Transfer Window
The transfer window is an auxiliary equipment for clean rooms. It is mainly used to transfer small items between clean areas and between clean areas and non-clean areas to reduce the number of times the clean room opens and reduce the pollution to the clean room.
Principle of transfer window
The transfer window is a device installed at the entrance and exit of a clean room or between rooms with different cleanliness levels to block indoor and outdoor airflow when transferring goods to prevent contaminated air from entering cleaner areas and causing cross-contamination. When the air shower type transfer window is transferring materials, the top blows out high-speed, clean airflow to blow away dust particles on the surface of the goods.
At this time, the doors on both sides can be opened or closed, and the clean air flow acts as an airlock to ensure that the air outside the clean room does not affect the cleanliness of the room.Sealing strips are installed on the inner sides of the doors on both sides of the transfer window to ensure the air tightness of the transfer window.
