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.

Filter element and air cleaner assembly

A filtration device may include an adapter, a filter element, and a housing. The adapter may include a collar having an upper rim and a lower rim, a plurality of locking tabs extending from the upper rim, and a plurality of snap members extending from the lower rim. The filter element may include a casing and a plurality of receptacles connected to and arranged around a first outer surface of the casing. The plurality of receptacles are configured to receive the plurality of locking tabs. The housing, which is configured to receive the filter element, includes a shell and a plurality of ramp members that are connected to a second outer surface of the shell. The plurality of ramp members are configure to engage the plurality of snap members.

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.

A filtration device may include a filter element and a housing that is configured to receive the filter element. The filter element may include a casing having a first outer surface and a flange connected to the first outer surface. The flange may include a plurality of snap members. A snap member, of the plurality of snap members, may include a fulcrum projecting from the flange and a lever mounted on the fulcrum. The housing may include a shell having a second outer surface and a plurality of ramp members. The plurality of ramp members may be fixedly connected to the second outer surface and may be configured to engage the plurality of snap members of the filter element. A ramp member, of the plurality of ramp members, may include an angled surface that extends from the second outer surface at an acute angle relative to the second outer surface.

An air filter subassembly includes a filter element with a pre-cleaner tube member that is snapped onto the filter element.

Air filter element with pre-cleaning tubes

A precleaner system for an air intake system. The precleaner system includes precleaners each having flow paths that induce a rotation to air flow and separate out particulate matter. The particulate matter is ejected from an outlet port in each of the flow paths and out of a dust ejector. The precleaned air is collected into a plenum from each of the precleaners. The precleaned air can flow from the plenum to a precleaner system outlet and the precleaned air can be received by an air intake system. A cover can be used to block air flow through one of the precleaners to tune the precleaner system to the desired airflow.

Precleaner system

A stand-alone air filter assembly has a unitary molded plastic preform shell, with the preform shell including an inlet section, an outlet section, and a hose connection section integral with a downstream end of the outlet section. A filter media pack including a fluted filter media member is fitted inside the inlet section of the preform shell through which unfiltered air enters the air filter assembly. The outlet section of the preform shell through which filtered air leaves the air filter assembly converges from a larger, first cross-sectional area of the inlet section to a smaller, second cross-sectional area at the downstream end of the outlet section, and the outlet section includes one or more sensor ports that are each configured to support a sensor for measuring a characteristic of the filtered air leaving the air filter assembly. The hose connection section includes an annular hose bead interface formed around an outer circumference thereof for sealing engagement with a hose fluidly coupling the air filter assembly to an air intake on an engine.

An apparatus for partially blocking airflow in a precleaner for an internal combustion engine may include a stationary barrier configured to be mounted in a precleaner. The apparatus may further include a movable barrier coupled to the stationary barrier and configured to move between an open position and a closed position in response to changes in an air flow rate through the precleaner. When the air flow rate through the precleaner reaches a threshold air flow rate, the movable barrier may move from the closed position toward the open position, and when the air flow rate through the precleaner drops below the threshold air flow rate, the movable barrier may move from the open position toward the closed position.

Apparatus for air precleaner and precleaner

An air filter assembly for a machine is disclosed. The air filter may have a filter medium, and a side wall connected to the filter medium on a first side of the filter medium. The side wall may have a first engagement feature and a second engagement feature. At least one of the first engagement feature and the second engagement feature may project from the side wall. The first engagement feature and the second engagement feature may be configured to slidingly engage a filter housing.

Air filter assembly for a machine

A casting for a housing for a flexible, configurable power converter is disclosed. The housing includes a power compartment that is configured to accept a heat sink in either of two orientations. The configurable nature of the power converter allows the same power convertible package to be used in a number of applications without having to incur the cost of developing a new power converter package.
