Dust filter bag
Dust filter bag
Dust filter bag features good ventilation performance, high dust removal efficiency. It has certain acid resistance, alkali resistance, and heat resistance. In the process of weaving, multilateral napping method is adopted, the fabric thickness is improved, the dust removal efficiency is very good, and the dust removal rate can reach 99.999%. Adopt dacron short fiber or long fiber as raw material, the service life is commonly 4-6 times of glass fiber fabric.
