Abstract
The above objectives are accomplished according to the present invention by providing a filter medium for operating environments needing static electricity dissipation to help reduce ignition sources comprising: a substrate of non-woven felt including a polymeric fiber; a conductive scrim having a grid of conductive filaments adjacent to said substrate layer; and, a top layer of non-woven felt including a polymeric fiber and copolymer fiber blend having a melt temperature greater than 100° C. wherein said substrate layer, said conductive scrim and said top layer are manufactured into said filter medium by mechanical web formation.
