Air shower (room)
From Wikipedia, the free encyclopedia
The term 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.
