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.

What pressure should I set my spray gun?
The working range is between 15 and 50 psi, with smaller patterns requiring lower pressure. No two sprayers are likely to agree on the same settings, so it’s a matter of personal feel. Some typical settings: 15 to 20 psi:Airbrushing, touch-up, shading, sunbursting, and thin finish materials.
How much pressure does a paint sprayer need?
What is the best air pressure for spray painting? Again, it’s essential you check your specific model’s recommendations, but your HVLP spray gun PSI will likely sit between 25-30 PSI for something like using an air compressor for spraying cars, rising to 40 PSI in some cases where higher atomisation is needed.
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 is better HVLP or LVLP?
HVLP guns use more CFM and will require users to size their air compressor accordingly. On the other hand, LVLP atomizes better, sprays faster and lays down a better finish while using less CFM but high air pressure.
What psi do you spray clear coat?
When spraying base coat clear coat systems, you want to spray at 26-29 PSI. You measure this PSI by pulling the trigger and letting air flow through the tip of your gun with your dial or digital readout saying 26-29 PSI.
How many CFM do you need to paint a car?
Painting a Car – What Size Air Compressor To Paint Your Car? It’s recommended to pick yourself up a 60 Gal tank with a 5-6 HP compressor that put’s out enough CFM that will supply your spray gun. Look for CFM in the ranges of 14-18 at 90PSI.
Do HVLP paint sprayers need an air compressor?
HVLP turbine units use electrical power to generate air that is used with a HLVP turbine spray gun. Turbine spray units will deliver finishes that are similar in quality to a standard paint spray gun, but without the need for a compressor.
Why does my HVLP spray gun spitting?
“Spitting” happens when your paint gun’s nozzle is not properly screwed into place. If your paint gun is spitting or dripping paint, it is probably because the nozzle is not screwed on tightly. If you’ve checked your nozzle and find that it is screwed on tightly, you may need to purchase a new nozzle altogether.
Why is my paint sprayer leaving lines?
The main causes of streaks and disturbances in the spray pattern when using Airless devices are: Pressure set too low. Nozzle worn. Material supply disrupted (eg clogged filters)
Can you paint a car with a HVLP sprayer?
The HVLP spray gun has become a favorite of many users. It is ideal for painting smaller areas like a body panel, bumper, fender, or other kinds of small detail. This automotive paint gun also provides a nice, even finish.
What psi do you spray primer?
To begin, set it at 50 psi. Close the air volume control knob (usually located beside where the air hose enters the gun) and with the trigger pulled, open it to the point where the air volume starts to stay the same, and then stop.
What is the best pressure for car painting?
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.
What causes orange peel in paint?
Orange peel is typically the result of improper painting technique. It is caused by the quick evaporation of thinner, incorrect spray gun setup (e.g., low air pressure or incorrect nozzle), spraying the paint at an angle other than perpendicular or applying excessive paint.
Can you paint a car with a LVLP gun?
Yes, absolutely. You can shoot both base coat, clear coat as well as metallics. I’d recommend the LVLP if you’re on a tight air compressor set up. If you want to be technical, HVLP spray guns are for good for base coat while an LVLP spray gun is recommended for clear coat.
How much CFM do I need for LVLP?
It requires very little air for operation, which means it can be used with a small air compressor. This spray gun has a specific air consumption of about 3.5CFM to 3.9 CFM at 30 psi. For the best optimal outcomes, opt for a working pressure that is between 25 to 45 psi.
What can you spray with HVLP?
From a commercial perspective, HVLP spray systems are widely used in the automotive, marine, furniture finishing, and decorative industries where high-quality paints, stains, and finishes are used in large quantities all-day-long.
Can I paint a car with a 30 gallon air compressor?
That being said, most air compressors with an air tank capacity of 30 gallons and up can usually handle painting a car. If you’re painting a classic full-size car or want to play it safe, a tank of 60 gallons or more should be enough to coat the vehicle in a single pass.
Can you spray paint with a 3 gallon air compressor?
A contemporary 3-gallon (11.36-liter) air compressor can handle light-duty pneumatic tools, spray painting, small to medium scale inflating, dry cleaning, moderate sanding & blasting, some gardening, and farming tasks, and a plethora of DIY jobs.
What compressor is best for spray painting?
Best Pressure Air Compressor for Spray Painting—McGRAW 21-Gallon 175 PSI Oil-Free Vertical Air Compressor. With wheels and a handle, it’s easy to get pressurized air on any job with this 21-gallon McGRAW compressor. It’s another slightly larger tank that’s still fairly quiet compared to others.
What size air compressor do I need to run a paint gun?
A 15-20 CFM air compressor is a good match for a 10 CFM paint gun. A 6-8 CFM air compressor is a good match for a 4 CFM paint gun.
