Patent number: 10953356Abstract: Disclosed is a composite filter media. The composite filter media is formed from multiple layers of media material including a nanofiber media layer, where the layers are laminated, bound, or otherwise composited to each other. The composite filter media can comprise at least one nanofiber layer comprising polymeric media material having a geometric mean fiber diameter of about 100 nm to 1 ?m, and fibers configured in a gradient such that ratio of the geometric mean diameter of fibers at the upstream face of the nano fiber layer to the geometric mean diameter of fibers at the downstream face of the nano fiber layer is about 1.1 to 2.8, preferably about 1.2 to 2.4.Type: GrantFiled: December 16, 2019Date of Patent: March 23, 2021Assignee: CUMMINS FILTRATION IP, INC.Inventors: William C. Haberkamp, Eric A. Janikowski, Barry Mark Verdegan, Christopher E. Holm, Huanling Liu, Kyle Ellison, Mark T. Wieczorek

Patent number: 10688430Abstract: Cleanable filters and methods of cleaning filters are described in the present application. The cleanable air filter includes a housing and a filter element installed in the housing. The filter element is configured to filter an operating fluid in a given application. The filter element is cleanable in-situ in the installed condition in the housing. The cleanable air filter further includes a cleaning fluid applicator configured to apply a cleaning fluid to the filter element while the filter element is in the installed condition in the housing such that the filter element is cleanable without being removed from the filter housing.Type: GrantFiled: June 11, 2019Date of Patent: June 23, 2020Assignee: CUMMINS FILTRATION IP, INC.Inventors: Mark V. Holzmann, Robert A. Bannister, Budi Antony, Scott W. Schwartz, Brian W. Schwandt, Steven R. Sankbeil, Christopher E. Holm, Eric A. Janikowski, Scott G. Manke
