Anti-static Felt Filter Media

Anti-static needle felts are used when static dissipation is required. HL Filter offers three types of anti-static needle felts:
(1) Stainless steel scrim supported felt (grid/matrix or stripe/line)
(2) Stainless steel fiber blend felt
(3) Epitropic fiber blend felt

Bulk Roll Goods: weight, thickness, density, roll width, and roll length are customized at your request.

Has media characteristics of the blended fibers

Excellent Anti-Abrasion

Anti-static filter media (use when static dissipation is required)
Stainless steel scrim supported felt A woven scrim comprised partially of stainless steel yarns
Stainless steel fiber blend felt Use of stainless steel fibers blended with standard fibers
Epitropic fiber blend felt A blend of standard and epitropic (carbonized) fibers

Continuous operating temperature depending on the blended fibers
