The compressor (1) comprises: - a casing body (4) having an inlet (10) for a gaseous fluid to be taken in and at least an outlet (11) for the compressed fluid; - at least a male rotor (2) and at least a female rotor (3) meshed together, said rotors (2, 3) being arranged inside said casing body (4). The compressor (1) is characterized in that the ratio between the length (Lm) and the external diameter of the male rotor (2) is higher than or equal to two, and in that the winding angle (f) of the male rotor (2) is smaller than or equal to 300°.
