeroex provides portable air purifiers and continues to advocate for their importance. But in a situation like schools where a permanent solution is desired and there is a backlog of ventilation repairs, portable air purifiers don’t address some of the root causes or provide the desired level of service. Portable units have more opportunity for human error, and they sometimes get turned off by the user because of the background noise they make when compared to traditional ventilation. Ambient control measures in the ventilation system are near the ceiling where they are less disruptive and become a permanent fixture providing constant air circulation and filtration.

Fan Filter Units – High Capacity and Cost Effective Air Filtration

To solve the problem of costly retrofits to a backlog of mechanical ventilation systems in schools with an immediate need for air filtration brought on by a public health challenge, Aeroex proposes the use of fan filter units.

Fan filter units equipped with HEPA filter units provide both additional air circulation and air filtration thanks to the high performance filters. Typically a fan filter unit is installed in the ceiling but it can act as a standalone unit, rather than completely retrofitting an existing system. A fan filter unit will easily integrate into the conduits of existing utilities in a school. The ease of installation and the comparable performance to upgraded ventilation with filter retrofits make fan filter units the clear choice. A fan filter unit will give the same result for less money! 

The AIR FIT Fan Filter Unit

Fan filter units like Aeroex’s Air Fit come equipped with HEPA units.

Mist Collectors

Mist Extraction for CNC Machining

Employing the use of a mist extraction system in tandem with regular CNC machining equipment operations can aid in preventing risks that you may not easily identify with the naked eye. Luckily, Aeroex Technologies engineered mist collection systems are built with the unique needs of CNC equipment processes in mind. Our mist collectors effectively remove mist from the workplace environment to ensure your machine operators and facility equipment are not exposed to health and operational risks down the line. 

In this blog we uncover the mist extraction needs unique to CNC machining and how Aeroex Technologies’ offers a reliable and efficient mist collection system tailor-made to meet these needs. 

The Important Role of CNC Machining Processes for Manufacturing 

CNC machining equipment plays a fundamental role in manufacturing for their ability to produce accurate and specific parts by turning raw materials into final products. CNC stands for Computer Numerical Control, which represents two standard methods (3D printing technology and FDM) to build prototypes all from a computer software file. CNC machining has been used to manufacture a range of materials including wood, metals, and plastics.

Unfortunately, a common byproduct of CNC machining is chip formation. Chip formation occurs when the machine tool makes contact with the edge of the material that is being worked on. Common with CNC machining processes such as milling, grinding, honing, and turning – chip formation is imminent. Chip formation can detriment the production process leading to shortened tool life, stoppages, lack-luster surface finishes, and can increase the likelihood of safety hazards from occurring. 

Many CNC machine operations will employ the use of a high-pressure coolant to deal with chip formation control. High-pressure coolants offer a myriad of benefits when it comes to controlling chip formation, but an unfortunate byproduct is that it leads to the dispersion of coolant mist into the air which can lead to slick work environments, and post significant health risks to facility personnel as well as to other equipment in your facility. 

It is for this reason that effectively controlling the dispersion of coolant mist is regulated by OSHA, NIOSH, ACHGI, and Health Canada. All of these governing bodies dictate legislation to limit exposure to harmful workplace pollutants like oil and coolant mist. 

Health Risks Associated with Coolant Mist Exposure 

Exposure to coolant mist and toxic fumes include irritation of the eyes, skin, mouth, and throat, and can lead to other symptoms like headache, shortness of breath, fever, rapid heart rate and vomiting. Persistent and unchecked long-term exposure to oil and coolant mist can increase the likelihood of developing more serious respiratory and skin diseases including cancer.

Despite the growing trend toward the regular use of high-pressure coolant for CNC machining applications, there has been a gap for a solution that effectively filters through the airborne particulate that high-pressure coolants disperse into the working environment. 

Aeroex Technologies’ Mist Extraction for CNC Machining Solution

Because CNC machining utilizes 3D printing technology, the team of experts at Aeroex Technologies have conducted extensive research to inform engineering efforts when it comes to addressing the types of mist and fumes emitted by 3D printing. Paying special attention to factors like composition and quantity, the Aeroex team understood the importance that source capture extraction systems play in the more modular processes in which 3D printing emits mist and fumes. 

Source capture filtration effectively and efficiently mitigates dispersion of harmful mists and fumes from being emitted into the working environment, as it is captured at the source. Ambient filtration in contrast, collects unwanted airborne particulates that have not been filtered immediately via source capture filtration. Depending on your facility needs, employing the use of both ambient and source capture filtration might be the best solution for you. We recommend reaching out to learn more about how Aeroex Technologies can propose a mist collection system that meets your unique facility needs.

Mist Collectors

Mist Collector Based on Calculated Airflow

Oil and coolant mist collectors are often defined by the smallest particle size they can filter, but calculated airflow is just as important. In fact, focusing on filtration size or failing to consider other factors like airflow may be leading to less than optimal performance. Filtration size might be the right starting point, but we’ll go over some of the reasons why you need to consider airflow when using oil and coolant mist collectors for industrial air filtration. 

What Is Air Flow and Why Is It Important for Industrial Air Filtration

In the context of industrial air filtration, airflow describes the nature and rate at which air is circulated and discharged using a mechanical ventilation system. This could be across a facility, within a particular production room, or in a machine enclosure. Airflow is measured using units of volume (e.g. cubic feet or meters) and time (e.g. minutes or seconds). Aeroex uses cubic feet per minute (or “cfm”) as its standard unit of measurement. Airflow also has a direction or vector, such as from areas of high to low pressure or from a source of forced air to a source of air capture. The direction, volume, and velocity of airflow all play important factors in the performance and outcomes of your filtration scheme. 

Airflow is important for industrial air filtration because it is a key determinant of the ability to capture or mitigate the effects of airborne contamination caused by industrial processes like machining. This can be true both at the macro level for a large facility or at the source of a single machine. Consider the following examples.

Example #1 – Air Flow Considerations for Source Control Applications 

You are machining at high cycles and use coolants or lubricants to maintain the temperature of your tools, but need to maintain visibility or prevent the over-accumulation of oils and mists. Therefore, your ventilation and oil mist collection system will need to recycle the enclosure every few seconds. By extension, your oil mist collector needs to have the airflow capacity to do so. The “direction” of airflow is of less concern here because it is a closed system with source control. Aeroex often recommends source control solutions because contaminants are captured quickly before they are released into the shop atmosphere where they disperse – you can often capture at the source with less airflow than what is required under ambient conditions. 

Example #2 – Air Flow Considerations for Ambient Control Solutions 

You may use an ambient control method for air filtration when source control is not feasible – for example, some grinding applications without enclosures may not achieve 100% success with source control. Ambient control is also used as a “finishing” method complementing source control to achieve the cleanest possible air. Here, you need to consider the entire volume of the room rather than just an enclosure, and you also need to consider the direction of airflow relative to your air filtration system. The placement of different sinks and sources of ventilation will determine the overall flow in a facility, and proper engineering is needed to ensure the entire room is circulated. If there are corners circulated less frequently or at limited capacity then there are areas of higher risk. Ambient control often requires high airflow because you will be recycling an entire room of air, usually several times per hour.

Engineering the airflow of a room or facility is a complex topic, and deploying an industrial air filtration system may mean consulting an engineer – Aeroex has experienced staff who can make sure any deployment is planned properly. The below figure depicts some examples of common airflow dynamics.

Risks of Inadequate or Mismatched Air Flow

Performance is often described in terms of the smallest size of particles captured by a filter, but if your oil mist collector cannot deliver the required airflow then the contaminants are not being removed at a rate that can ensure the quality or safety you expect. The filters selected can impinge on airflow, especially among cheaper membrane filters without the proper screening or depth loading to prevent clogging or deliver higher volumes of air. While filters may often guarantee using things like the HEPA standard, an improperly sized filter will negatively impact the air flow generated. Once airflow is restricted, contaminants will bypass the filter and carry into the airspace downstream of your filtration system – an outcome your filtration system was intended to prevent. For this reason, Aeroex uses depth-loading filters and provides a wide range of capacity options, ranging anywhere from hundreds of cubic feet per minute to thousands. 

While it’s common among other suppliers to be overpromised on a system with inadequate airflow, you also want to avoid overpaying for capacity you don’t need at additional cost. 

Why Is Filtration Size Mistakenly Emphasized Over Airflow?

Within the industrial air filtration space, we often speak in terms of particle size because it’s something all applications can relate to. Contaminant particle size, within a theoretical range, is common to all applications. While particle size can vary with temperature, dispersion method, etc, its chemical composition means that particle size will be within an accepted range. This means that the design and business case of a filtration system can relate to everyone via consideration of particle size. This commonality creates a shared language but can omit the factors that make each situation unique (notably your airflow requirements).

Airflow will depend on your enclosure size, amount of oils and coolants being applied, machine type and technique used, desired air exchange frequency, etc. At the ambient level, you will also need to consider the size and orientation of the facility, along with the other airflow contributors.

So, while filtration size can start the conversation, don’t make the mistake of not selecting your mist collector based on calculated airflow. At Aeroex, we will diligently and patiently understand all your needs including calculated airflow to recommend the right mist collector.

Important Facts About Air Filters and Filtration

Aeroex is continuing our campaign to arm you with facts about air purification! You can use the same information we use to design our purification systems to understand the types of filters companies offer and the underlying filtration technology used.

Filter Type and Filter Depth

In our last blog, we discussed what air purification is and the importance of not just looking at filter efficiency but also the capacity of filtering a sufficient volume of air to achieve your target number of air exchanges. Another important factor in air purification performance is the filter depth and material.

Previously, we explained the HEPA industry standard. HEPA certifies a filter as being capable of capturing 99.97% of 0.3 micron particles, usually achieved through a series of randomly aligned fibers. Unfortunately, the HEPA standard only certifies the ability of a filter to perform this filtration under ideal conditions and does not certify the long-term performance of the filter. This leads to filters that technically meet the HEPA standard but not your expectations for performance. The common distinction for systems are whether they use depth filters or membrane filters.

Comparing Depth Filters and Membrane Filters

While depth filters and membrane filters can both be HEPA certified, they do not operate the same. Membrane filters are thin but intricate, stopping nearly all particles above the uniform filter size. Unfortunately, they also clog easily because only a small amount of filter media is available. Conversely, a depth-loading filter has a much “thicker” interface for contaminant particles, creating more filtration opportunities. The nature of depth loading means this does not clog the filter and impede performance.

Don’t Get Stuck With Cheap Pleated Filters!

Membrane filters in other industries have many essential uses but in air purification, membrane filters tend to be cheap pleated HEPA filters that clog easily. So, it is common to see claims about the performance of the HEPA standard that ignore how often these filters need to be replaced. It is for this reason that Aeroex instead uses a depth-loading filter along with multi-stage filtration – so that when you pay for a HEPA filter, you are using its true purpose of only removing the smallest particles. 

When you see a discussion of HEPA filters, remember the information shared by Aeroex and other trusted sources! If you ever have questions about the science of air purification, do not hesitate to contact Aeroex.

Common Misconceptions about Air Quality

Indoor air quality is widely recognized as a key strategy for mitigating airborne viruses, but in the rush to learn about air purification there have been instances of disinformation or misleading claims about what works and what doesn’t. Aeroex has been in the business for over 20 years but we are seeing newcomers jump on the COVID opportunity, misleading their customers. We want to arm you with the facts so you can restore confidence in the promises of air purification. 

What is Air Purification?

Air purification is the process of filtering and removing suspended particles. So, air purification relies on ways of removing these particles, most commonly through filtration. While this seems simple, the range of pollutant types and particle sizes means air purification quickly gets challenging without the right tools.

So If Some Bad Particles Are Small, All You Need Is A Small Enough Filter Right?

Wrong! Understanding particle science is the first step but it misses something. Having a very fine filter is good, but if it can’t filter particles faster than they are spreading you’re not sufficiently purifying the space. This is why air exchanges are important, the frequency that a volume of filtered air is replaced – it must be higher than the source in order to maintain air purification (depicted below). Often, many times that frequency. Not to mention factors like the volume of the facility/room. Before doing a detailed analysis of airflow, it’s good to start with a simple calculation of air volume in a room.

Know Your Filters

Companies may try to confuse you with proprietary naming, but knowing the international standards for filtration will help you navigate their claims. The two main types you should know are MERV and HEPA. MERV is a standard certified by the EPA for 95% particles from 10 to 0.3 microns – for some applications, this is effective enough. HEPA goes further, capturing 99.97% of 0.3 micron particles. Start by learning the particle size of your contaminants and reference this against the filter rating. Consider this in the context of other filter characteristics like filtration type (pleated membrane vs depth filter, another Aeroex passion!) and air handling capacity (commonly measured in cubic feet per minute).

Don’t Be Fooled

Air exchanges are a critical factor many vendors conveniently ignore – you can have the best filter for small contaminant particles in the world and if it doesn’t have air exchange capacity your room could be full of impurities. And, this is before even considering how to handle a ranging mixture of particle sizes! At best this leads to the wrong purchase, but at worst many people are making decisions with false promises that risk health and safety. Make sure to consider both filter size and exchange rate, plus the many other tips Aeroex has. Stay tuned for more!
