US 12,311,301 B2 · Filter element and method of manufacturing a filter element

Abstract

The present disclosure relates to a filter element comprising a filter medium pack and a support arrangement comprising at least a shell member, and wherein a portion of the shell member is thermally welded to a circumferential face of the filter medium pack. The present disclosure further relates to a method of manufacturing such a filter element, the method comprising heating at least a portion of the shell member of the support arrangement, positioning the shell member around the circumferential face of the filter medium pack, pushing the heated circumferential portion of the shell member against the circumferential face of the filter medium pack, and allowing the circumferential portion of the shell member to cool down.
