<p>The invention refers to a centrifugal separator for cleaning of a gas containing liquid impurities. A stationary casing (1) encloses a separation space (2) and has an inner wall surface (3) facing the separation space. An inlet (9) is provided for the gas to be cleaned. A rotating member (4) is provided in the separation space downstream the inlet and arranged to rotate in a direction (r) of rotation around an axis (x) of rotation. The rotating member brings the gas to rota- tion in the direction (r) of rotation for separation, by means of centrifugal forces, of liquid impurities from the gas. A gas outlet (10) is provided downstream the rotating member for discharge of the cleaned gas. A first liquid outlet (11) is provided upstream the gas outlet and downstream the rotating member for discharge of sepa- rated liquid impurities and comprises at least one outlet hole. A surrounding ring groove (19) extends outwardly from the inner wall surface in the stationary casing and has a surrounding bottom surface (20), wherein the outlet hole extends outwardly from the bottom surface.</p>
