How does a spray gun work?
A pneumatic spray gun uses the stream of air to create an area of low pressure that draws the paint into the flow, creating a mixture of atomized paint and flowing air, which drives the paint to the surface .
Why is airless spray better than air spray?
With airless spray due to the high pressure of the injection pump , the paint can be significantly more viscous than with an air spray gun. Flying out under high pressure, it calmly passes air particles, does not swirl, and falls on the surface to be painted. Due to this, the paint transfer coefficient for the airless method of painting is significantly higher than for the air method, and the productivity of painting works is several times higher than the productivity for air spraying.
What is the principle of spray guns?
The principle of operation of spray guns (both electric and pneumatic) is the creation of a kind of aerosol from a liquid material in the form of tiny droplets, which is directionally transferred to the desired surface.

Why do you use a nozzle on a paint gun?
The nozzle of the gun will be made so that the high pressure from the compressor is lowered at the outlet. Let the paint fly out at a lower speed, but the amount per unit of time will be greater. The airflow will be lower, which will allow you to keep the gun closer to the paint surface on which the paint falls.
What is the driving force of a pneumatic spray gun?
In pneumatic equipment, the driving force is a powerful stream of compressed air, which is pumped by the compressor and, getting into the spray gun, breaks the liquid to the minimum possible particles. To achieve the most uniform spray, it is necessary to select and set the material-air balance in the optimal ratio.
