Abstract (en)
[origin: WO2019186232A1] A dirt-separating filtering apparatus (10) has a hollow body (11) provided with manually controlled valves (14) for controlling flow delivering of dirty fluid and draining the hollow body (11), a series of filtering elements (26) inside the hollow body (11), a series of brushes (35) for brushing the filtering elements (26), and a drive (24) for rotating the filtering elements (26) for brushing. The apparatus can be commanded, controlled and switched between a step of filtering and a step of cleaning the filtering elements (26). The apparatus is very simple, effective and low cost.
