A centrifugal separator for cleaning gas

A centrifugal separator for cleaning gas containing contaminants, said centrifugal separator comprising:

• a stationary casing, enclosing a separation space through which a gas flow is permitted;
• a gas inlet extending through the stationary casing and permitting supply of the gas to be cleaned;
• a rotating member comprising a plurality of separation members arranged in said separation space and being arranged to rotate around an axis of rotation;
• a gas outlet tube arranged through the stationary casing and configured to permit discharge of cleaned gas out from the stationary-casing casing;
• a drainage outlet arranged in the stationary casing and configured to permit discharge of liquid contaminants that have been separated from the gas out from the stationary casing;
• a drive member for rotating the rotating member;
• and
• a stationary insert arranged in the stationary casing and configured for segregating cleaned gas and separated contaminants prior to the cleaned gas and separated contaminants exiting said stationary casing,
• wherein said gas outlet tube and said stationary insert are formed as a single unit.
