An air compressor utilizing an electronic control system. A pneumatically controlled regulator is provided for controlling output pressure for an air compressor. Digital gauges are provided on the air compressor to replace conventional mechanical gauges. A variable speed motor is used, which in turn varies the speed of the pump. Tools are provided for an air compressor that are capable of transmitting a signal to the air compressor indicating a desired pressure and/or motor speed at which the air compressor is to operate.
