Needle felt is a kind of non-woven filter fabric specially used for dust collector filter bags. It is a major filter material for industrial air filtration and dust removal. The needle felt is made of randomly arranged fibers needle punched on the scrim fabric, after that the fibers are close-knitted to form a tortuous three-dimensional stereo-structure, which is different from the traditional woven filter cloth composed of warp and weft yarns. It makes dust particles adhere to the surface of the filter material and form an initial layer of dust ( Filter cake), with the remarkable characteristics of small pore size, high filtration efficiency and low air resistance, greater air permeability and excellent dust particle capture.

Bag filters are in general frequently used for dust removal in industrial applications. We make filter bags to fit most styles and types of bag houses and other dust collection systems. Filter bags come in a wide range of fabrics, coatings, finishes, sizes and configurations.Medias are available in various fabric weights and treatments such as singed, glazed, PTFE membrane, anti-static, acid resistant and more.
