Principle of cleanroom pass box

The pass through box is a device set at the entrance and exit of a clean room to block indoor and outdoor airflow when transferring materials to prevent polluted air from entering a more pristine area and causing cross-contamination.

The air shower blows a high-speed, clean airflow from the top when materials through the box blow off the dust particles on the surface. At this time, the doors on both sides should be open or close, and the clean airflow acts as an airlock to ensure that the air will not affect the cleanliness of the clean room.
