Also provided is a filter housing having an inner housing space adapted to receive a tubular filter element, the filter housing having an inlet, a first outlet located in a first end of the filter housing, and a second outlet located in a second end of the filter housing, wherein the second end is located opposite to the first end in relation to the inner housing space.

Rotating coalescer elements that maximize the radial-projected separation surface area in a given (rotating) cylindrical volume, where flow to be cleaned is passing axially upward or downward through a separating media of the rotating coalescer element. Various example package assemblies are provided with various types of rotating configurations including cylindrical coiled media packs, frustum coiled media packs, concentric cylinders, coiled metal or polymer films with and without perforations, and/or alternating layers of different materials. The described rotating coalescers may be driven by hydraulic turbine, electric motor, belt, gear or by mounting on rotating machine components, such as rotating engine shafts or connected components.

An air filter element includes a filter arrangement, an elbow, and a filter element seal member. The filter arrangement includes a filter media pack having a dirty air inlet and a clean air outlet, wherein air flowing through the clean air outlet flows in a first axial direction and the clean air outlet defines a filter arrangement cross sectional area. The elbow has a first end constructed to extend from the filter arrangement clean air outlet, a second end wherein air flowing through the second end flows in a second axial direction, and an air flow enclosure extending from the elbow first end to the elbow second end. The air flow enclosure includes an air deflector constructed to direct air from the first axial direction to the second axial direction, wherein the second axial direction is different from the first axial direction, and an interior volume between the elbow first end and the elbow second end. The filter element seal member is located on the elbow second end, wherein the filter element seal member is constructed to seal to a clean air intake, the filter element seal member located on the elbow second end defining a seal member cross sectional area. The filter element can be characterized as having a ratio of the seal member cross sectional area to the filter arrangement cross sectional area of at least 0.5. The filter element can have a z-filter media pack for a pleated media pack. The air filter element can be arranged in an air cleaner.

A system for cleaning environmental air, including a receptable for receive a filter, the filter when installed in the receptacle being instream with a heat radiator of a vehicle in an airstream when air is flowing, the heat radiator for cooling coolant fluid, the coolant fluid for transporting heat from a part of the vehicle to be cooled to the heat radiator. The system includes a controlling circuit for controlling a fan placeable in relation to the radiator so that at least part of the air flow is produced by the fan, when the fan is operating, and to determine if environmental air requires cleaning, and further to, when operate the fan when a vehicle speed is within a speed range of fan influence. The controlling circuit may be configured to not operate the fan when a vehicle speed is out of the speed range of fan influence.

An air cleaner includes: a generation unit configured to discharge an electric current by being applied with a high voltage, and generate a plurality of types of discharge products; an air-sending device configured to form a flow of air, and spray the plurality of types of discharge products generated from the generation unit to a space; an estimation unit configured to estimate an amount of dust floating in the space by selecting whether an amount of dust floating in the space is a first estimation amount smaller than a predetermined threshold or is a second estimation amount larger than or equal to the predetermined threshold and larger than the first estimation amount; and a control unit configured to control a generation amount of the plurality of types of discharge products to be generated from the generation unit based on the amount of dust estimated by the estimation unit.
