A passive particulate filter assembly for filtering diesel exhaust. The assembly includes a housing unit defining a filtering chamber having an inlet port and an outlet port. A cylindrical inner core member is disposed in the filtering chamber and is surrounded by a pleated cylindrical filter pack having first and second opposite ends. An end cap couples with the first end of the filter pack and is configured to prevent exhaust flow there through. An end plate is coupled to the second end of the filter pack and is configured to secure the filter pack to the housing unit. The filter pack comprises a woven metal fiber medium preferably manufactured from stainless steel or a nickel-chromium-iron alloy having a porosity of between about 2 to about 15 žm. |
