Abstract
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. In a first embodiment, a metallic cast end member is formed by immersing the second edge of the extension band into molten metal. The molten metal is then allowed to solidify with the second edge of the extension band embedded therein. In a second embodiment, 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.
