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.

Filter element, in particular for gas filtration

A filter device is disclosed having a round filter element having a filter medium body with an open interior. The filter element is installable into a filter housing having a base filter housing and a housing cover, in which an inflow opening of the cover overlaps against and aligns with an inflow opening of a base housing part such they form a continuous inflow opening. A support mesh cage arranged on the radially outer wall of the annular filter medium body. The filter housing has a longitudinally extended cross-sectional shape in which the inflow opening and an outlet opening are both arranged on the base housing part at opposing sides of the base housing part.

Round filter element, in particular for gas filtration

A filter element has a filter medium body with a first side and an oppositely positioned second side. A first sealing or supporting element is arranged at the first side. A second sealing or supporting element is arranged at the second side. The first side is positioned in a plane. The second side has a first section and a second section, wherein the first section has a first spacing relative to the first side and the second section has a second spacing relative to the first side, wherein the first and second spacings are different. One of the first and second sides is the inflow side of the filter medium body and the other one of the first and second sides is the outflow side of the filter medium body.

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.

A filter element for filtering media with a pleated filter medium is described. Each pleat () is formed by two pleated sheets which form a pleat tip () with one another on the crude side () exposed to oncoming flow. Two neighboring pleats () form a pleat base () with one another, wherein the crude side () and/or the clean side () of the filter medium has a plurality of elongated adhesive sections along at least two adhesive traces (), each having at least one adhesive section and each having at least one adhesive interruption (). The mutual spacing of the two pleated sheets in the region of the pleat tip () is between zero and two mm or the two pleated sheets are in contact with one another in the region of the pleat tip (), wherein the pleat spacing () between the two pleated sheets of a pleat pocket () amounts to at least twice the pleat spacing in the region of the pleat tipin the region of the pleat base ().

Filter element for filtering media

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.

Air filter device, particularly for a motor vehicle

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.

A tank venting filter is provided with a housing extending in a direction of a longitudinal filter axis and provided with a bottom side and a topside opposite the bottom side. A filter element is arranged in the housing. The housing has an air inlet at the bottom side and an air outlet at the topside. The air inlet is provided in the housing transverse to the longitudinal filter axis. The housing has a housing bottom at the bottom side, wherein the housing bottom closes off a filter interior of the housing in a downward direction and is positioned at a spacing from the filter element. The housing bottom has an inner side facing the filter interior. The inner side ends in the air inlet and is positioned at least sectionwise at an obtuse angle relative to the longitudinal filter axis.

Tank venting filter

A filter element, in particular a flat filter element () for installation in a filter housing of a filter for a fluid, in particular an air filter, in particular for an internal combustion engine, in particular in a motor vehicle, and a filter are described. The filter element () comprises open filter bellows () made of a filter medium (), which has an oncoming flow side () and an outgoing flow side () for the fluid to be filtered. The filter element () has at least two hand grip elements () for gripping the filter element ().
