Abstract

A filter device including at least one filter element adapted to filter a raw fluid and having a raw fluid side and a clean fluid side, the filter element having a clean fluid outlet arranged on the clean fluid side and extending in a first plane, at least one clean fluid collecting channel into which the clean fluid outlet opens; at least one compressed-air cleaning-off device adapted to generate a pressure pulse for cleaning-off foreign matter adhering to the filter element and to conduct the same through the clean fluid outlet to the filter element, wherein the compressed-air cleaning-off device is adapted to conduct the pressure pulse at least approximately along the first plane to the clean fluid outlet, wherein the compressed-air cleaning-off device comprises a compressed-air supply channel operationally coupled to a clean fluid collecting channel outlet and adapted to charge the clean fluid collecting channel with pressure pulses.
