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.

Abstract: A hollow filter element for insertion into an openable filter housing has a filter medium body configured as a hollow body surrounding an inwardly positioned flow space. At least one end disk is connected to the filter medium body and covers an axial end face of the filter medium body. A positioning element is arranged at the at least one end disk and interacts with a housing-associated blade of the filter housing. The positioning element receives the housing-associated blade with form fit in two different transverse directions relative to the longitudinal axis of the filter medium body. The positioning element has a positioning recess.

Abstract: A filter element has a filter medium body enclosing an inwardly positioned flow space and having a center axis. A support frame is arranged at an inner side of the filter medium body. At least one circumferentially extending sealing ring lip is arranged at the filter medium body and projects axially in an axial direction relative to the center axis past an end face of the filter medium body. The sealing ring lip is designed to seal relative to a housing component of a receiving filter housing. A support ring is arranged at the end face of the filter medium body at a radial distance to the sealing ring lip in a radial direction relative to the center axis. The support ring is supported in the radial direction at the support frame and is formed as one piece together with the support frame.
