What is a HEPA Filter?

commercial hepa filters

High-efficiency particulate arrestance (HEPA) is a type of air filter. When a Filter meets HEPA grade requirements they have several possible applications including clean rooms, medical facilities, aircraft and homes. The filter must appease certain standards of productivity set by the United States Department of Energy. To qualify as HEPA by US government standards, an air filter must remove (from the air that passes through) 99.97% of particles that have a size of 0.3 µm.

Who uses V-Bank filters?

v bank air filter

A V-Bank filter is what we call a mini-pleated filter; it’s a high-efficiency filter with a higher media area than a standard box filter. The standard size is still 24 x 24 x 12, like the box filter, but there’s a big difference between the mini-pleated V-Bank filter and a box filter: most box filters have a metal frame and don’t have a large amount of filtration media. The actual pleat packs, which is what the media is manufactured into, are installed into the V-Bank filter in a ‘V’ shape – hence the term V-Bank. The majority of ours are 4 V’s.

What are evaporating cooling pads?

evaporative cooler pads

EFS primarily uses what would be considered evaporative cooling pads. Evaporative cooling pads are used to cool the air and keep moisture out of it. Their applications are primarily in gas turbine power plants, but there have been requests for them to be used in pig and mushroom farms, presumably for the same purpose.
