Fan Filter Unit (Pre-Owned)

A fan filter unit (FFU) is a type of motorized air filtering equipment, which is used to supply purified air to cleanrooms, laboratories, medical facilities or microenvironments by removing harmful airborne particles from recirculating air. The units are installed within the system's ceiling or floor grid. FFUs can be used in place of a more conventional recirculating air unit such as a ducted or plenum design. FFUs are often used because of height restrictions in the space. They are the only systems that work in setups with smaller internal floor dimensions.
