Pass box is an auxiliary air purification device designed specifically for cleanrooms, primarily used for the safe transfer of small items between clean areas, or between clean and non-clean areas. Widely used in pharmaceutical plants, biological laboratories, hospitals, and sectors such as microelectronics, food processing, precision instrumentation, and optoelectronics.
Pass Box Feature:
No protrusion indoors and outdoors with high space utilization rate. The entire pass box is embedded inside the partition wall to achieve a completely flush wall surface without protruding outward from the door frame.
Superior air tightness compared with outward-opening doors. The embedded design fully conceals the door frame within the cabinet body; combined with sealing strips, it delivers tighter adhesion.
Flush wall surface free of dust accumulation dead corners. With no outward-protruding door frame, there are no dust-trapping ledges or gaps, effectively preventing dust buildup, water pooling and bacterial retention.
Integrated, flush-mount design that ensures a perfectly level surface on both the interior and exterior sides (True Flush), with no protrusions extending from the frame or door leaf.
Maximizes space utilization and eliminates risks such as material carts colliding with the equipment or tearing operators' sterile suits.
Concealed door frame structure paired with a medical-grade, high-resilience, one-piece molded gasket, ensuring multi-dimensional, uniform compression when the door is closed.
Delivers superior overall airtightness, creating an impenetrable airflow barrier under high-pressure differential conditions and effectively preventing even minor pressure leaks.
Engineered to meet rigorous GMP sterile validation standards, featuring no protruding frames, external hinges, or exposed screw holes.
The completely flat, mirror-finish surface facilitates easy manual cleaning and ensures 100% coverage during disinfection, leaving no dead zones.
