Abstract
A filter device has a filter housing (2, 4) accommodating a filter element (16) separating an unfiltered substance chamber (26) from a filtrate chamber (20) within the filter housing (2, 4). The filter element (16) is sealed against the filter housing (2, 4) by a sealing device (36, 40). The filter element (16) is mounted inside the filter housing (2, 4) using movable bearings (32, 38).
