What is the normal air pressure range at the inlet of a spraygun?

The normal air pressure range at the inlet of a spray gun typically falls between 30 to 50 psi. This range is optimal for achieving good atomization of the paint without creating excessive overspray or causing the paint to run or sag. At this pressure, the spray gun can deliver a fine mist of paint, ensuring even coverage and a professional finish.

A pressure that is too low could lead to poor atomization, resulting in larger droplets and an uneven application, while a pressure that is too high could create excessive overspray, wasting materials and potentially impacting the finish quality. Hence, maintaining the recommended pressure range is crucial for effective and efficient spray painting.
