1、Air Shower 

Air shower series are versatile local purification devices installed between cleanrooms and non-clean areas. When personnel or goods enter clean zones, the shower emits purified air to remove dust particles, effectively blocking contamination sources. Equipped with electronically interlocked doors, it acts as an airlock to prevent unfiltered air entry.
