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.
Needle felt filter bag is the most commonly used dust bag product in dust bag. Main application industries: cement raw material grinding, packaging and transportation, smelting plant (sintering machine, continuous casting), mine (collecting limestone powder), non-ferrous amount plant ( Alumina transportation, electrolytic aluminum), furniture factory (polishing workshop), grain processing, pharmaceutical and other industries dust collection. This dust filter has high strength, good elastic recovery performance, stable fabric size, good abrasion resistance, large voidage, good air permeability, long service life, good dust removal effect, and good mechanical properties at room temperature (less than 130°C). Performance and acid and alkali resistance. Due to the low price of polyester, polyester needle felt is the most cost-effective filter media at low temperatures.
