Abstract: 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.

Abstract: 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.

Abstract: 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.
