Customizable Air-shower transfer window for clean room purification workshop




Dynamic pass box is a kind of auxiliary equipment for clean room. It is mainly used to transfer small objects between clean room and non-clean area or between clean rooms with different levels and different pressures. On the one hand, it acts as an air brake to prevent high pressure from being relieved in high-level clean room. On the other hand, it realizes self-purification in the process of re-transmission so as to ensure the self-cleaning of articles entering clean area and reduce cross-contamination caused by objects. The blowing time can be adjusted arbitrarily according to the manual switch, so as to maximize self-purification and energy saving effect.
