How much CFM do I need for spraying?

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.

What is the best air pressure for a spray gun?

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.

Is 10 CFM enough for spray painting?

While some air spray guns have a rating of lower than 10 CFM, we’d recommend your compressor CFM for spray painting is at least 12 CFM. For professionals, this figure may need to be higher – the important thing is you’ve checked your spray gun’s CFM requirements and chosen a compressor that exceeds that figure.

How many psi do you need 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 many gallons of air does it take to paint a car?

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.

How much pressure does a LVLP gun need?

(LVLP) Air Pressure Setting (Low Volume Low Pressure) The normal scfm consumption for LVLP guns are about 5-7 scfm (cubic foot per minute) and volume of air used at 40 PSI.

Can you spray metallic paint with LVLP?

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 does a LVLP spray gun work?

LVLP spray guns are better than HVLP spray guns because they produce few defects. This is because air bubbles can be produced in high volume which can cause a lot of defects. The LVLP uses low pressure and a thin nozzle which allows a low volume of paint to be pushed out of the gun.

What CFM is needed for 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.

What causes clear coat to orange peel?

The name orange peel is given by the resemblance of the final paint finish to an orange peel. This problem is caused by the lack of stretching or levelling of the paint, resulting in a deformed surface and in an increased thickness of the final coat.

How many CFM does a HVLP gun need?

How many CFM do I need for auto painting?

We’ll discuss psi below, but a high-volume, low-pressure (HVLP) compressor is usually sufficient to complete an auto paint job. Look for two-stage compressors that deliver close to 20 CFM. Air pressure: As mentioned above, pressure (psi) is less important in an air compressor for painting cars than CFM is.
