Compressor cfm?

[Buddyc]

Im in the middle of rebuilding my dads garage inorder to help facilitate the restoration of my 66. Before my father recently passed away he sold off everything including his air compressor and air tools.
Im looking at compressors now and already have the 220 line in place. However im not sure what cfm I should target inorder to run air sanders and spray equipment. Or even how big of a tank I should have. I plan on doing all the prepwork and priming in house and taking it to my friends shop and using his downdraft booth for the final painting.
Although I usually overkill or things that I buy ( like some of us) I dont have that luxury at this time. I still have to buy new sanders and have to rebuild my guns.
This is one I saw but thought it may be too small
12.5 scfm at 45 psi
10 scfm at 90 psi
Maximum 125 psi
240 volt 60 Hz 1 phase
15 amp 5 hp and a 33 gal tank

No less than 10 CFM, 12-15 is better.
I found I needed a drier also.....that became very important.

mines is a 2 stage,35 cfm @ 125 psi..quincy 2 stage 5 hp 80 gallon tank..

you could get away with 20 cfm @ 90 psi and a 60 gallon tank..


make sure thease are 220 v single phase..

My compressor is similar, but only about $450.00 about 4 years ago when my old 25 year old compressor died finally. The little I use it, It's perfect.

If I had a grand to spend it would be easy choice. Cash is tight and I have SO much stuff to buy if I plan on being in the water by next year.

Then I would keep a eye on craigslist. Lot of cheapos, but occassionally you can find a half decent one at a good price.

do you have 3 phase?
If you do i would upgrade to it.
Air is the type of thing you eventually end up using all of it.
bigger is better will last longer
buy the biggest cfm you can afford with your electrical service.
buy the biggest tank you can fit.
surge tanks within 10' of your work is great.
a screw type compressor is the way to go over a piston.
a drier is needed.
my 2 cents 35 years of dealing with comperssors.

I can appriciate your know how about compressors, and I wish I could just go but whatever I want. Im scouring craigslist and put the call into my friend that is still inthe bodyshop biz to see if anyone is cleaning house. Im going to be spending over 5 grand in the next month for prep and paint material and my motor. I know that my longboard will take the most air to run continuiously. Maybe its bad to say but I need something to get my by...but it has to be able to run my stuff

Just checked Hutchins site and my dual action air board needs 11.8 cfm @ 90 to run right

There you go.
It's highly unlikely you'll ever be running two tools at one time.

[thescooter]

please go with your budget.
the only thing you can do is use some electric hand tools when you are using a high CFM air hand tool. this will help lowering your load on your compressor to give you a longer compressor life.

Hey guy my garage compressor is a 8 hp-2 stage running with two tanks and filters and if you can afford a bigger compressor , other then five HP .........go for it !!! Buddy , just a quick mention stay away from anything that is not belt driven (junk) and most places who sell just compressors .......most likely will have a good slection of used ones and in fact i purchased a 12 HP/ 3 phase a while back for a grand .
