A centrifugal separator and a method (1) for separation of particles from a gas stream is disclosed. The separator comprises a frame (2), a gas inlet (3) and a gas outlet (4). A centrifugal rotor (5) is arranged to be rotatable in the frame around a rotational axis (x) and comprising a separating member (6). A central gas chamber (8) in the rotor communicates with a radially inner portion of the separating member and the gas outlet. A space (9) surrounding the rotor communicates with a radially outer portion of the separating member and the gas inlet. Drive means provides rotation of the centrifugal rotor (5) for separating particles from the gas stream being conducted from the space surrounding the rotor, through the separation member and towards the central gas chamber. A ring-formed sealing arranged between and in sealingly contact with the first frame portion (15a) and the centrifugal rotor. This improves the separation performance of a centrifugal separator for separation of particles from a gas stream, by reducing pressure losses and leakage from the central gas chamber.. |
