ABSTRACT:
A filter apparatus deposits impurities from a fluid stream by use of a filter element (10) accommodated in a filter casing (12). The filter casing (12) has a swirl space (14) such that the fluid stream to be filtered is conducted at least partly in a swirling flow around the filter element (10). The properties of a cyclone are utilized for the actual filtration operation to the extent that the swirl space of the filter casing brings about multiple deflection of the direction of motion of the fluid to be filtered.
