Technical Characteristics of HUALONG Needle Punched Filter Felt:

a. Singeing and calendaring treatment----not only improve the cleaning performance accuracy and low dropout performance of the filter material.

b. Anti-static treatment---

Anti-static filter material which is the fiber or fiber nixed with conductive fibers ( including the binary conductive

fiber, carbon fiber or stainless steel conductive fiber), so that the filter material has conductive properties.

c. Water and oil proof Treatment---

can prevent and mitigate paste bags of phenomenon.

d. Easily dedusting treatment---it has good cleaning performance, air permeability, and can work long hours in a high filtered wind speed.

e. PTFE with the membrane treatment---has high filtering accuracy, smooth surface, no adhesion of dust, easily dedusting and the dust does not penetrate into

the filter inside to achieve the surface.

f. ZMPS Microfiber treatment---high filtration efficiency; many kinds of surface treatment to meet the needs of different operating conditions; decrease

the investment and cost.
