Abstract:
A filter element, in particular a flat filter element (10) 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 (10) comprises open filter bellows (16) made of a filter medium (18), which has an oncoming flow side (28) and an outgoing flow side (30) for the fluid to be filtered. The filter element (10) has at least two hand grip elements (46) for gripping the filter element (10).
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 has a filter bellows and at least one support element arranged on the filter bellows that supports the filter element relative to a filter housing in which the filter element is to be arranged. The at least one support element is arranged on at least one edge of the filter bellows and projects outwardly past the filter bellows. The at least one support element is detachably or non-detachably attached on the filter bellows directly or indirectly. The at least one support element is preferably arranged on a corner of the filter bellows and projects past all sides of the filter bellows adjoining the corner. An air filter with a filter housing is furnished with the filter element.
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:
Disclosed is an air filter element (200) for insertion into an air filter housing, comprising an intake surface (275), a discharge surface (285), a filter medium (210), and a filter element-retaining device (240) which extends along at least a section of the periphery of the filter medium (210), between the intake surface (275) and the discharge surface (285), and which includes a retaining arrangement (270) that radially projects from the filter medium (210).
Abstract:
A round filter element has a filter medium body flowed through by a fluid to be purified in radial direction relative to a longitudinal axis of the filter medium body. The filter medium body radially encloses an inwardly positioned flow space. An end disk is arranged at an end face of the filter medium body. The end disk has a shaped body axially delimiting the inwardly positioned flow space. The end disk has a sealing disk arranged externally at the shaped body, wherein the sealing disk covers the shaped body and the end face of the filter medium body. The shaped body has a receiving depression that is flow-tight relative to the inwardly positioned flow space. The sealing disk has a receiving opening aligned with the receiving depression of the shaped body. The receiving depression and the receiving opening can receive a support element of a filter housing.
Abstract:
A filter element has a filter bellows of filter medium laid into folds. The folds extend between oppositely positioned end edges of the filter bellows, respectively. The end edges form oppositely positioned end edge surfaces. The filter bellows is arranged in closed configuration about a longitudinal axis and encloses a hollow space. The filter bellows has opposed end faces sealed by an end disc. The filter bellows has a cut portion in at least one of the oppositely positioned end edge surfaces such that one or more regions of folds with shortened fold length are formed. A fold length of the folds with shortened fold length is substantially identical at an outer and inner circumference of the filter bellows. A filter system has a housing in which the filter element is arranged. One of the housing parts has a region corresponding to the cut portion of the filter bellows.
Abstract:
A cover for a filter system for filtering a fluid has a fluid channel arranged at an inner side of the cover. The cover has a rim and at least one opening arranged in the rim to allow the fluid to pass through, wherein the opening is connected in fluid communication with the fluid channel. The fluid channel is connected in fluid communication with the interior of a filter element of the filter system. A seal for the cover has a first sealing ring and a second sealing connected to each other by flanks. The filter system has a housing with a housing part that is closable by the cover. A filter element is exchangeably arranged in the housing, and the fluid channel of the cover is connected in fluid communication to the interior of the filter element.
Abstract:
A secondary element with a first open end and a second end positioned opposite the first end has a filter medium arranged about a longitudinal axis of the secondary element and extending from the first open end to the second end. A closed end disc is disposed at the second end and seal-tightly closes off the second end. The closed end disc has a first connecting element that, for an intended installation of the secondary element in a filter system, is configured to interact with a second connecting element of a support tube of the filter system to secure the secondary element on the support tube. A filter system with such a secondary element has a support tube provided with a complementary second connecting element, wherein the secondary element is secured on the support tube by the first and second connecting elements engaging each other.
