Pneumatic painting apparatus of the present invention includes a compressor, a de-humidifier device, a heater for compressed air, a regenerating device for an adsorptive agent, a spray gun with a temperature sensor, a delivery pipe, and a control unit. The control unit opens upstream from the de-humidifier device. The circuit, along which the flow of air from the container of compressed air travels, includes passing through at least the heater and going along the delivery pipe of the compressed air flow towards a spray gun or vice-versa, not supplying the spray gun. The upstream circuit of the de-humidifier device closes, activating the regenerating device for the adsorptive agent of the de-humidifier device. The circuit takes a regenerating path inverse to the previous one, the circuit, from the compressed air container first crossing the heater device and later the de-humidifier device.
