The glass fiber paint resistance net is made of glass long fiber and made by non – weaving method. Good fiber strength, good elasticity, good dust collection efficiency, low resistance. The gradual density structure can block dust particles at different density levels according to dust particle size and has large dust holding capacity. Under a certain wind speed, it can maintain the original shape, increase the life of the filter and reduce the replacement cost. Good temperature resistance, up to 280 ℃; strong moisture resistance, can reach 100%RH relative temperature. It uses color to distinguish dust-catching direction, and the air inlet side is white and the air outlet side is green. It can be equipped with galvanized steel plate frame or an aluminum alloy frame can also be equipped with a metal back network, and can effectively support the filter to withstand a large amount of wind and does not deform.
