Patent number: 8444748Abstract: A V-pack filter includes a frame construction having a first frame structure and a second frame structure. The V-pack filter also includes first and second panel sections mounted in extension between the first and second frame structures. The first panel section has first and second ends. The second panel section has third and fourth ends. The first and third ends have a first distance therebetween while the second and fourth ends have a second distance therebetween. The second distance is generally greater than the first distance. The first and second panel sections and the second frame structure define an air flow aperture. A seal arrangement circumscribes the air flow aperture and projects outwardly from the second frame structure. The first frame structure defines a first receiver indent. Assemblies and methods are also included.Type: GrantFiled: April 26, 2007Date of Patent: May 21, 2013Assignee: Donaldson Company, Inc.Inventors: Gary R. Gillingham, Stan M. Koehler, William J. Krisko, Thomas G. Miller, Winston E. Olson, Fred H. Wahlquist, Ervin P. Fuchs, Eugene D. Wilson
