Fan Filter Units (FFU) are essential for the supply of ‘purified air’ and are most commonly used in cleanrooms, laboratories, medical facilities and micro-environments. They are motorised units which contain their own integrated HEPA-filters, fans and control systems, which enable them to remove harmful airborne particles from the air supply that is constantly being recirculated.
The units are installed within a facility’s ceiling or floor grid. Larger cleanrooms tend to require a proportionally large number of FFUs, which in some cases may range from several hundred to several thousand units.
