With over 10+ years of industry expertise, we specialize in manufacturing GMP-compliant static pass boxes that ensure zero cross-contamination during material transfer between controlled environments.
What is a Static Pass Box? Understanding Pass-Through Chambers
A static pass box (also called a pass-through chamber or material transfer box) is a critical cleanroom equipment designed to transfer materials between two controlled environments without compromising air quality or introducing contamination.
How Static Pass Boxes Work:
Interlocking Door Mechanism: When one door opens, the other automatically remains locked, preventing simultaneous access
Particle Reduction: Surface contaminants are minimized during the transfer process
Zero Air Movement: Unlike dynamic pass boxes, static models operate without airflow or filtration systems
Grade C Compliance: Ideal for pharmaceutical cleanrooms requiring Grade C classification
Key Principle: Static pass boxes are designed for transferring materials between two rooms of equal cleanliness levels only – never between clean and non-clean areas.
