FILTER ELEMENT AND FILTER SYSTEM

A filter element has a filter medium arranged between first and second end disks. The first end disk has a positioning and sealing section having external positioning recesses for engaging disturbance geometries of a filter housing with form fit to position the filter element circumferentially in the filter housing. The positioning and sealing section has an inner interface for radially sealing and axially positioning the filter element relative to the filter housing. The interface, viewed along a longitudinal direction from first toward second end disk, extends farther into the positioning and sealing section than the positioning recesses. The interface has an annular seal groove surrounding a symmetry axis of the filter element and configured to engage a seal rib of the filter housing with form fit for axial positioning relative to the filter housing. A filter system is provided with such a filter element in its filter housing.
