Publication number: 20220274041Abstract: A filter element having a filter media pack with an inlet end, outlet end, and outer periphery extending therebetween. The inlet and outlet ends are separated along an axis. The outer periphery includes a first pair of opposed sides between the inlet and outlet ends, and a second pair of opposed sides extending transversely between the first pair of opposed sides. A frame supports the outer periphery, having opposing first frame side segments, and a second frame segment. Each first frame side segment includes a pair of guide projections extending along respective first sides. The guide projections are spaced apart from one another from a broad end at one second side, to a narrow end at the other second side, and arranged to receive axial forces received within a housing having complementary engagement surfaces. A housing seal is supported along one guide projection, sealing against the complementary engagement surfaces.Type: ApplicationFiled: February 3, 2022Publication date: September 1, 2022Applicant: Parker-Hannifin CorporationInventors: James R.

Patent number: 7909954Abstract: A method and apparatus are provided, for forming a filter element including a media pack in the form of a coiled fluted filter media, by winding the web of fluted filter media around a pair of tools of a mandrel. The tools engage the sides of the filter media. The tools define a major to provide the media pack with a oblong or elongated shape. The web may be fed at constant linear speed, and/or a motor may be controlled in a manner to provide constant driving torque to maintain a constant tension on the web. The winding apparatus and methods may include apparatus or methods to modify the feed path of the web to adjust the tension of the web as it is being wound. Further, the coiled media packs can be fixtured to prevent relaxation. A method may form various shaped media packs with the same apparatus.Type: GrantFiled: July 9, 2007Date of Patent: March 22, 2011Assignee: Baldwin Filters, Inc.Inventors: Stan Johnston, Brian T.

Patent number: 6447567Abstract: An air filter element having end caps molded of foam material, and in which one of the foam end caps also employs the foam material as a radial seal gasket. Tubular inner and outer liners support a tubular filter element. The first ends are molded in a closed urethane end cap sealing one end of the filter element. The other end is molded to provide an open end cap in the form of an annular ring which encases the filter element and the liners, and provides a radial seal gasket. A substantially rigid plastic ring has a base embedded in the open end cap annular ring, and an upstanding flange which carries the radial seal gasket.Type: GrantFiled: May 14, 2001Date of Patent: September 10, 2002Assignee: Baldwin Filters, Inc.Inventor: Brian T.
