AN APPARATUS COMPRISING A FILTERING DEVICE AND RELATIVE CLEANING SYSTEM

An apparatus comprises a filtering device (2) which includes a plurality of filtering elements (3) made of a filter material. The apparatus further comprises a cleaning system (1) for periodically cleaning the filtering device (2) in order to remove contaminating particles from the filtering device (2). The cleaning system (1) has at least one percussion element (6) for applying percussions at least on an impact surface (10) of an intermediate structure (100), so as to generate, for each percussion, an impact which is able to detach from the filter material a first fraction of the contaminating particles adhering to the filter material and then vibrate the filter material to detach from it further contaminants. The intermediate structure (100), which is interposed between the percussion element (6) and the filter material, has an inner region (50) delimited at least partly by the impact surface (10) and an outer region (60) which surrounds at least partly the inner region (50). The intermediate structure (100) has a capacity to absorb the energy deriving from the percussion which is greater in the inner region (50) than the outer region (60).
