What pressure should I set my HVLP spray gun at?
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.
How big of an air compressor do I need for a HVLP spray gun?
HVLP guns require plenty of air, so you need to have a larger capacity compressor higher than those used for diy home works. In order to spray the full range of finishing products, however, you need at least a 21⁄2 to 3 HP compressor with a 75 liters (20 gallons) tank.

What's the difference between HVLP and RP spray guns?
HVLP is a general industry terms and stands for ‘High Volume Low Pressure’ (at least 65% transfer efficiency). ‘RP’ is a SATA acronym for ‘Reduced Pressure’. … Compliant” means that the guns comply with the legislation of the EU VOC directive and also deliver at least 65% transfer efficiency as the HVLP do.
How can you tell the difference between HVLP and conventional spray guns?
The high pressures of conventional spray guns turn paint into a finely atomized mist, giving you a thinner, finer application. HVLP spray guns produce a thicker coat due to their lower pressure, producing large droplets.
What paint to use on HVLP?
HVLP paint sprayers work with oil-based paint, but thicker paints such as water-based latex can clog the sprayer. Combine a half cup of water for every gallon of latex paint in a bucket and stir thoroughly to thin its consistency before using latex paint an HVLP gun.

That means you should choose an air compressor that has the capability of delivering up to 7.5 CFM at 40 PSI. As I said, 40 psi is the average pressure rating of an HVLP spray gun.
How much thinner do I add to oil based paint?

Summary. In most cases, a gravity feed paint spray gun is the better choice thanks to its efficient and versatile design. Although HVLP is a requirement in most areas, whether or not you use an HVLP gun, gravity feed offers the advantage over conventional feed because of the lower air pressure requirement.
