Air Shower: Excellence in Details, Control at the Entrance

Air showers are essential transition units installed between non-clean and clean zones. Prior to entry, all personnel/materials must pass through the air shower, where high-velocity HEPA-filtered air jets remove surface particulates, effectively preventing contaminants from being carried in. Featuring electronically interlocked front and rear doors, these units function as airlocks to reliably isolate unfiltered air and maintain cleanroom environmental quality.
