There are HVLP guns that require their own unique compressors. Lane |

Is this going to be adequet for auto painting, please help! I'm trying to remember from my auto painting days. My shop had a 10 cfm@100 PSI, 10 hp, 100 gal tank. I used high pressure spray guns to do basecoat/clearcoat jobs. The compressor could just keep up to me. If anyone else was using air for sanding, I could drain the tank before I had one coat on. I would have to let the compressor catch up between coats. Are you hobby or commercial painting? If it's for your hobby, you can let the compressor catch once in a while. If you are making your living off the output of your paintbooth, you would best be advised to get engineering help from DeVilbiss or one of the other big paint companies. You have other issues here too, like clean and dry air as well. BB |

My compressor is about 7 CFM @ 90 psi. My gun is a cheapo HVLP gravity feed. The compressor will not keep up with it. HVLP is the way to go, quality guns are a bit more efficient, but I think you need to shoot for 13 CFM @ 90 if you have more than one car to do or if perfection is your goal. Get the specs on your gun, get a compressor to meet them. Rex in Fort Worth |
