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.
