Aramid (NX) Needle Felts

Using the highest quality fiber materials and world-class needling techniques and equipment, HL Filter manufactures a wide range of Aramid (NX) needle felts with high dust-holding capacity and good air permeability. In general Aramid tends to be gradually degraded under hostile flue gas conditions. Consequently filter media made of m-Aramid are frequently processed with an additional protection against acids and hydrolysis.
Bulk Roll Goods: weight, thickness, density, roll width, and roll length are customized at your request.
