Likewise, how does an HVLP spray gun work?
HVLP (high volume low pressure) means a high volume of material is displaced at a low pressure of air flow. This means that more of the paint propelled by the spray gun reaches the surface you are spraying with reduced wastage, overspray, and pollution of the air.
Also, what pressure to spray HVLP gun at? When spraying clear coat I usually like to up the pressure 2-3 psi for a little more atomization and better flow out. 28-29 PSI being the sweet spot in my opinion. Most HVLP spray guns will use up 10-14 scfm (air volume) at 40 psi. (Volume of air pressure per cubic foot).
Then, can you use a HVLP gun with an air compressor?
HVLP, which stands for “high volume low pressure,” are the most commonly used spray guns today. They are highly efficient and offer a controlled spray with little overspray. Some HVLP guns are powerful enough that they can be used without an air compressor, while others require a large air compressor to operate.
Why is my HVLP spray gun spitting?
Spray guns spit when air is being introduced into the fluid outside of at the air cap. A loose fluid nozzle does not properly seat in the tip of the spray gun and causes air to enter the fluid supply resulting in spitting.
