ABSTRACT:
A filter for the separation of impurities from waste gases, in particular from the exhaust gases of an internal combustion engine, possesses a filter body, which consists of a plurality of compression moulded and high temperature resistant filter plates (10), in particular made of sintered metal powder, metal filings, metal fibres or a mixture thereof, which are disposed above or next to one another and between them form a plurality of flow ducts. To form inlet ducts (3) and outlet ducts (4) the flow ducts are open at one side and are closed on the other side. Walls of the filter plates (1) lying between the inlet and outlet ducts (3, 4) represent filter surfaces. Heat conducting sheets (5) are inserted into the inlet ducts (3).
