Do You Know How many Types of Spray Gun?

1. Siphon spray gun:

The paint of the siphon feed spray gun is located behind the nozzle of the spray gun. When spraying, the airflow is used to attract the paint to the upper side, and the paint mist is caused by the pressure at the nozzle. It is relatively stable and convenient for adding paint or changing colors. But it is difficult to spray horizontal surfaces. Because the changes in viscosity will cause changes in displacement and the paint cans are heavy, so operators are prone to fatigue.

2. Gravity feed spray gun:

The paint cup of the gravity feed paint spray gun is on the spray gun nozzle, and the paint is sprayed on the surface of the object by the weight of the paint and the pressure difference generated by the airflow at the tip of the nozzle. The operation method is the same as the siphon type, which is convenient for adjusting the position of the paint cup when using. But due to the paint cup is installed above the nozzle, it will affect the stability of the spray gun.

3. Pressure feed spray gun:

The nozzle of the compression spray gun is flush with the bottom of the air cap, and the paint is pressed against the air cap without forming a vacuum place. The pressure is provided by an independent pressure tank. There is no need to stop and add paint to the paint can when spraying large surfaces. But it is not suitable for small area spraying, because it takes more time to change the color and clean the spray gun.
