A filter element is provided that is preferably a side entry air filter having an air filter media pack, a housing seal and a frame that has a clamping projection, a pivot projection and/or guide members. The clamping projection can define a non-linear bearing surface that may be chevron shaped to provide for interface and potential alignment benefits. The housing seal may be a wave seal that undulates.

A filter element may include first and second pairs of opposing walls extending along a longitudinal axis of the filter element. The first and second pairs of opposing walls may create a flow passage between an inlet end and an outlet end of the filter element. The filter element may further include filter media configured to separate particulates from air flowing through the flow passage, and a wedge element associated with an exterior surface of at least one of the first pair of opposing walls. The wedge element may be configured to cooperate with an interior surface of a filter housing configured to receive the filter element. Outlet edges of the opposing walls of the first pair of opposing walls may extend at a first oblique angle with respect to the longitudinal axis, and the wedge element may extend at a second oblique angle with respect to the longitudinal axis.

Provided is a construction machine capable of collecting foreign matter into a dust collection pocket and preventing the foreign matter from being scattered. The construction machine includes a cooler, an air passage forming member including a curved section, a dust-proof filter, a cooling fan generating a normal wind for cooling and a reverse wind opposite thereto, a dust collection pocket, and a turning member. The dust collection pocket has an opening and collects foreign matter at a position downstream of the inner wall surface of the outer corner of the curved section. The turning member is turned about a turning axis by the normal wind and the reverse wind, thereby being moved between a close position to close the opening and an open position to open the opening.

A filter assembly includes a support fame, a filter media, and a conditioning device. The filter media is coupled to the support frame. The filter media has a dirty side that receives an air stream and a clean side that outputs the air stream after having been filtered by the filter media. The conditioning device is coupled to the support frame. The conditioning device is positioned downstream of the clean side of the filter media with respect to the air stream and directly contacts the clean side of the filter media.

An air filter device includes an air filter and a filter case having a filter housing for housing the air filter. The filter case has a pipe part enclosing an outer circumference of a second end of a filler pipe. The second end of the filler pipe defines a fuel filler opening and is opposite to a first end of the filler pipe connected to a fuel tank of a vehicle. A distance between the pipe part and the fuel filler opening is less than a distance between the filter housing and the fuel filler opening. The pipe part is configured to be inserted into a fixed member fixed to a vehicle body. The pipe part has a flange that extends radially outward from the pipe part and is spaced apart from the filter housing in an axial direction.

A motorized working apparatus includes a housing having an air inlet, an air guide leading from the air inlet into the housing, and an air filter which is curved hood-shaped outwardly and covers the air inlet of the housing. The air filter includes a filter frame body with a filter-fabric-free air outlet face facing the air inlet of the housing and with a window frame structure protruding over the filter-fabric-free air outlet face and having at least one window region. A filter fabric occupies the at least one window region, and a fixation releasably fixes the filter frame body to the housing. The window frame structure has frame webs which delimit the at least one window region and which protrude relative to the filter fabric towards an air supply side in the at least one window region and include web side edges which run sloping at an obtuse angle relative to adjacent window planes, and/or the fixation includes a pre-fixing clamping holding arrangement and a final fixing holding arrangement which are independent of each other, and/or the window frame structure of the air filter protrudes over the filter-fabric-free air outlet face in the shape of a roof with a triangular cross-sectional form.

A filter element may include first and second pairs of opposing walls extending along a longitudinal axis of the filter element. The first and second pairs of opposing walls may create a flow passage between an inlet end and an outlet end of the filter element. The filter element may further include filter media configured to separate particulates from air flowing through the flow passage, and a wedge element associated with an exterior surface of at least one of the first pair of opposing walls. The wedge element may be configured to cooperate with an interior surface of a filter housing configured to receive the filter element.

A filter assembly for a motor-vehicle air cleaner includes a primary filter, a secondary filter set apart from the primary filter, and a filter frame configured to support the primary filter and the secondary filter. The filter mount is fittable in and removable from a housing of the air cleaner, and includes a divider passing between the main filter and the auxiliary filter, the divider including at least two channels separated by a rib.

An air filter (10) includes an openable filter housing (12) and a filter element (18). The filter housing (12) includes an inlet (26) and an outlet. A filter element (18) with a filter medium (46) is disposed replaceably in the filter housing separating the inlet (26) from the outlet (22). The filter element (18) features on an exterior side facing away from the element interior space (52) on an axial front face relative to the element axis (32) at least one supporting element (58) having at least one supporting lateral surface (60, 61) with at least one cylindrical portion and/or at least one portion with a variable cross-section in the direction of a main axis. The supporting element (58) is supported at least transversely in relation to the element axis (32) with the at least one supporting lateral surface (60, 61) against at least one corresponding support portion (42) on the side of the filter housing (12).

A filter device is disclosed having a round filter element having a filter medium body with an open interior. The filter element is installable into a filter housing having a base filter housing and a housing cover, in which an inflow opening of the cover overlaps against and aligns with an inflow opening of a base housing part such they form a continuous inflow opening. A support mesh cage arranged on the radially outer wall of the annular filter medium body. The filter housing has a longitudinally extended cross-sectional shape in which the inflow opening and an outlet opening are both arranged on the base housing part at opposing sides of the base housing part.
