Dust Filter Bag
The dust filter bag is used inside the dust collector to filter dust. However, the shape and nature of the dust and the environment of use determine the difference in the fabric. The dust collector bag is the core component responsible for filtering dust in the equipment.

Needle felt dust filter bag is a fine fiber cloth which adopts a non-woven needle punching process and uses fiber staggered and uniform void distribution. The surface of the needle felt produced by polyester staple fiber and polyester crepe is hot rolled, singed or coated. After layer treatment, the surface is smooth and not easy to be blocked by dust. The filter material has large void ratio, good gas permeability, wide application, strong chemical stability, not only filtering normal temperature gas, but also filtering acid. Alkaline corrosive gas, and can filter water, filter oil, is an ideal filter material in the field of normal temperature conditions, liquid-solid separation and other fields. It has the advantages of high voidage, good gas permeability, high dust collection efficiency and long service life. It has a moderate temperature resistance and can reach 150°C in an instant. It is resistant to acid and alkali. Moreover, it has very good wear resistance and is a variety used in felt filter media.
