Cleanroom air shower is a highly versatile partial purification device installed in the passage of clean room and non-clean room, used to reduce the pollution problems caused by entering and leaving the clean room. When people or goods need to enter the clean area, they must be sprayed and showered in this equipment. The clean air blown out can remove the dust carried by people or goods, and can effectively prevent or reduce dust from entering the clean area. The front and rear doors of the air shower are electronically interlocked and act as air locks to prevent un-purified air from entering the clean area.
