The invention refers to a compressed air system (100) for a motor vehicle with an air supply system (200), comprising: - an electric drive motor (8), which can be controlled for variable speed, - an air compressor (9) coupled to be driven by the electric drive motor (8), - an electric power supply (6) for supplying electric power to the electric drive motor (8), - at least one air reservoir (11) connected with said air compressor (9) to receive air from the air compressor (9), - an air utilization system (300) connected to said at least one air reservoir (11) to receive air from said at least one air reservoir (11), - a controller (7) to control the speed of the electric drive motor (8). According to the invention, that the controller (7) controls the electric drive motor (8) to determine the speed of the electric drive motor (8) depending upon at least one signal out of the following signals: - A signal representing the activation status of an accelerator pedal (21) of the vehicle, - a signal representing the speed of the vehicle, - a signal representing the temperature of the power supply (6), - a signal representing the temperature of the electric drive motor (8), - a signal representing the wetness level of the air compressed by the air compressor (9), - a signal representing the load of the air compressor (9), - a signal representing the running time of the air compressor (9), - a signal representing the status of the electric power supply (6).
