A fan filter unit (FFU) is a of type of air filtering equipment. It is used to supply purified 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.
Air shower can refer to the specialized antechamber which is passed through before entering a cleanroom in order to blow off excess dust particles from cleanroom personnel before they enter, to minimize contamination. HEPA filters are generally used to decontaminate a room by filtering out particles greater than 0.3 micrometres in size.
This kind of local purifying equipment is located between clean room and unclean room. They are designed to blow air in different directions. Single-side shower, double-side shower, three-side shower and top shower. Spraying wind speed usually goes above 25 m/s through stainless steel nozzles.

The function of the car air filter:
For a sound operation of the engine, there must be a lot of pure air is inhaled. If harmful substances (dust, colloid, alumina, acidification iron, etc) in the air are inhaled into the engine, cylinder and piston assembly will increase the burden, making cylinder and piston components abnormal wear that would mixed with engine oil, and more substantial wear is possible, which may result in the deterioration of the engine performance, shorten the engine life, and prevent engine wear. At the same time, air filter obtains silencer function.
