For a quality HVLP Spray Gun you can often need up to 20 CFM of air. If you are using a Conventional Spray Gun you may not need as much air as HVLP requires a High Volume of air (HV) especially compared to conventional spray guns, but a conventional spray gun can still use 10 – 15 CFM.
How many CFM 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.
What size air compressor do I need for a paint gun?
For small projects or single panels, your Air Compressor should be rated at 100% of the CFM required by your paint gun. If you’re spraying a whole car, you’ll want 150-200%. For example: A 15-20 CFM air compressor is a good match for a 10 CFM paint gun.

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 is the best psi for spray painting?
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.

What is the minimum size air compressor needed for painting 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.
Can you paint a car with a 3 gallon compressor?
ByBrittney. For a comprehensive buying guide, visit AirCompressorsUSA.com The most basic specifications of a top-quality compressor are usually 30 gallons per outlet, have a standard blade CFM rating of 10 lbs, and often operate with paint guns. They can all be assembled in no time at all and they can paint any car.
How many gallons of air does it take to paint a car?
