Air Shower, also known as air shower, clean air shower, and purification air shower. The air shower is an essential passageway for entering a cleanroom, reducing contamination issues brought by entry and exit. It is a versatile local purification equipment installed between cleanrooms and non-cleanrooms. When people and goods need to enter the clean area, they must pass through the air shower, which blows out clean air to remove dust carried by people and goods, effectively blocking or reducing dust sources entering the clean area. The two doors of the air shower/goods shower are electronically interlocked, also serving as a gas lock, preventing unclean air from entering the clean area.
