1. A volumetric compressor comprising:
a body defining an operative chamber, a suction section, and a discharge section of an operating fluid;
at least two lobe rotors, wherein lobes of each of the lobe rotor are housed inside the operative chamber, each of the rotor configured to rotate around a corresponding longitudinal rotation axis;
a first header and a second header that delimit on opposite sides the operative chamber, wherein each of the first and second headers comprises:
a bank connected to the body and configured to support the at least two rotors;
a cover connected to the bank to define an inner volume comprised between the cover and the bank, and configured to house, in use, a lubricating bath; and a generator unit configured to generate a forced flow of cooling gas;
wherein, for each of the first and second headers, the respective bank defines a cooling chamber physically separated from the operative chamber and from the corresponding inner volume,
wherein each of the cooling chamber comprises an inlet communicating with the generator unit and an outlet for the cooling gas.
