Patent number: 11623172Abstract: 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.Type: GrantFiled: July 1, 2020Date of Patent: April 11, 2023Assignee: Donaldson Company, Inc.Inventors: Thomas D.

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
