The compressor has a fresh air suction pipeline (12) opening on a compression stage with a compressor impeller (18) housed in a casing (16). A butterfly valve (13) is movable around an axis between a full open position and full close position. An annular chamber (26) is disposed coaxially to the impeller and around the pipeline and permits to spin the fresh air before its introduction within the suction pipeline.
