How much pressure does a HVLP gun need?
HVLP, or High-Volume/Low Pressure, uses a high volume of air (typically between 15-26 CFM) delivered at low pressure (10 PSI or less at the air cap) to atomize paint into a soft, low-velocity pattern of particles. In most cases, less than 10 psi is needed in order to atomize.
How many CFM do I need to run a HVLP spray gun?
– An HVLP Spray Gun uses a lot of air and the more you have the better. However, you will typically always need at least 8 CFM for the lowest consuming air volume HVLP Spray Gun, we recommend a minimum of 30 CFM to prevent issues with the gun not atomizing well and changes in the fan pattern occurring.
How many PSI does it take to paint a car?
Look for a minimum of 15 psi, with some applications, such as clear coat, better-suited to 20 or 25 psi. Horsepower: For auto painting, a 10hp compressor will typically suffice. However, higher horsepower compressors may operate more efficiently, and can be used for other tasks.
How does a pressure pot sprayer work?
Pressure pots use compressed air to feed a pressure pot which will force feed coating to a spray gun. You can use a pressure pot with an HVLP, conventional, or LVMP spray gun. Compared to an airless paint sprayer, a pressure pot will not supply as high volume of fluid at a given time.
How does a pressure feed spray gun work?
Pressure and Siphon-feed guns are the oldest of designs. In pressure guns the fluid is pressurized, allowing it to flow out (these aren’t used much anymore). In siphon guns the movement of the air inside creates a siphon that pulls paint out of the reservoir. The Air Cap is the part that does the real work.
Can you paint a car with a 15 gallon compressor?
You can take a chance and paint the entire car at one shot if you can hear and feel the air pressure drop and adjust accordingly. When painting with a smaller tank like a 15-25 gallon …you’ll have to keep draining the tank every 2-3 passes around the car just to be safe.
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.
Which spray gun is best gravity or suction?
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.
How much pressure do you put on a pressure pot?
Connect your the air lineairline to your pressure pot ensuring you are using filtered air so that you do not contaminate the product. Close your relief valve and slowly turn the air regulator up (clockwise). TIP – Normally you will only require between 2 and 5 PSI of pot pressure when spraying two-pack and enamel.
What should the pressure be on a HVLP spray gun?
Most HVLP spray guns will use up 10-14 scfm (air volume) at 40 psi. (Volume of air pressure per cubic foot). 10-15 psi when trigger is pulled for base coat is what most say to set your gun at. Personally I spray at about 17 psi when spraying base coat and 20-25 for clear coat using the low volume low low pressure spray guns.
What should the pressure be on an airless sprayer?
Additionally you should gradually increase your airless sprayer pressure settings until any tails in your spray pattern disappear but not increase much above that so that you minimize overspray and paint waste.

How do you hook up a pressure pot to a spray gun?
Connect one end of the fluid line to the fluid outlet on the pressure pot (3/8 bsp) and the other to the fluid inlet of the spray gun. The air lineairline needs to be connected to the air regulator on the pressure pot with the opposing end connected to the air inlet on the gun.
