Abstract

A filter element has a filter body having a longitudinal axis and a concentric shape relative to the longitudinal axis. The filter body has a first end face and a second opposite end face. A first end disk is arranged at the first end face. A second end disk is arranged at the second end face. A support tube concentric to the longitudinal axis extends between the first and second end disks. At least one of the first and second end disks has support knobs arranged in a circular arrangement about the longitudinal axis and extending in axial direction outwardly. The support knobs, when the filter element is mounted in a housing that receives the filter element, rest against an inner cover contour of the housing and fold over in radial direction outwardly so as to be supported axially and radially on the housing.
