Abstract: The invention relates to a system for producing and distributing compressed air that comprises at least one compressor (1) having connected thereto a suction pipe (2) for the intake of air and an output pipe (3) for air compressed by said at least one compressor, and distribution piping (4) connected to the output pipe (3) for distributing air to sites of use (5, 6). According to the invention, the system further comprises a return pipe (7) arranged between the suction pipe (2) and at least one site of use (5) for receiving air reduced in pressure in it and feeding it back to said at least one compressor (1).
