What are the 3 adjustments on a paint gun?
Most spray guns have three basic controls that will allow you to adjust for optimum performance on your projects. These controls are: the fluid adjustment, the fan control, and the air micrometer (see diagram).
What is a siphon spray gun?
Product Overview. This general purpose siphon feed spray gun has a coated aluminum body combined with a removable fluid nozzle and air diffuser for quick and easy cleaning. Ideal for use with low viscosity paints, lacquers, enamels, stains and urethanes, this paint spray gun has ergonomic knobs for precise control.
What is the correct pressure for spray painting?
Setting the air pressure to about 28-29 PSI for clear will ensure you having great flow out. Most HVLP spray guns will use 10-14 scfm at 40 psi. This is volume of air pressure per cubic foot.
What is the difference between gravity feed and siphon feed?
A gravity fed paint gun generally means that the paint cup is on top of the gun. The paint naturally falls through the nozzle as you squeeze the trigger. A siphon or pump fed gun has the paint cup on the bottom of the gun and paint is pumped up through the nozzle as you pull the trigger.
What does HVLP stand for?
High Volume Low Pressure
HVLP is an acronym for High Volume Low Pressure which means a high volume of air at a low air pressure.
How does a siphon gun work?
A siphon feed spray gun works with compressed air. The cup on a siphon gun is located below the nozzle, and pressurized air creates a vacuum that sucks paint up to mix with it and create a fine spray. Paints that are sprayed with a siphon feed gun typically contain volatile solvents.
What does PSI at the cap mean?
HVLP air caps are typically rated for a maximum gun inlet pressure to achieve 10 psi at the air cap. For example if 50 psi inlet achieves 10 psi measured at the air cap, then an inlet pressure of 60 psi would exceed 10 psi at the air cap.

How do you adjust the air pressure in a spray gun?
You need to look for the setting that says at the gun. This means what pressure should be used going into the spray gun. Many painters, including myself, use a regulator at the end of the gun. This allows you to adjust the air pressure at the gun by adjusting the regulator.
How do you change the pattern of a spray gun spray?
If the pattern is heavy on one side or if the spray gun is spraying a half moon shape, turn the air cap 180 degrees and see if that changes the pattern. For example, if it was heavy on top, but it becomes heavy on bottom when the air cap is turned.
What kind of spray gun do you use to spray paint?
We have the old school one called the siphon feed spray gun. You put the paint in the cup and it siphons up and paint comes out. My dad used to spray with this and sometimes I use it, but not as much anymore. It’s good for heavy duty primers.
