The Pass Box is a device that is arranged between the clean room entrance and exit or different cleanliness level rooms to block the indoor and outdoor airflow when the goods are delivered, so as to prevent polluted air from entering the clean area and causing cross-contamination. When the air showering pass box conveys the material, the top part blows out the high-speed, clean airflow, and blows off the dust particles on the surface of the cargo. At this time, the doors on both sides can be opened or closed, and the clean airflow acts as an air brake to ensure the outdoor of the clean room. Air does not affect the cleanliness of the room. A special sealing strip is installed on the inner side of the door on both sides of the pass box to ensure the airtightness of the pass box.
