Patent number: 11654385Abstract: Referring to the figures generally, a rotating filter cartridge includes a first endcap, a second endcap, and a filter media. The filter media is positioned between the first endcap and the second endcap. The filter media creates a mechanical seal between at least one of the first endcap or the second endcap during rotation of the rotating filter cartridge without the use of a potting material. In at least one embodiment, the rotating filter cartridge further includes a body secured to the first endcap and the second endcap. At least one of the first endcap or the second endcap, and the body, may form a pocket that radially pinches the filter media to form the mechanical seal.Type: GrantFiled: September 20, 2016Date of Patent: May 23, 2023Assignee: CUMMINS FILTRATION IP, INCInventors: Himani Deshpande, Christopher E. Holm, Anthony Barreteau, Chirag D Parikh, Gérard Malgorn, Alain Olier, Bradley A Smith, Benjamin L Scheckel, Lee A. Peck, Brian W. Schwandt, Ken Tofsland

Publication number: 20190046911Abstract: Referring to the figures generally, rotating filter cartridges (e.g., a rotating coalescers) for a rotating filtration system (e.g., rotating coalescer crankcase ventilation systems) are described. The described filter cartridges use mechanically created seals to seal the filter media to the endcaps of the filter cartridges. Accordingly, the described filter cartridges eliminate the need to use a potting or embedding material during manufacturing of the filter cartridge, thereby eliminating the costs and potential manufacturing defects associated with the potting or embedding material and process.Type: ApplicationFiled: September 20, 2016Publication date: February 14, 2019Applicant: Cummins Filtration IP, Inc.Inventors: Himani Deshpande, Christopher E. Holm, Anthony Barreteau, Chirag D. Parikh, Gérard Malgorn, Alain Olier, Bradley A. Smith, Benjamin L. Scheckel, Lee A. Peck, Brian W. Schwandt, Ken Tofsland
