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.

Round filter element, in particular for gas filtration

An air filter, including: an openable filter housing having an inlet for air to be cleaned, an outlet for cleaned air, a filter element exchangeably arranged with the filter housing. The filter element includes a filter medium radially surrounding and defining an interior space within the filter element and a support element secured to the filter element. The support element faces away from the filter medium and has a lateral support surface having a cylindrical section and/or a section with a cross section that changes in the direction of the element axis, whose main axis runs axially or parallel to the element axis and with which the support element is supported at least transversely to the element axis against a corresponding support section arranged on a side of the filter housing.

Air filter, filter element and filter housing of an air filter

An air filter () includes an openable filter housing () and a filter element (). The filter housing () includes an inlet () and an outlet. A filter element () with a filter medium () is disposed replaceably in the filter housing separating the inlet () from the outlet (). The filter element () features on an exterior side facing away from the element interior space () on an axial front face relative to the element axis () at least one supporting element () having at least one supporting lateral surface () with at least one cylindrical portion and/or at least one portion with a variable cross-section in the direction of a main axis. The supporting element () is supported at least transversely in relation to the element axis () with the at least one supporting lateral surface () against at least one corresponding support portion () on the side of the filter housing ().
