What is a Pass Box?
A pass box is a specialized device used in clean room environments, primarily designed for the transfer of small items between one clean area and another clean area, or between a non-clean area and a clean area.
Its main function is to prevent contamination by minimizing the direct exposure of the clean room to external environments, thereby preserving the controlled conditions like air purity, pressure, and particle levels throughout the transfer process.
Types of Pass Boxes

Static Pass Box
A Static Pass Box is a contamination control device designed for material transfer between areas of equal cleanliness levels, utilizing dual doors as physical barriers along with optional UV disinfection, while lacking active airflow systems such as HEPA filters or fans.
- Electronic Interlocking Static Pass Box : Uses electromagnetic locks and sensors to ensure only one door opens at a time, often with automated UV sterilization for contamination control.
- Mechanical Interlocking Static Pass Box : Relies on physical linkages to mechanically block simultaneous door opening, requiring no power.
Dynamic Pass Box
Dynamic Pass Box is an active transfer device that maintains contamination control between different cleanliness zones using forced HEPA-filtered airflow and pressure regulation.
