Transfer window is an auxiliary equipment in clean rooms, mainly used for the transfer of small items between clean areas and between clean areas and non clean areas, in order to reduce the number of times the clean room is opened and minimize pollution to the clean room. The transfer window is made of stainless steel plate, which is flat and smooth. The two doors are interlocked to effectively prevent cross contamination, equipped with electronic or mechanical interlocking devices and equipped with ultraviolet sterilization lamps.

1. Mechanical interlocking device: Interlocking is achieved internally through mechanical means. When one door is opened, the other door cannot be opened and must be closed before opening the other door.
2. Electronic interlocking device: Integrated circuits, electromagnetic locks, control panels, indicator lights, etc. are used internally to achieve interlocking. When one door is opened, the other door's opening indicator light does not light up, indicating that the door cannot be opened. At the same time, the electromagnetic lock action achieves interlocking. When the door is closed, the electromagnetic lock of the other door starts working, and the indicator light will light up, indicating that the other door can be opened.
