Abstract
A filter device has a filter housing () having a fluid inlet () for unfiltered matter, a fluid outlet () for filtered matter and at least one filter element () of one or more parts accommodated in the filter housing (). The filter element can be cleaned using at least one backwash element () in counter current to the direction of filtration. The backwash element can be moved by a fluid-conveying drive shaft () of a rotary drive at the inside () of the relevant filter element (). At the end adjacent to this inside (), a gap-shaped passage opening is parallel to the axis of rotation () of the drive shaft () and opens into a flow chamber connected to the drive shaft () in a fluid-conveying manner. The distance between the backwash element () and the adjacent assignable filter element () can be predetermined by an adjustment device ().
