An air/oil separator ( 40 ) comprises a rotor ( 60 ) and a casing ( 62 ) surrounding the rotor ( 60 ). The casing ( 60 ) has an inlet ( 64 ) at a first axial position (A) for the supply of an air and oil mixture into the air/oil separator ( 40 ). The rotor ( 60 ) has an outlet ( 66 ) for discharging cleaned air from the air/oil separator ( 40 ). The rotor ( 60 ) carries a plurality of porous members ( 68, 70, 72 ). The porous members ( 68, 70, 72 ) have an inlet ( 74 ) at a second axial position (B) and an outlet ( 76 ) at a third axial position (C). The third axial position (C) is arranged axially between the first axial position (A) and the second axial position (B). A first passage ( 88 ) supplies the air and oil mixture from the inlet ( 64 ) in the casing ( 62 ) to the inlet ( 74 ) to the porous members ( 68, 70, 72 ). A second passage ( 94 ) supplies cleaned air from the porous members ( 68, 70, 72 ) to the outlet ( 66 ) in the rotor ( 60 ). In use the air and oil mixture flows through the porous members ( 68, 70, 72 ) in the opposite direction to the air and oil mixture flowing through the first passage ( 88 ).
