Filtration cartridges with metallic end members and method of manufacturing

摘要

The filtration cartridge comprises a filtration element and a heat-resistant extension band having a first and a second longitudinal edge. The first edge of the extension band is attached along an edge of the filtration element. The extension band is squeezed on a porous inner core and an end plate is welded on the end of the inner core. Providing filtration cartridges with a metallic end member allows increasing their resistance to mechanical shocks and increasing their maximum operating temperatures.
