This membrane is made of glass fibers as main raw material by wet process . Characterized by uniform fiber distribution, high dust holding capacity, low resistance and high strength, it is an ideal material for air filtration. Depending on the filtering efficiency, the products are divided into three series(ASHRAE, HEPA and ULPA).
Used for primary, medium and high efficiency air conditioning systems in medical, electronic, food and textile industries, etc. Glass Fiber Air Filtration Membrane ASHRAE: Mainly used for common air conditioner, gas turbine and air compressor. Glass Fiber Air Filtration Membrane HEPA: Mainly used for 104 grade~105 grade clean room, operation platform, nuclear power plant, high-grade household dust collector, air cleaner and gas mask etc. Glass Fiber Air Filtration Membrane ULPA: Mainly used for chip plant,100grade,10grade,1grade clean room etc.
