Abstract

In a filter (1, 101) for removing soot particles, especially from diesel engine exhaust, high efficiency can be achieved by a tube (5, 105) which is surrounded by filter material (7, 107) and through which the exhaust flows and which has a perforated sleeve surface in a housing (4, 9). <IMAGE>
