The glass fiber needle felt dust bag is suitable for using in pulse cleaning and high speed reverse blow bag filter. After being tested for a long time by high temperature and corrosive medium, it has excellent performance, effectively control dust pollution and recover valuable fine particle products.

Glass fiber needle felt dust bag is a new type of high temperature filter material with reasonable structure and excellent performance. It is made of 100% glass fiber as raw material and needle punched into felt. Glass fiber mat dust bag glass fabric not only has high temperature resistance, corrosion resistance, dimensional stability, elongation and contraction rate of small, has the advantages of high strength, but the fiber mat layer bearing single fiber, three-dimensional porous structure, high porosity, gas filter, it is a kind of high temperature filter material with high speed and high efficiency. Compared with other high temperature resistant chemical fiber felt, glass fiber needle felt dust bag has special advantages such as low price, low running resistance, high filtration precision and high temperature resistance. It is suitable for high temperature fume filtration in steel, metallurgy, carbon black, power generation, cement, chemical industry and other industries.
