A device for filtering a fluids stream comprising a hollow body (1) having an inlet (2) and an outlet (3) for the fluids stream, a screen mesh (4) disposed in the hollow body which substantially traverses the flow path of the fluids stream to define an upstream portion and a downstream portion of the hollow body, and sediment separating means attached via tubes (5 and 6) to remove sediment gravitating towards a lower area of the upstream portion of the hollow body. The sediment separating means includes (a) an inlet attached to tube (5) located in the lower area of the upstream portion to remove a partial stream of the fluids stream in which sediment is entrained, (b) a sump (7) to receive the partial stream and substantially separate the sediment from the partial stream, and (c) an outlet (9) to return the partial stream from the sump (7) means into tube (6) and into the downstream portion of the hollow body (1). |
