Abstract

A self cleaning filter unit for irrigation systems, the unit comprising a housing having a water inlet (2), a water outlet (4) and a cleaning exhaust passage (13). The filter unit has a cylindrical filter (6) with the water inlet directing water to the interior of the filler element. A rotatable hollow member (17) carrying a brush (21) has an inlet opening (19) adjacent said filter is connected to a turbine (16) to pass water to said exhaust passage, so that with the exhaust passage open the flow of water through the inlet opening (19) of the hollow member (17) sweeps debris through the turbine (16) to the exhaust passage (13), the turbine (16) rotating the hollow member (17).
