The biggest contaminat making dust and viruses generated in the highly clean air environments including clean room and bio-clean rooms are men entering them.
Following that, air showers are self-contained chambers installed at the entrance of cleanroom and other controlled environments in orders to minimize particular matters enter-ing or existing in the clean space. Humands and materials entering or existing in the controlled environment are "scrubbed" by high velocities.
Adopting pre-filter and HEPA filtration system, the cleanliness of the air shower reaches 99,99% due to adjustable stainless steel nozzle, big air volume and low noise fan. Air speed can reach the level of 25m/s from air outlet and 18m/s for human body.
