Fan Filter Unit ATV - FFU - 4*3

A FAN FILTER UNIT (FFU) is a type of air filtering equipment. It is used to supply purifiled air to cleanrooms or microenvironments by filtering out harmful airborne particles from recirculating air. The units are installed within the system’s ceiling or floor grid. Large cleanrooms 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.
