By treating the surface resinification treatment, Easily dedusting needle punched filter felt have sooth surface and can improve the air permeability , smooth degree  and reduce the dust adherence, operating resistance.

Futures

1.   Improved cheanability

2.   Low fiber and particle friction of abrasive dusts

3.   Increase in the active filter surface area
