Item # HAC-4, High Velocity HEPA Air Curtain

Clean Room Depot’s high velocity air curtain is a portable and effective doorway mounted clean room entry/exit system. It is designed to reduce the introduction of contaminants into a clean area, by producing a barrier or curtain of ultra clean HEPA air. This allows rapid clean room entry/exit of personnel and can be utilized as an inexpensive alternative to an air shower where absolute clean room garment cleanliness is not mandatory.
