| 主权项 | 1. A filter medium for operating environments needing static electricity dissipation to help reduce ignition sources comprising: a substrate layer of non-woven felt including a polymeric fiber; a conductive scrim having a grid of conductive filaments adjacent to said substrate layer; 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; and, wherein the filter medium includes the physical property of having an electrical resistance less than 25,000 ohms when 250V is applied to said filter medium. | ||
