Abstract:
A support tube for a filter element, in which the support tube is an elongated tubular member having a central longitudinal axis extending through a hollow interior of the support tube. The support tube has a plurality of through openings extending through a circumferential wall of the support tube and is formed in one piece and a unitary component. The plurality of through openings are bounded by at least five longitudinal webs which are polygonal in cross section in at least some sections in the longitudinal direction of the support tube. The at least five longitudinal webs are in each case formed symmetrically.
Abstract:
A filter element of an air filter, including: a filter medium for filtering air, partially surrounding an element interior of the filter element with respect to an element axis; wherein the filter element replaceably arranged within an openable filter housing having at least one inlet for air to be purified and at least one outlet for purified air so that said filter element separates said inlet from said outlet; wherein the filter element has at least one element-side support element on an outer side facing away from the element interior on at least one end face which is axial with respect to the element axis; wherein the support element includes at least one element supporting portion, which, at least in the installed state of the filter element in the filter housing, has a surface contour deviating from a flat surface on its end face facing away from the element interior.
Abstract:
An air filter device for a motor vehicle, having a filter element received in a filter housing which, at least in sections, is surrounded by an encompassing frame part. A support bead is held on the filter housing which protrudes over the directly adjacent filter housing wall, wherein a sealing element on the frame is supported by the support bead on the housing.
Abstract:
Disclosed are an air filter element, a filter housing, and an air filter in which the air filter elements have a high filtering capacity and a long service life by increasing the filter surface of an air filter element taking into account structural requirements for the air filter housing.
Abstract:
A filter element has a filter medium body with a first side and an oppositely positioned second side, wherein one of the first and second sides is the inflow side of the filter medium body and the other one is the outflow side of the filter medium body. A first sealing or supporting element is arranged at the first side. A second sealing or supporting element is arranged at the second side. At least one force-transmitting adhesive bead extends between the first side and the second side, wherein the at least one adhesive bead is a force transmitting element extending between the first and second sealing or supporting elements.
Abstract:
A filter element for filtering media with a pleated filter medium is described. Each pleat (6) is formed by two pleated sheets which form a pleat tip (7) with one another on the crude side (3) exposed to oncoming flow. Two neighboring pleats (6) form a pleat base (8) with one another, wherein the crude side (3) and/or the clean side (4) of the filter medium has a plurality of elongated adhesive sections along at least two adhesive traces (14), each having at least one adhesive section and each having at least one adhesive interruption (15). The mutual spacing of the two pleated sheets in the region of the pleat tip (7) is between zero and two mm or the two pleated sheets are in contact with one another in the region of the pleat tip (7), wherein the pleat spacing (9) between the two pleated sheets of a pleat pocket (11) amounts to at least twice the pleat spacing in the region of the pleat tip 7 in the region of the pleat base (8).
Abstract:
Disclosed are an air filter element, a filter housing, and an air filter in which the air filter elements have a high filtering capacity and a long service life by increasing the filter surface of an air filter element taking into account structural requirements for the air filter housing.
Abstract:
A filter element, including: a plurality of superposed single sheets, each sheet including a corrugated layer; and a covering layer for forming parallel flow channels; wherein the plurality of superposed single sheets are connected to one another; wherein the plurality of single sheets are not flat and have at least one curvature and are connected in the curved state, so that the curved filter element formed from the single sheets is inherently stable and have an axis of curvature that extends parallel to the flow channels.
