A device for the pneumatic operation of a tool includes a generally closed pressure fluid circuit ( 2 ), at least one compressor ( 5 ), for increasing the pressure of the pressure fluid in the circuit, the compressor ( 5 ) having an inlet and an outlet, and a tool driven by the pressure fluid in the circuit, and through which the pressure fluid is transported in the circuit from the outlet to the inlet of the compressor ( 5 ). The pressure that is generated by the compressor and the load adopted by the tool ( 8 ) are adapted such that the pressure of the returning pressure fluid downstream the tool ( 8 ) is higher than the pressure of the surrounding atmosphere.
