An air-powered siphon spray gun operates by using compressed air to create a vacuum that draws liquid from a container and atomizes it into a fine spray. The main components of a siphon spray gun include a nozzle, an air cap, a fluid tip, a siphon tube, and a container or cup for the liquid. When the trigger of the spray gun is pulled, compressed air flows through the gun and exits through the air cap. This high-speed air stream creates a low-pressure area at the nozzle. The pressure difference between the atmosphere and the low-pressure area causes the liquid in the container to be drawn up through the siphon tube. As the liquid reaches the nozzle, it encounters the high-velocity air stream. The interaction between the liquid and the air stream breaks the liquid into tiny droplets, creating a fine mist or spray. The size of the droplets can be adjusted by changing the air pressure, the size of the fluid tip, or the distance between the nozzle and the surface being sprayed. The siphon spray gun is versatile and can be used for various applications, including painting, coating, and applying finishes. It is particularly useful for spraying thicker materials, as the siphon action can handle higher viscosity liquids compared to gravity-fed spray guns. Overall, the air-powered siphon spray gun is a simple yet effective tool for achieving a uniform and controlled application of liquids over surfaces.
