Cleanroom Static Pass Box

Its main function is to reduce cross-contamination by limiting direct airflow and human movement between clean areas. It provides a safe, enclosed way to transfer tools, samples, or materials.

Static Pass Boxes are commonly used in pharmaceutical manufacturing, biotechnology, hospitals, laboratories, electronics, and semiconductor industries.

A Static Pass Box has no built-in ventilation system and relies on the cleanroom environment. In contrast, a Dynamic Pass Box has a HEPA-filtered air circulation system for active air purification.

Mechanical interlock features a built-in linkage mechanism that physically locks the opposite door when one is open, allowing the second door to open only after the first is fully closed and latched. Alternatively, electronic interlock systems use sensors and electromagnetic locks to detect door status and automatically lock the other door during operation. This model adopts a mechanical interlock system for reliable, power-free operation. Electronic interlock options are also available upon request.

Use the UV lamp before or after transferring items to sterilize surfaces and reduce contamination risk, especially in cleanrooms where sterile conditions are required. Always turn off the lamp before opening the door.
