F bag filter media is made of a unique non-shedding, water, and man-made fibers constituting the surface layer and the inner stratification. Rough first layer captures larger and heavier particles in the air, a second layer of reinforced fine filter stability and prevent small dust floating in the air, this dual-media design ensures a low initial resistance and high dust holding capacity, and extend the life of the filter. Bag filters for industrial and residential ventilation systems common air filtration varieties, by the use of different points nonwoven filter bag, bag of glass fiber, and chemical fiber three. Colorimetric average atmospheric dust filtration efficiency: 45%, 65%, 85%, 95%, 98%. Its filtration efficiency rating were F5, F6, F7, F8, F9 Overview: fiberglass bag filter meltblown filter ultra-fine glass fiber, frame optional aluminum, stainless steel, galvanized steel frame, optimized "V "bag-shaped structure, especially for high temperature, high winds baking system air filter. Characteristics: temperature 100 ℃ ~ 170 ℃. Filter area, dust holding capacity, low resistance, ventilation capacity, high filtration precision, the frame and the support frame can be reused. Filtration efficiency (filter) F5-F8 optional Application: specifically designed for high operating temperature, clean and high air volume of air in general ventilation and air conditioning system purification.
