Abstract

A filter element has a support member with a support tube which can abut a filter mat and which is provided with apertures for the passage of a filtered medium. The apertures are formed by the axial spaces between individual rings of the support member. The rings are supported by support walls dividing the interior of the support tube into individual chambers. Since the support member is rendered compression-stiff, it exclusively supports the filter mat when the medium flows through. The respective support wall is directly connected to the rings. Each ring with its closed annular shape surrounds the support walls on the exterior. The filtration capacity of filter elements can be improved and the weight and cost simultaneously reduced owing to the highly stable and compression-stiff support member.
