Needle punched media

High-quality fibers with different melting points are used in an undirected interlocking arrangement. It is made by needle punching and hot air bonding processes. The product has a variety of characteristics such as tight fibre bonding,fracture resistance,corrosion resistance and abrasion resistance.This media is used for pre-filtration or coarse filtration at general HVAC system, with multi-layer structure to block particle, it also could have high dust holding capacity and low pressure drop.Washing with water after containing dust, it can be used for many times to save cost; it does not contain silicon and can resist the influence of chemicals such as chemical solvents and acid smoke.
