Fan Filter Units

​BASX Fan Filter Units are typically used in place of a conventional recirculating air unit due to space height restrictions and are often installed in a ceiling grid system or suspended from a support structure. Recirculated air is purified through a prefilter installed on the top and blown through a HEPA or ULPA filter into a cleanroom.
