Electrical Enclosure Air Filters: The Ultimate FAQ Guide

How Does Enclosure Air Filtration Work?

Enclosure air filtration system is made of different layers or structures that remove dust, debris, insects, and moisture in the air flowing into the electrical cabinet.

Depending on the type of air filtration media such as polyester or polypropylene with microfibers, they can remove very tiny and invisible particles (up to 10 microns or less) from the air.

Moreover, some enclosure air filtration systems feature louver systems that prevent water ingress.

Even with all these filtration systems, enclosure air filtration should still guarantee a laminar flow of air into the electrical cabinet.

Can Electrical Enclosure Air Filters Withstand Harsh Environment Conditions?

Sim.

However, they must have special features that protect enclosure air filter systems and electronics in the cabinet.

Some of the key features include:

i. High heat or flame-retardant material (should be a UL rated)

ii. Louver to help in draining water droplets

iii. Waterproof hood

iv. Cascaded ventilation system

v. High grade and fine filtration media

vi. 100% compliant with the international standards and regulations

vii. Easy to clean/replace without compromising air filtration process

viii. Can offer EMI shielding

ix. Corrosion-resistant frame/parts

What is Electrical Enclosure Air Filter?

It is a device or a set of systems that allow only clean (air free from dirt, dust, moisture or any other contaminants) to flow into the electrical enclosure.

Even with filtration media that trap contaminants, it allows for a free flow of air with minimal restrictions.

Can Enclosure Air Filters Replace Enclosure Louvers?

Sim.

However, you should do a cost-benefit analysis before replacing enclosure louvers with enclosure filter.

 Louver vs. filter

In fact, if you can combine filter and louver systems, you will have a more comprehensive enclosure ventilation system.

Moreover, you can also have a fan system, filter, and louver as one single unit.

Are there Electrical Enclosures with HEPA Filters?

High Efficiency Particulate Air or High-Efficiency Particulate Absorbing (HEPA) are special types of filters that remove at least 99.95% according to EU standards or 99.97% as per the U.S. standards of particles passing through them.

The particle size here should be equal to or greater than 0.3 µm.

You can find such HEPA filters in biosafety electrical enclosures.

Or, they are common in electrical enclosures that require biosafety level 1, 2, or 3.

When Should You Replace Enclosure Air Filters?

You should replace electrical enclosure air filters when:

• You cannot clean the electrical air enclosure anymore
• There is increased air resistance in the enclosure (air does not flow seamlessly in/out of the enclosure)
• Electrical enclosure begins to overheat frequently due to poor airflow
• The enclosure air filter is permanently clogged

Remember, through regular inspection; you will know when to replace enclosure air filters.

When they need replacement or cleaning, you will see dirt, particle, or debris covering the entire surface of the enclosure filter.

Furthermore, the frequency of maintenance or replacing enclosure air filters will depend on the working conditions and environment.

Are Enclosure Fan and Filters NEMA Rated?

NEMA ratings stipulate specific environments where you can use an electrical enclosure. It is not concerned about electrical enclosure fans.

However, since fans may form part of the enclosure system, their inclusion must not compromise the NEMA enclosure type rating.

It does not matter whether the electrical enclosure air filter is at the intake or exhaust section.

What is the Best Material for Electrical Enclosure Filters?

Depending on the environment or application, electrical enclosure filters are made from different materials for optimal performance.

Enclosure filter material

Some of the most common electrical enclosure filter media materials include:

• Polyurethane filter foam
• Polypropylene and modacrylic fibers
• Non-woven polyester
• Wire cloth
• Synthetic fiber such as G2, G3, or G4. They are mainly made of polymer.

The filter frame is fabricated from plastic or metal such as aluminum, galvanized steel, stainless steel, etc.

At times, the electrical enclosure air filter manufacturers may use dissimilar materials for the filter media.

The aim is to produce a steady static electric charge that improves air filtration.

Such enclosure filter media remove very tiny particles.

How do you Install Electrical Enclosure Air Filter?

Since most electrical enclosure air filters come as fully assembled kits, the installation process is quite simple.

i. Identify where you want to install the enclosure filter

ii. If you’re replacing an old enclosure filter – carefully remove it then wipe the area around the enclosure which was in contact with the filter

iii. Properly position the enclosure filter

iv. Using an appropriate fastening mechanism, secure the filter in place

Observação: This procedure will vary from one electrical enclosure to another.

It will depend on where the manufacturer installed the enclosure filter.

Always review the technical drawing of the electrical enclosure if you want to get it right.

Can You Add Air Filters on an Enclosure that Did Not Have One?

It’s possible; however, you should be extra careful here since you may damage the enclosure.

You need to consult the electrical enclosure manufacturer or hire an expert.

Remember, every electrical enclosure is designed for specific applications based on the IP and NEMA rating.

Therefore, adding or removing certain accessories may compromise their functionality.

What is the Difference between Exhaust Grilles and Enclosure Filters?

Exhaust grilles are fixed openings (may have metal strips or mesh wire) installed in the electrical enclosures.

They allow a constant volume of air to leave the enclosure but does not filter.

Enclosure filters are openings with special media (material) that allow a constant volume of air to flow in and out of the electrical enclosure.

More importantly, its filter media removes debris on contaminants in the air (allows clean air to pass through).

Are Electrical Enclosure Air Filters Same as Enclosure Ventilation Systems?

Electrical enclosure air filters are part of enclosure ventilation systems.

Since through the filters, air can flow in and out of the enclosure.

Even though the enclosure ventilation system involves the flow of air in an out of the enclosure, it includes a range of accessories such as louver, HVAC, fans, air filters, etc.

What is Electrical Enclosure Filter Fan?

It is an accessory that combines both enclosure fan systems and enclosure filters.

 Enclosure filter fan

It implies an enclosure filter fan forces air into/out of the electrical enclosure.

At the same time, the filter will remove contaminants (debris, dirt, dust, insects, etc.) from the air before it circulates in the electrical enclosure.

As a result, it provides an efficient, reliable, and cost-effective way of cooling electrical enclosure system.

Mostly, enclosure filter fans help maintain the temperature below the surrounding environment.

Is Air Purifier Fan Same as Electrical Enclosure Air Filters?

No.

However, both air purifier e air filters do the same task – removing contaminants from the air.

The difference comes in the degree of “cleanliness.”

That is, air purifier “sanitize air” by removing pathogen, mold or fungus, alongside other contaminants such as debris, dust particles, etc.

Still, it’s not economical to install air purifiers in electrical enclosures.

Electrical enclosure air filters can provide the needed air quality.

How Can You Mount Electrical Enclosure Air Filters?

Depending on the design of the enclosure, you can mount electrical enclosure air filters on any section of the electrical cabinet.

However, the mounting position must provide an optimal flow of air to and from the enclosure without obstructions.

You can mount the electrical enclosure air filters using bolts and nuts, screws, clips or adhesives.

The enclosure air filter manufacturer will recommend the best mounting mechanism.

What are the Advantages of Electrical Enclosure Air Filters?

• Keeps electrical enclosures free from contaminants such as dirt, debris, insects, moisture, etc.
• Provides efficient enclosure cooling mechanism by allowing free flow of air
• Offers a cost-effective and reliable cooling mechanism
• Eliminates frequent enclosure maintenance such as cleaning hence, reducing the cost of operation
• Increases enclosure components service lifespan since it prevents overheating

Are Enclosure Air Filters Part of Enclosure Cooling System?

Yes, air filters form an integral part of the enclosure cooling system.

Enclosure air filters ensure an uninterrupted free flow of uncontaminated air (free from dirt, debris or moisture) into the electrical cabinet.

How Does Air Flow Affect Electrical Enclosure Efficiency?

Electrical enclosure and its components have recommended operating temperature.

For instance, quite a number of variable frequency drives (VFD), I/O cards, controller, or sensors will only work within a specific temperature range.

Besides, moisture and other contaminants may greatly affect the efficiency of components.

For some components, corrosion and dirt accumulation will create an additional layer that will compromise the integrity of signal transmission.

Also, an enclosure that does not allow for optimal heat dissipation and temperature control will result in inefficiency and subsequent component failure.

These imply, to maintain the recommended operating temperature for optimal efficiency, the enclosure should allow sufficient flow of cooling air to the components.

In short, inefficient airflow for cooling may cause overheating that will result in component failure.

To improve efficiency, you should consider the following:

i. Consider maximum airflow for efficient cooling of heat dissipated by components

ii. Strategically position airflow mechanisms to eliminate hot spots

iii. For areas with high ambient temperature consider closed-closed loop cooling options such as air conditioners

iv. Install high heat dissipating components separately from those that produce low heat

v. Mount devices correctly (horizontally or vertically) for an optimal airflow when cooling

What is the Best Air Filters for IP Rated Enclosures?

IP rated enclosures come in different options, for varying degrees of contaminant protection.

Therefore, the type of enclosure air filter will vary depending on the IP rating.

From their design to the choice of the air filter medium, they must conform to the set IEC Standard 60529.

Implying, you must understand the specific requirement of IP rated enclosure to choose highly efficient filter media with the right degree of protection.

Besides, the enclosure may have additional protection features such as:

• High-quality filter frame
• Robust enclosure filter mounting mechanism
• Louver system
• Gasket

What is the Maximum Dirt Load for Enclosure Air Filters?

Electrical enclosure air filter dirt load depends on:

• Filter media material
• Size of enclosure filter
• Enclosure filter media design technology
