Needle felt filter bags have the advantages of high void space, good air permeability, high dust collection efficiency, and long service life. Its moderate temperature rating, instant up to 150 °C, moderate acid and alkali resistance, and very good wear resistance. Acupuncture felt filter bag (dust removal bag) is a key part of the operation process of the bag filter. The fabric and design of the needle filter bag filter are as high as possible for efficient filtration, easy dust stripping and durability.
