how much CFM should a compressor put out?

scratch that. theres another compressor setup that puts out 12.4cfm at 40 psi and 10.2cfm at 90psi.

that should be fine for just about all the air tools. but what about spray guns. looking at sata and devilbiss, most of the cfm their guns need is around 15, but the psi is around 20. so would this compressor be good? it will be around 100 gallon tank too.

please let me know.

no one has compressors at home?

My comrpessor right now is only putting out around [email protected] does what I need as far as painting goes, but It's not enough for air sanders


For spray guns you want 10+ or as close to 10+ [email protected]

For air tools such as DA's and other sanders you'r looking at least 15 [email protected]

Also look for tools with lower cfm ratings.....I know there are guns that use as little as [email protected] and DA's that run at [email protected]

thank you for your help

mine puts out 15 cfm at 175 psi. runs my dynabrade da's with no problem. the air in the tank never drops below 140. i can run the da all day and i'll always see 140 or more.

sounds like that thing cost a couple thousand to put out those numbers

ok let me ask you this :biggrin:


how many times does it turn on if you are da sanding for an hour?????

i have no idea. i havn't even paid attention to that. it does go on and off though. all i know is that i don't ever run out of air.

Your air tools will be rated at a certain cfm. If your tool takes more cfm than the compressor makes then simply its' not big enough. I had 1 that would keep up with my tools but once it kicked on it would stay on while the tool was in use. It was a 80 gallon 6 hp single stage. $500.00 new. If you want a decent one then go with at least a duo-stage. I upgrades to a triple stage. it was worth it if you use them alot.
