During the spray painting of the automobile, the cleaning and drying of the metal surface of the automobile should be considered. The oil and dust on the surface will cause unflattens of the paint and then fast corrosion.

The oil-free compressed air can effectively eliminate these problems. The paint, along with compressed air, will be blown onto the clean surface of the metal through spray gun and mechanical arm. The oil-free air can protect the adhesive ability of paint, ensuring that there will be no pealing off of paint at the surface of the automobile in a long period of time.
