  • Patent number: 11623172
    Abstract: An air filter cartridge includes a coiled media pack with inlet flutes and outlet flutes. The coiled media pack has first and second rounded ends with at least a first straight side and a second side. The coiled media pack has: (i) a length extending along a straight line from a center of the first rounded end to a center of the second rounded end; (ii) a first width between the first straight side and second side; the first width being perpendicular to the length; and (iii) a second width thereacross; the second width being perpendicular to the length. The first width is narrower than the second width.

  • Publication number: 20210308611
    Abstract: A filter element includes a media pack and a gasket member. The gasket member includes first and second gasket regions separated by a channel. The elements are usable in a dust collector having a dirty air inlet, a clean air outlet, and a tubesheet dividing between an unfiltered and a clean air volume. An element is removably mounted and sealed within the tube sheet. At least one projection angled relative to a plane of the tube sheet extends into the channel of the gasket member. A method of servicing a dust collector includes removing a first filter element from the tube sheet in the housing, and then sealing a second filter element against the tube sheet by orienting at least one projection extending from a plane of the tube sheet into a channel defined by a gasket member secured to the second filter element. An axial force is exerted to form a seal between the gasket member and the tube sheet.

  • Publication number: 20110252758
    Abstract: Filters capable of dissipating static charges. One example includes a filter media pack comprising fluted media secured to facing media; the fluted media having cellulose fibers; and the fluted media including an amount of carbon black sufficient to impart a static charge dissipative property thereto. One example includes an air filter cartridge having a filter media pack comprising fluted media secured to facing media; the fluted media comprising cellulose fibers; the fluted media having at least one side coated with a static charge dissipative amount of a metallic coating.
