ABSTRACT:
A particulate filter cartridge has a woven metal fiber filter medium surrounding a perforated support tube. The filter medium is crimped down to the support tube at opposite ends thereof and then welded to the support tube at the crimped regions. A plurality of such cartridges can then be nested within each other and separated by appropriate exhaust gas flow directing baffles to form a particulate filter assembly.
