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.
