Abstract

A filtering apparatus 1 for liquid comprises a chamber 3, inlet 4 for liquid with debris therein, a first outlet 5, a second outlet 6 and filter 7 for filtering liquid. The inlet and second outlet have a flow path P therebetween, and liquid filtered by the filter leaves the chamber via the first outlet. The second outlet is arranged to receive debris and liquid that has not left the chamber via the first outlet. In one aspect, the flow path at the inlet is laterally offset from a notional central axis of the chamber so that liquid is supplied tangentially to a wall of the chamber. In another aspect, the flow path immediately before the filter is oblique to a tangent to a point on the surface of the filter where the flow path meets the filter. Preferably, the filter comprises a plastics mesh. The chamber may comprise a third outlet (8, Fig. 3) as an overflow.
