The Interlocked Pass Box is essential for material transfer between cleanroom zones of different cleanliness classifications. Its electronic or mechanical interlocking system prevents both doors from opening simultaneously, avoiding cross-contamination. Can be equipped with HEPA filtration and optional UV sterilization, it ensures safe and clean transfer processes, widely used in pharmaceuticals, biotechnology, and electronics.
Introduction:
The Interlocked Pass Box is an auxiliary equipment used in cleanrooms. It is mainly used for transferring small items between clean areas, as well as between non-clean areas and clean areas, so as to reduce the number of times the cleanroom door is opened and minimize contamination in the clean area. Pass-through boxes are widely used in micro-technology, biological laboratories, pharmaceutical factories, hospitals, food processing plants, LCD manufacturing, electronics factories, and all other places that require air purification.
