A filter assembly that includes a filter housing with a housing interlocking feature, a filter cover with a filter cover interlocking feature, and a filter element with a filter element interlocking feature is disclosed. The filter element is positionable within the filter housing, and the filter cover is attachable to a top portion of at least one of the filter element and the filter housing. The housing interlocking feature, the filter cover interlocking feature, and the filter element interlocking feature are interlockable with each other and extend in a nonplanar configuration along at least one side of the filter element when the filter housing, the filter cover, and the filter element are assembled together.

A connection arrangement for fixing a lid to a filter housing and to a filter element, by which an insertion opening in the filter housing can be closed, includes a holding element on the filter element and a locking element on the lid. The holding element can be fixed by a contact surface for contacting the locking element in a recess of the filter housing. The holding element has a latching geometry with which it can be latched in the recess of the filter housing. The locking element is a shaft with a bolt rod and a handle part. The shaft is guided through the lid such that the lid and the filter element in the latching position can, by the bolt rod and a contact surface formed as a ramp on the holding element, which engage with one another by turning the locking element, be spanned against each other.

A vehicle body structure includes a wall and a removable panel. The wall has a first surface and a second surface opposite the first surface. The wall defines a vent opening with a peripheral edge extending between the first surface and the second surface. The wall includes an air vent structure open to the vent opening. The removable panel has a trim surface and an attachment surface with a plurality of air vent slots extending from the attachment surface to the trim surface. The attachment surface has a retaining structure configured to retain an air filter along the attachment surface and an attachment structure configured to attach to the wall covering the vent opening with the retaining structure extending at least partially within the air vent structure.

A filter element for an air filter of a motor vehicle includes a frame part which surrounds a filter material of the filter element. The filter element is insertable into a receiving space which is provided by a housing of the air filter. The filter element has a holding element which is movable from an initial position into a functional position by inserting the filter element in the receiving space. In the functional position, a fastening element can be fixed to the holding element. The fastening element is configured for securing a cover element, which is used to close an insertion opening of the receiving space, to the housing.

An air cleaner may include an electrostatic air cleaner including: an air cleaner casing; an air cleaner main body; and an air cleaner return grille cover which is coupled to the air cleaner casing, wherein the air cleaner main body may include: a filter unit which has a size greater than a predetermined particle size; a dust collector unit which secondarily filters out dust, which passes through the filter unit and has a size equal to or smaller than the predetermined particle size, by collecting the dust on an electrode plate by generating a high-tension arc; a converter unit which generates the high-tension arc on the dust collector unit; and a sensor unit which measures concentration of the dust having a size equal to or smaller than the predetermined particle size to operate the dust collector unit and the converter unit.

An air box and methods are provided for communicating an airstream through an air filter to an air intake duct of an internal combustion engine of a vehicle. The air box generally transports air received by way of air inlet ports that mate with aerodynamic elements of the vehicle. The air is received through a conduit to an air intake duct of the engine. The air box comprises an enclosure that is formed in a substantially rigid/solid form. A substantially transparent inspection region is disposed on a surface of the enclosure so that the air filter may be viewed and potentially accessed if desired.

An air supply unit, in particular for a heating, ventilation or air-conditioning unit in particular of a motor vehicle, an includes at least one air inlet, an air filter unit and a blower unit and an air outlet, wherein the filter unit comprises a filter housing in which a filter support is provided to support a filter element, which is located within the filter housing and which is supported within the filter housing by the filter support, wherein the filter support comprises an air guide for guiding air.

An air filter for a ventilation system of a motor vehicle may include a plate-shaped filter body of a folded filter material and at least one sealing strip secured to a lateral edge of the filter body. Adjacent folds of the filter body may be connected to one another via a seam, may follow one another in a longitudinal filter direction, and may extend in a transverse filter direction. The at least one sealing strip may have at least one removal opening penetrating the at least one sealing strip. At least one removal nozzle for removing air flowing through the air filter may be securable to the at least one removal opening.

A filter element for filtering a fluid has one or more filter bellows with a specified raw side and a specified clean side oppositely positioned relative to the specified raw side. The filter bellows has a filter medium that is folded along fold edges in a zigzag shape to folds, wherein the folds extend between oppositely positioned end edges of the at least one filter bellows, wherein the filter bellows has parallel extending end edge faces at oppositely positioned end faces. At least one pre-separator embodied as a flat mat is arranged at the raw side of the filter bellows. A frame is injection-molded from plastic material around the filter bellows and seals the end edge faces. The pre-separator is fastened to the raw side with fastening elements arranged at the frame. A filter system with a filter housing is provided with such a filter element.

A filter assembly that includes a filter housing with a housing interlocking feature, a filter cover with a filter cover interlocking feature, and a filter element with a filter element interlocking feature is disclosed. The filter element is positionable within the filter housing, and the filter cover is attachable to a top portion of at least one of the filter element and the filter housing. The housing interlocking feature, the filter cover interlocking feature, and the filter element interlocking feature are interlockable with each other and extend in a nonplanar configuration along at least one side of the filter element when the filter housing, the filter cover, and the filter element are assembled together.
