A FILTER CLEANING APPARATUS AND AN ASSOCIATED CLEANING METHOD

摘要

Apparatus (32) for cleaning a filter (10) includes a stationary hollow member having at least one aperture (37) for the intake of a cleaning fluid and a plurality of holes (40) for the exit of this cleaning fluid. The apparatus (32) can be fitted to the outside of the filter (10) in such a way that the cleaning fluid exiting from the said holes (40) is directed at the outer surface of the filter (10). It is preferable if the hollow body includes a coil/shaped length of tube (34).
