Fan Filter Unit (FFU) is a of type of motorized air filtering equipment. It is used to supply purified air to clean-rooms, laboratories, medical facilities or micro environments by removing harmful airborne particles from recirculating air. The units are installed within the system's ceiling or floor grid. Large clean-rooms require a proportionally large number of FFUs, which in some cases may range from several hundred to several thousand. Units often contain their own pre-filter, HEPA filter and internally controllable fan air distribution.
