Pass Box
I. Product Introduction
A Pass Box is an enclosed transfer chamber designed for safe material movement between cleanroom zones of different classification levels (e.g., ISO Class 5 to ISO Class 8), preventing cross-contamination during the process.
Outer frame and inner tank:stainless steel or cold plate paint.Electronic/mechanical interlocking device to prevent doors on both sides from opening at the same time.There are door opening signal lights on both sides of the box,so you can know the opening status of the opposite door.Ultraviolet germicidal lamp can be installed.
