Claims14
A filter element comprising a cartridge filter of granular adsorbents or spiral wound membrane element, having an outer surface and a foam seal incorporated as an integral part of the outer surface.
A filter housing adapted for receiving a corresponding filter element, wherein the housing includes an inner surface and a foam seal incorporated as an integral part of the inner surface, wherein the seal is adapted to contact with an outer surface of a corresponding filter element.
A filter element comprising a cartridge filter of granule adsorbents or spiral wound membrane element having an outer surface, a seal positioned about at least a portion of the outer surface, and a shrink wrap material covering the seal and outer surface of the filter element.
A filter element having an cylindrical outer surface extending between two ends, a seal comprising a single band disposed about the outer surface of the filter element and which extends between the ends of the filter element and along substantially its entire length, and a shrink wrap material disposed over the seal.
A filter housing adapted for receiving a cylindrically shaped filter element, wherein the housing includes a corresponding cylindrically shaped inner surface wherein the improvement comprises a foam seal incorporated as an integral part of the inner surface, wherein the seal is adapted to contact with an outer surface of the corresponding filter element.
