Abstract (en)

Pre-filter device for air and dust for a cleaning apparatus, able to be positioned at the entrance to a filter unit (12) of a suction device for air and dust. The pre-filter device comprises a shaped hollow body having a first portion (11) for the entrance of a stream of air and dust, a second treatment portion (13), disposed downstream of the first portion (11) and a third portion (15) disposed downstream of the second portion (13), through which the stream of air and dust exits. The second portion (13) is provided with introduction means (17) to introduce a jet (20) of gas or steam suitable to hit the stream of air and dust. The second portion (13), at least in correspondence with the introduction means (17, 19), has a passage section bigger than the passage section of the first portion (11), so as to determine, during normal use, a slowing down of the speed of the stream of air and dust and so as to increase the contact time between the jet (20) and the stream of air and dust.
