Air Shower units are specially designed enclosed entry systems installed between non-clean and cleanroom areas to minimize particulate contamination before personnel or material enter controlled environments. The system delivers high-velocity HEPA-filtered air through strategically positioned nozzles to effectively remove dust, lint, and loose contaminants from garments and exposed surfaces.
Designed for pharmaceutical, biotechnology, electronics, healthcare, and cleanroom applications, the Air Shower helps maintain cleanliness standards and supports contamination control protocols in critical production areas.
Working Principle
The Air Shower operates by recirculating high-velocity HEPA-filtered air through adjustable stainless steel nozzles positioned along the side walls. During the air shower cycle, contaminants are dislodged from personnel or material surfaces and captured through the filtration system before clean air is recirculated.
An electro-mechanical interlocking system prevents both doors from opening simultaneously, ensuring proper contamination control and maintaining cleanroom integrity.
