Patent number: 11358088Abstract: A filter assembly for an air filter includes a filter element and a sealing member. The filter element has a filter medium and includes an inflow side, an outflow side, and a filter axis extending therethrough from the inflow side to the outflow side. The sealing member surrounds a peripheral edge of the inflow side of the filter element. The sealing member includes an edge protecting portion and a sealing portion. The edge protecting portion includes a side portion extending in a first direction from the peripheral edge of the inflow side along a portion of a side of the filter element. The sealing portion depends from the edge protecting portion and extends axially farther than the side portion of the edge protecting portion in a second direction perpendicular to the first direction. The sealing portion is adapted to engage a housing of the air filter.Type: GrantFiled: April 22, 2021Date of Patent: June 14, 2022Assignee: MANN+HUMMEL GmbHInventor: Michael Englmaier

Patent number: 11344832Abstract: An air filter including a base and a first and second frame element is disclosed. Each frame element is coupled to the base. The frame elements have an oscillating shape having a first portion relatively close to the base and a second portion relatively farther from the base. A filter element generally follows the oscillating shape of the frame elements. An air filter system is also disclosed. The air filter system can include the air filter and an air filter container. The air filter container contains the air filter and directs air through the air filter in a predetermined direction. An air filter is disclosed including a support structure and an oscillating shaped filter element attached to the support structure. The oscillating shape increases the air filter surface area for a given volume.Type: GrantFiled: June 9, 2017Date of Patent: May 31, 2022Assignee: K&N Engineering, Inc.Inventors: Steve Williams, Jere James Wall

Patent number: 11123675Abstract: A filtering media member is formed of porous material. A first edge portion includes an upstream edge. A second edge portion is spaced apart from the first edge portion and includes a downstream edge. A main portion is arranged intermediate the first and second edge portions. The edge portions and the main portion together define a generally planar first surface. A plurality of channels is formed on the first surface. Each of the channels is arranged adjacent to one another and has a length. Each of the channels includes an inlet disposed proximate to the first edge portion so that, in use, fluid flows from the upstream edge through the inlet to the respective channel, and each of the channels has a width in the lateral direction that decreases across its length so that the channels taper between the first and second edge portions.Type: GrantFiled: February 8, 2017Date of Patent: September 21, 2021Assignee: DCL International Inc.Inventors: Zbigniew Sarna, Haiqing Liu, John P. Muter, Shazam S. Williams

Patent number: 11097217Abstract: An air filter assembly includes a filter element having at least one variable dimension, and a frame for engaging and supporting the filter element. The frame may include a plurality of linear segments forming a rectangular configuration, and a plurality of clips for connecting the linear segments together at corners thereof. The linear segments may be L-channel segments, C-channel segments, or may be of other form. Clips may be used for connecting the linear segments together at the corners. The filter element may have a pattern of creases or fold lines to facilitate folding thereof from an expanded configuration to a reduced configuration. A grate may be included for spanning an area bounded by the frame to support the filter element. The grate may have multiple arms and a central hub. An edge treatment may form a seal between the filter element and the frame.Type: GrantFiled: September 13, 2019Date of Patent: August 24, 2021Assignee: Second Nature Brands, Inc.Inventors: Kevin James Barry, Thaddeus Worth Tarkington, Aly Khalifa

Patent number: 11033846Abstract: A filter cartridge is provided. The filter cartridge includes a filter element comprising a filter media, and the filter element extends between an inlet face and an outlet face. The filter element defines a periphery surrounding the filter media. The filter cartridge also includes a border frame including a plurality of side panels, and the side panels are independently molded-in-place along the periphery of the filter element. Adjacent members of the side panels are joined together along a plurality of mold interface seams, and the mold interface seams are spaced around the periphery. The plurality of side panels are embedded in and seal the periphery of the filter element such that fluid flow inside the border frame is directed to pass through the filter media for filtering in order to pass from the inlet face to the outlet face.Type: GrantFiled: February 7, 2017Date of Patent: June 15, 2021Assignee: Parker-Hannifin CorporationInventors: Daniel R. Haas, LaMonte A. Crabtree, Hershel E. Fancher

Patent number: 11014113Abstract: A filter for industrial coating filtration systems. The filter has a housing made up of a peripheral wall extending around the periphery. The housing is preferably made of a suitably rigid material. A preferably rigid support backing is mounted within the housing. The support backing has a planar configuration with openings formed through it so that gas can flow through without substantial resistance. The preferably planar sheet of which the support backing is made is pleated. The pleated support backing defines a series of panels, each of which is angled to a next adjacent panel. Filtration media is mounted to the support backing, end caps are attached to the ends of the support backing to maintain the pleated configuration, and the assembly is inserted into the housing, which can have end flaps to seal using tape or adhesive.Type: GrantFiled: March 3, 2020Date of Patent: May 25, 2021Assignee: Columbus Industries, Inc.Inventors: Mounir B.
