What are the common dust collector cartridge materials and what conditions do they suit?

Common industrial cartridge materials and their applications: 1) Standard polyester fiber — regular dry dust (grinding, cutting, wood dust) at ambient temperature (≤120°C), cost-effective; 2) PTFE-membrane polyester — fine, oily and slightly sticky dust; the membrane prevents dust adhesion and allows thorough cleaning, with filtration precision down to 0.3μm; 3) Anti-static polyester — flammable and explosive dust such as coal, aluminum and magnesium powder, eliminating static buildup hazards; 4) High-temperature media — for hot flue gas at 120–240°C.
