Abstract:
An annular filter element has a filter medium body configured to be flowed through by a fluid to be purified in a radial direction. A sealing element is arranged at the end face of the filter medium body and extends circumferentially around the end face. The sealing element has at least one first sealing section comprising a massive and large cross-sectional area and one or more second sealing sections with a cross-sectional area that is at least partially reduced in comparison to the large cross-sectional area. The one or more second sealing sections include a second sealing section with a groove-type recess, wherein the groove-type recess extends at least approximately across a length of the second sealing section with the groove-type recess or across a portion of said length.
