  • Cleanroom Laminar flow Pass Box

     Laminar flow Pass Box is an auxiliary equipment for clean room, mainly for small objects passing between the clean room and non-clean areas or different pressure, different clean class of clean rooms, one played as an airlock roll to protect high pressure of high clean class level clean room not be released, also achieve self-cleaning effect during transfer process, in order to ensure the articles itself clean to access to clean area, reduce cross-contamination caused by the object ; its blowing leaching time adjusted in accordance with the manual switch that achieved maximum self-purification and energy-saving effect.
