PAINTING WITH 20 GAL DEVILBISS AIR COMPRESSOR RATED AT 13 CFM @ 40 PSI ?

[waid302]

Hello,

My name is waid and I am a new member here.

I am looking to paint my old Falcon in my Garage. Most of the HVLP paint guns seems to require about 13 CFM @ 23 PSI inlet. I was thinking about buying entry level 60 gallon compressor like the one they are at Menards but its rated 3.7hp with 13.4 CFM @ 40 PSI. My old 6.5hp DeVilbiss twin pump Air Compressor is rated at 13 CFM @ 40 PSI but its only 20 gallons.

I just need to paint this one car.

Is my old DeVilbiss adequate for HVLP paint gun?

I don't have any paint gun yet. Not sure how accurate it is but I did a quick test. I set the regular at 30 psi and used a blow gun continuously. The tank pressure never dropped below 120 psi and the compressor cycled but did not ran continuously.

What do you think ?

Waid

Thanks

Compressor is too small to paint an entire car. You'd have to wait and let it build pressure after painting each panel on the car, so you'd never get good flow out from panel to panel. AND the compressor would be working so hard, it would put a lot of moisture in the air supply, that you probably couldn't filter out. Ruin the paint job!
