High efficiency filter device HEPA Return or Exhaust Air Box
High-efficiency return air box is an exhaust device for negative pressure clean rooms. It is used for return air filtration in negative pressure workshops to isolate toxic, harmful, carcinogenic, radioactive and biologically hazardous dust and gas to prevent indoor harmful substances from being discharged into the return air exhaust system. It is mainly used in pharmaceutical, food, biological laboratories, hospitals and other fields.
Product Description
● The polluted gas generated by production activities in the clean room is called a high-efficiency return air outlet when the purified gas is connected to the return air duct, and is called a high-efficiency exhaust when it is connected to the exhaust duct. High-efficiency return air outlet/exhaust outlet is mainly composed of a box, a high-efficiency filter, a return/exhaust panel, etc.
Technical features of high-efficiency return air box/exhaust air box
● The box body is seamlessly welded to ensure good air tightness.
● The return/exhaust air panel is available in various forms: full-hole panel, shutter panel, uniform flow membrane panel.
● The return and exhaust air panel is installed and fixed with a special structure, which is convenient for sensing and invisible installation. It is beautiful and easy to clean.
● The differential pressure gauge monitors the resistance of the high-efficiency filter in real time.
● In-situ automatic scanning for leak detection and in-situ online disinfection.
● Optional configuration of a series of sterilization lamps, air volume control valves, automatic scanning devices, etc.
● The filter efficiency level can be selected according to the indoor cleanliness requirements.
Product advantages
