Panel Filters

Types of panel filters:

• Glass
• Synthetic
• Pleated
• MiniCell
• Fan Coil Filters
• Metal
• Polyfoam.

Each of these types of panel filters has its perks and is suitable for specific applications.

Glass panel filters provide a low level of filtration. They are used as a primary filtration method, often protecting different types of complicated devices from dust particles. They are also widely used in spray booths, because of their relatively low price.

Synthetic panel filters are a grade above. They provide a better filtration compared to glass panel filters. They are often used in ductwork as an inline filter.

Pleated panel filters are probably the most common industrial air filters. They are used in situations where minimal pressure drop is required. Thanks to the larger surface of those type of panel filters, they are ideal for such cases. You can often see these panel filters inside inline filter boxes.

Fan coil filters are commonly applied when additional protection of the system’s fan is needed. They are cheap and easy to install. They are also widely used just before inline heating elements, in order to stop any large particles that got their way inside the ductwork.

Metal panel filters are mostly used in industrial systems as initial filtration points. They are made out of galvanized steel or stainless steel. Known for their high endurance, those filters are commonly used in commercial-grade workshops.

Polyfoam panel filters are used in similar cases as the metal panel filters. The difference between the two is that the polyfoam filters provide better filtration. Just like the metal panel filters, polyfoam filters could be washed multiple times. This makes them ideal for woodworking shops, where fine dust can easily be washed away.

Panel Filters in HVAC

Besides their extensive use in paint booths, panel filters are also used as air handling unit filters. They are good for providing the first line of filtration that stops solid particles from entering the air stream and damaging internal components. Thanks to their compact design and water-resistant frames, they are often preferred as HVAC filters. The difference in temperature could lead to condensation, which is no problem for most panel filters. The various sizes available on the market can fit any ductwork and duct accessories (inline filter boxes, various sizes of grilles & louvres), even the “retrofitted” ones.

Sizes available on the market range from 245x245 all the way up to 692x495 millimetres. The thickness of panel HVAC filters ranges from 20mm. to 95mm. with standard thicknesses of 20mm., 45mm., 95mm. but you can always stack them if needed.

Depending on the work environment, you will often need to protect expensive equipment from debris or damage from fine dust. This is where a panel filter with a G2 rate of filtration will do wonders. For when you really need to clean the air in a room, you will need a G4 rated filter. The air filtration quality of the panel HVAC filters is commonly G2 or G4. Specifically for HVAC filters, the most used panel filters are pleated filters with a G4 rating. They are also used as spare HVAC filters for inline filter boxes. That’s because of their low-pressure drop.
