<p>The method involves temporarily subjecting a filter element (1) to high frequency pulsation impulses, which causes the filter element to oscillate. The filter element is blown up with upcoming purging air before the release of the pulsation impulses, so that positive pressure is developed in the filter element. The filter element is purged with the purging air during the pulsation impulses. The pulsation impulses are controlled depending on differential pressure. A cleaning head (7) is fixable at the filter element by a fixing device (6) i.e. catching gripper. An independent claim is also included for a cleaning device comprising a cleaning head.</p> |
