P84 dust filter bags are made from high-performance polyimide (P84) fiber, known for its excellent heat resistance and fine fiber structure. The unique trilobal cross-section of P84 fibers provides a large surface area, resulting in superior fine dust collection efficiency and low emission levels.
These filter bags maintain stable performance even under continuous high-temperature operation and in chemically aggressive environments. P84 is widely recognized as one of the best filtration materials for high-temperature dust removal applications.
