Publication number: 20210308611Abstract: 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.Type: ApplicationFiled: March 12, 2021Publication date: October 7, 2021Inventors: Thomas D. Raether, Brian Zauner, Jim C. Rothman

Patent number: 8460442Abstract: Fluted filter media includes filter material having a plurality of flutes formed therein having alternating ends of adjacent flutes closed to force fluid through filter material. A first embodiment of the filter media includes tapered flutes which have the open ends of the flutes larger in cross-section than the closed flutes, wherein the upstream open flutes converge toward the downstream end and the upstream closed end flutes diverge toward the downstream end. A second embodiment includes filter media which is asymmetric formed with dissimilar upstream and downstream flute cross-sections with larger flute openings to the upstream side of the filter. A third embodiment includes filter media with an upstream edge crushed to improve flow at the upstream edge. A fourth embodiment includes filter media with the upstream sealing material recessed from the upstream edge for reducing effects from blockages at the upstream edge of the filter.Type: GrantFiled: August 21, 2012Date of Patent: June 11, 2013Assignee: Donaldson Company, Inc.Inventors: Wayne M.
