An air shower (or air shower passage) is a device used in a specific environment, such as aseptic rooms, clean rooms, laboratories, etc., to provide people or items with efficient and continuous air flushing to remove dust, microorganisms and other pollutants from the surface, thus maintaining the cleanliness of the environment.
The main features of the air shower include:
Efficient air washing: the air shower room through high speed, evenly from the top or side spray clean air, forming a similar "curtain" air flow, the surface of the particles, microorganisms and other pollutants away, so as to maintain the cleanliness of the air and surface.
Full coverage: Air shower rooms are usually designed for full coverage to ensure that people or items passing through the shower can receive air flushing from multiple directions to maximize the removal of surface contaminants.
Control system: The air shower room is usually equipped with advanced control system, including the control of wind speed, temperature, humidity and other parameters, to ensure the stable and reliable operation of the air shower room.
