Abstract

An annular filter element has a filter medium body that can be flowed through in a radial direction by a fluid to be cleaned. A central tube is arranged at an inner side of the filter medium body. A support collar is connected to the central tube and provides an end face forming an axial support surface for a housing component of a filter housing. A sealing element is connected to the support collar. The support collar has a radial side face, wherein the radial side face carries the sealing element and forms a sealing surface for the housing component, wherein the sealing surface is spaced apart from the axial support surface. The support collar is formed together with the central tube as one piece.
