An air filter housing has an inner housing space adapted to receive an air filter element. The air filter housing includes a first housing end and a second housing end located axially opposite the first housing end in relation to the inner housing space, and an outlet pipe extending from the second housing end axially into the inner housing space. The outlet pipe has a center axis and an opening configured to receive clean air from the inner housing space, wherein at least an axial portion of the outlet pipe has a cross-sectional area along a geometrical plane perpendicular to the centre axis which is tapering.

Air filter housing and an air filter element

An air filter housing includes an inner housing space adapted to receive an air filter element. The air filter housing includes a first end and a second end located axially opposite the first end in relation to the inner housing space, and an outlet channel path extending from the inner housing space and out from the second end, the outlet channel path having a length X m, the length X m being adapted to stabilize a noise having a wavelength of Y m travelling through the outlet channel path towards the inner housing space, wherein the length X m is related to the wavelength Y m according to the following relationship: Y/16<X<Y/8.

Filter housing and an air filter system

A tube shaped air filter element for a fuel cell vehicle. The air filter element comprises a pair of circumferentially extending ridges on a first inner circumferential envelope surface, each of the pair of ridges protrudes towards a geometric centre axis of the air filter element and is configured to engage with an axially protruding portion of a filter housing.

Tubular air filter element

The invention relates to an air cleaner housing for a vehicle, comprising an outer and an inner circumferential wall, and a space therebetween adapted to house at least one filter element for filtering air, wherein the inner circumferential wall is provided with openings to allow filtered air to pass radially inwardly through the inner circumferential wall. The air cleaner housing comprises a first end and an open second end for fluidly connecting the air cleaner housing to a turbo, the open second end being located opposite the first end. The air cleaner housing comprises a resonator, wherein the entire resonator is encircled by the inner circumferential wall such that air entering through the inner circumferential wall passes on the outside of the resonator to and through the open second end.

Air cleaner housing for a vehicle

The invention relates to a filter element for mounting in an air cleaner housing of a vehicle. The filter element comprises a circumferential filtering wall through which air is allowed to enter. The filter element also comprises a first end and an open second end for fluidly connecting the filter element to a turbo. The open second end is located opposite the first end. The circumferential filtering wall extends from the first end towards the open second end. The filter element further comprises a resonator. The entire resonator is encircled by the circumferential filtering wall such that air entering through the circumferential filtering wall passes on the outside of the resonator to and through the open second end.

A disposable air filter unit for filtering air intake to an internal combustion engine forms a cylindrical sleeve about a central axis, and has an outer sleeve surface for receiving unfiltered air and an inner sleeve surface for output of filtered air. The disposable air filter unit includes a pleated filter component and a bioplastic reinforcement structure arranged at the pleated filter component. An air cleaner assembly includes a disposable air filter unit and a reusable carrier structure on which the air filter unit is removably arranged. The disposable air filter unit forms a sleeve about a central axis extending axially between a first end surface and a second end surface. The reusable carrier structure includes a receiving member for receiving the first end surface of the air filter unit and a sealing member arranged at the receiving member to contact the first end surface of the air filter unit.

Disposable air filter unit, an air cleaner assembly and an air cleaner arrangement

The present disclosure relates to an air filter housing arrangement () for a cylindrical air filter. In particular, the air filter housing arrangement comprises an at least partially cylindrical air filter housing () arranged to accommodate the cylindrical air filter, wherein the air filter housing comprises an axially and a radially open portion for allowing connection/removal of the cylindrical air filter in both an axial direction and a radial direction.

Air filter housing arrangement

The invention relates to an air filter housing for use in an air cleaning arrangement for cleaning air to be provided to an air inlet of an internal combustion engine. The air filter housing comprises: a filter housing inlet for receiving air; and a filter housing outlet for providing filtered air to the air inlet of the internal combustion engine when an air filter is arranged inside the air filter housing between the filter housing inlet and the filter housing outlet. The air filter housing further comprises a closing arrangement controllable to be in each of a first state in which the filter housing outlet is closed by the closing arrangement, and a second state in which the filter housing outlet is open. The closing arrangement may comprise an iris shutter.

Air filter housing with closing arrangement, air filter, and vehicle

The invention relates to a an air supply arrangement () for supplying air from the atmosphere towards an internal combustion engine in a vehicle, the air supply arrangement comprising an air intake () for intake of air from the atmosphere, an air outlet () for outlet of air towards the internal combustion engine, and an air duct () for leading air from the air intake () in a downstream direction to the air outlet (). A separator () is arranged in the air duct () so as to divide the air duct () into an upstream portion () and a downstream portion () for filtering of atmospheric air from debris by passage of said atmospheric air through the separator (). The air supply arrangement () further comprises a compressed air delivery arrangement () being arranged to supply compressed air towards the separator () for cleaning the separator () from assembled debris.
