Patent number: 7090711Abstract: 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: March 29, 2005Date of Patent: August 15, 2006Assignee: 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

Patent number: 7074250Abstract: An air filtration unit for use in a work environment includes a housing disposed with an air filtration system and light source. The housing includes a handle and corner caps to prevent damage and provide stability. The air filtration system draws air into the housing, via a blower, through a first and second inlet gate, the air is at least partially filtered by a first and second filter assembly, which provide a two stage filtering, and then the at least partially filtered air is blown through an exhaust conduit back out into the work environment.Type: GrantFiled: December 19, 2003Date of Patent: July 11, 2006Assignee: Black & Decker Inc.Inventors: Todd Chipner, Mark A. Etter, Angela D. Shelton, Leslie D. Gist, John C. Smith, Charles Chen

Patent number: 7041146Abstract: An air cleaner for a vehicular engine includes a pre-filter which receives air flow containing particulates and a primary filter which receives the air from the pre-filter. The pre-filter removes a first proportion of particulates from the air, and the primary filter removes a second proportion of particulates from the air. The pre-filter is separately serviceable from the primary filter.Type: GrantFiled: September 10, 2003Date of Patent: May 9, 2006Assignee: Visteon Global Technologies, Inc.Inventors: Neville Jimmy Bugli, Gregory Scott Green, Jeffry Marvin Leffel

Patent number: 6974491Abstract: A cartridge locking device (10) for holding a filter media (14) in a plenum (12) in which an actuator (112) movable between a first position and a second position connects to a lever member (122) inwardly of the plenum (12) that moves between a position bearing on the filter media (14) to a spaced-apart position for replacing the filter media (14), the locking device (10) operable from the holding position to the spaced-apart position without opening the plenum (12), thereby reducing the time for the plenum (12) to be open during replacement operations. A method of locking and releasing a filter (14) for filter (14) change out is disclosed.Type: GrantFiled: August 1, 2003Date of Patent: December 13, 2005Inventor: Stephen P. Kendall
