Publication number: 20230166206Abstract: A filter cartridge for an air cleaner assembly is disclosed. The filter cartridge can include a media pack configured for installation into an air cleaner housing, the media pack extending along a longitudinal axis between opposite inlet and outlet flow ends, the media pack defining an outer perimeter. The filter cartridge can also include a circumferential shell surrounding at least a portion of the media pack outer perimeter. A radial flange extending from the circumferential shell proximate the media pack inlet end can also be provided. The flange can define a plurality of openings that are configured to receive protrusions on a housing body of the air cleaner assembly. The interaction between the protrusions and openings operates to ensure a secure seal between the housing body and the seal member.Type: ApplicationFiled: November 7, 2022Publication date: June 1, 2023Applicant: Donaldson Company, Inc.Inventors: Anthonius Jan-Baptist Maria MOERS, Johnny CRAESSAERTS, Bart CATOOR

Patent number: 11305221Abstract: The present disclosure is directed towards filter elements whose overall length can be adjusted such that the filter element can be installed through an opening in an air cleaner opening having a relatively smaller dimension than the maximum dimension of the filter element. In one aspect, the filter element can include a radial seal member disposed on a positionable coupling element circumscribing at least a portion of a filter medium pack. The filter element has a first axial length when the positionable coupling element is in an extended position and has a second axial length when the positionable coupling element is in a collapsed position, wherein the first axial length is greater than the second axial length. In some examples, the filter element includes two positionable coupling elements.Type: GrantFiled: March 23, 2018Date of Patent: April 19, 2022Assignee: Donaldson Company, Inc.Inventors: Kristof Decoster, Bart Catoor, Mathijs Verstraete
