2. Bag dust collector:
Film-coated filter material is made of polytetrafluoroethylene (PTFE) as a raw material, which is expanded into a microporous film. This film is laminated on a substrate such as glass fiber woven fabric or needle felt with a special process. The surface filtration characteristics of the polytetrafluoroethylene membrane and the spatial structure filtration characteristics of the substrate filter material are provided, which have the advantages of high temperature resistance, high dust removal efficiency, and long service life.
