  • Patent number: 10213721
    Abstract: An air filter arrangement incorporates a replaceable pleated air filter element which is installed in a rectangular frame. The air filter element is collapsible by flattening together the pleats and placed in an opening in the frame and thereafter stretched apart to extend across the space opposite frame sides and held in that position, by a magnetic element on the end pleat at either end of the air filter element. Sealing pads made of a material similar to the filter element panels are secured to the other two opposite frame sides which engage respective opposite ends of the air filter element for reducing air flow around the pleat ends. A planar lattice restraint is held in a perimeter slot extending around the frame opening to prevent contact of the air filter element and the lattice restraint to minimize the risk of holes being torn in the filter element by such contact.

  • Publication number: 20150027093
    Abstract: Air filter cartridges for use in air cleaner assemblies are described. The air filter cartridges typically comprise a stack of strips of fluted media, having an inlet flow face and an outlet flow face. A projection is provided extending outwardly from adjacent the outlet flow face of the media pack, as a projection supporting a seal arrangement. The seal arrangement is typically rectangular, with four straight and four rounded corners. The projection can be configured with open corners, and in some instances comprises tabs, to facilitate flexing of the projection to accommodate variations in a housing seal surface, with which the cartridge is installed. Air cleaner assemblies and components therefor, using cartridges in accord with the descriptions herein, are described.

  • Patent number: 8940069
    Abstract: An interior air filter for a motor vehicle has a fold pack having a first side. A material with a first leg and a second leg is disposed on the first side. The first leg is attached to the first side and the second leg has a width that is greater than a height of the fold pack. The material strip forms at least partially a head band or a side band of the fold pack. A filter receptacle for the interior air filter has a slanted wall and a mounting and removal opening through which the interior air filter is inserted or removed from the filter receptacle in a mounting and removal direction. The slanted wall extends at an angle that corresponds to an angle defined by the second leg of the material strip of the interior air filter and a contact surface of the filter receptacle.

  • Publication number: 20150013288
    Abstract: Being described are a filter (13) for fluid, particularly an air filter, particularly of an internal combustion engine, particularly of a motor vehicle, a filter housing (11) and at least one filter element (10). The filter housing (11) has at least one inlet (15) and at least one outlet (17) for the fluid. The filter element (10), particularly a flat filter element, comprises an open filter bellows (16) made of a filter medium (18), which has an upstream side (28) and a downstream side (30) for the fluid to be filtered. The filter element (10) is arranged in the filter housing (11) in such a manner that it separates the at least one inlet (15) from the at least one outlet (17). An element axis (14) of the filter element (10) and a housing axis (25) of the filter housing (11) can be aligned parallel or axially to an installation direction (12) of the filter element for installing the filter element (10) into the filter housing.

  • Publication number: 20150013289
    Abstract: A filter element (10) comprises filter bellows (16), in particular open filter bellows made of a filter medium (18), which has an oncoming flow side (28) and an outgoing flow side (30) for the fluid to be filtered. The filter element (10) is disposed in the filter housing (11) in such a way that it separates at least one inlet (15) from at least one outlet (17). An element axis (14) of the filter element (10) and a housing axis (25) of the filter housing (11) may be aligned in parallel with or axially to the installation direction (12) in the filter housing (11) for installing the filter element (10). The filter element (10) has at least one outer support section (38), which protrudes axially beyond the filter bellows (16) on the oncoming flow side (28) or the outgoing flow side (30) with respect to the element axis (14) and protrudes into an axial projection of the oncoming flow side (28) or the outgoing flow side (30) with respect to the element axis (14).

  • Publication number: 20150007537
    Abstract: A flat filter element has a filter medium and a sealing section that seals the flat filter element relative to a filter housing. A support element section is arranged on a circumferential side of the filter medium outside of the sealing section and supports the flat filter element relative to an inner side of the filter housing, wherein the support element section projects past the filter element in at least one direction. The filter housing has a mounting opening through which the flat filter element is inserted into the interior where the flat filter element is arranged such that the inlet is separated from the outlet of the filter housing. A projection arranged on an inner side of the filter housing supports under mechanical tension the support element section of the flat filter element in a mounting position of the flat filter element in the interior.
