Abstract: A filter system for a machine system includes a filter holder assembly having a filter holder, an inner filter connector, and an outer filter connector. The filter holder includes peripheral surfaces each configured with at least one thread section and at least one slot section. The filter system also includes an inner filter attached to the inner filter connector and an outer filter attached to the outer filter connector. Each of the inner filter connector and the outer filter connector includes a peripheral surface configured with at least one thread section and at least one slot section arranged in a key-fit pattern relative to one of the peripheral surfaces of the filter holder. In an example application the concepts may be applied in an intake air system for an engine in an off-highway machine.

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: 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.
