Static Pass Box
Pass Box
Standard Pass Box is an essential support device for cleanrooms, engineered to facilitate the safe and contamination free transfer of small materials between clean and non-clean zones.
It effectively reduces the need to open main cleanroom doors, maintaining the overall pressure balance and reducing the risk of airborne contaminants.
Constructed using high quality cold rolled steel with electrostatic spray coating, the pass box ensures long term durability, cleanliness, and easy maintenance. The inner lining is made of stainless steel to support hygienic standards and prevent particle accumulation making it ideal for pharmaceutical, biotech, and electronics manufacturing environments.
Available in three models FST-600, FST-800, and FST-1000 these units feature wall opening adjustments for flexible installation, and mechanically interlocked doors that prevent both sides from opening at once, ensuring a secure transfer environment.
Dimensions range from W760×D670×H700 mm up to W1160×D1070×H1100 mm to suit varying operational needs.
