Easy-cleaning needle punched felt is a type of PET which treated by special process. It has smooth surface, so when dust collector reverse blowing the dust on the surface very easy to clean up, then improve the filtering effective of dust collector.

PTFE membrane felt is a kind of filter material, which is coated with PTFE membrane on its surface. The surface of PTFE membrane felt is smooth and anti-chemistry. It can stop dusts getting into inner, and surface filter can be realized. Compared with normal material, PTFE membrane felt has higher peel strength and air permeability, lower pressure drop, and efficiently prevents ultrafine dust measured in microns. Filtration efficiency is up to 99.99%.

Anti-static needle punched felt is a normal temperature anti-static electricity filter material special conductible fiber been added into the PET fabric, that will prevent accumulation of charge then the felt could anti-static electricity. This product applied in coal dust, chemical dust, high concentration flammable and explosive dust flue gas filtering. There are two types of the product, Bar shape and Hybrid.

Oil &water repellent needle punched felt. It is made based on normal PET felt, treated by special waterproof process make the felt has good oil & water resistance performance. The product applied for heavy humidity, oily flue gas cleaning. It prevent dew better and not easy to wet bag. Prolong the service life of filter bag effectively.
