A Pass Box is one kind of facilities, which located on partition walls of clean room and its function is to buffer the area for transferring goods between inside and outside of clean room. This is done in order to prevent any disturbance of airflow and air pressure in clean room, which is caused by the door opening for goods transfer. Furthermore, it can reduce the time for operators moving in and out, to isolate and prevent any dust contamination. Which is why we have one interlock guard system controlling the inlet and the outlet of Pass Box so that they cannot be opened at the same time, in order to prevent the cross contamination.
Our Pass Box range has been benchmarked for its qualitative and quantitative parameters.
