I think a better question is how many CFM you need.
You can use a smaller compressor but it will run and run and run.

As big as you can afford. I would say at minimum 60 gallon. Cut off tools and spraying paint uses alot of air.

I have a 3 HP compressor and an 80 gallon tank and at 80psi the volume is barely adequate. I plan on upgrading to a 5HP compressor and keeping the 80 gallon tank.

Is there somethign wrong with this? It's at a 'local' inventory reduction sale. Seems like a great CFM (13.3 at 90lbs), but only 60 gallon. Not bad I guess? Not sure what to look for?

I have a small compressor with a 5 hp motor about a 20 gal tank and it runs a lot when useing a lot of volume in my tools. It gets really hot too.

Not bad for the money, but 13 cfm is not much. That is about the minimum you could live with and use air tools.

What would the recommended CFM be at 90lbs? I have 5.6 now in a small portable 5HP unit. I thought 13.3 at 90 would be a nice upgrade?

I was going to say a big muther. I liked some one elses response "Get the biggest one you can."
I had a Sears 30 gal. It worked but would not get much rest or even get past 125 PSI (week)
I upgraded to a 80 gal 220 dual head and love it. That one pumps up to 185 psi. Do you realize how torkey a 1/2 gun is at 185. :yes:

You need a 60gal 5 hp. 18,5 cfm air compressor to fill your needs. Eagle air company :hurray:
makes one,its around $700.00 dollars,I have one and its great.A 3 piston set up. :D

I've got an eerily similar model to the one posted in that ad. (Same exact specs). It can keep up with my die-grinder, paint gun (14.3cfm @ 35 requirements), and any other tool.

The downsides: Single phase, only 125psi, and probably too low for a DA (haven't tried).

you need atleast 18 cfm to run air tools, minimum. I learned the hard way and went thru 3 compressors before getting a 7.5hp 23cfm Ingersol Rand.

At least a 80 gallon tank. If you use impact and air ratchets, then you need to figure minimum of 125 psi. preferably about 150 psi. I know that the tools are rated at 90 psi, but they are gutless at 90 psi.

Buy the bigggest one you can get. The best ones will be 2 cylinder 2 stage min. of 5hp and 220 volts the tank size should be at least 80gal. vetical tank. The other item is to make sure all your lines are at least 1", why would you have an oultlet of 1" then neck it down to about 3/8" with a little regulator (1" regulators are not cheap). Also buy an automtic dump for the bottom of the tank to keep the water out and save the tank. When yo get ready to set it up put it in the cornetr and we hooked up a fresh are intake vented from the outside using a chevy truck air filter under the edge of the roof overhang.

Good luck wro87

Also look for one that is NOT internally oiled-they wear out and eventually don't build up pressure fast enough- they're cheaper, but then you end up getting a 80 gallon 5 -6 hp one for $900 anyways since the first one broke, so spend your money on a good one and you'll be WAY ahead...

So, make sure you have a provision to add oil to it- some are internally oiled and are not servicable...

It wouldn't hurt to take a look at this. http://www.1969supersport.com/draw1.html

A little more here, if you sandblast the bottom of the body, if you can get a compressor that will pump up to 175 lbs, then you have a usable 130 or so lbs of pressure.

When you try to clean the sand out of the body, you will need the extra pressure.

I usually set my regulator so I have about 90 lbs at the air tool, and it is really hard to get the sand out of these bodies at that pressure.

When I max out the regulator it works a lot better.

As long as I'm on a roll, might as well put this one up, the tool for cleaning out a body, its on this page. http://www.1969supersport.com/restore7.html

I AGREE as much as you afford or can barrow from the wife

Or wait until she goes to bed and steal it out of her purse, or get her drunk, and accuse of her losing her money, or, ah, nevermind.:)

i picked up a 2475 7.5 hp 80 gal IR on ebay for 1200 new. it took me about a year of looking, but it was WELL worth it. i can be running a tool or a gun and it will come on and turn off and i wont even have let my finger off the trigger.

At work the company just bought a new compressor. Here is the manufacturer's brochure. The model at work is TK-150120. An awesome compressor, much too large for a home shop.

rubadub what the heck is that tool for getting sand out made of????

Its just a regular short type blow gun, with the tubing over the end of it, and wrapped in electrical tape.

This is the tool of the week. I use this to clean out the sand in the floor supports. I've tried different sized tubing and after trial and error, this is the biggest you can use and still get in there. It will go half way in the rocker panels, so it works pretty good. The tygon tubing on the end is 3/16" i.d., 9/32" o.d., 24 inches long. Then there is another 14 inches to the end of it. I used 5/16" i.d. quick-disconnect on all of my tools, spray guns included.

Same picture as above. Taped to number 9 wire to reach inside the trunk, by the back seat, etc. You will have to take the number 9 wire back off to get inside the floor supports and rockers.
My compressor pumps up to 175 lbs. so I turn my regulators all the way up around 160 or so, if you try to blow this stuff out with 90 lbs. of pressure, it will be a lot harder to do.

Like this one.http://cvfsupplyco-store.stores.yahoo.net/airblowgun.html

I really appreciate it... Thanks!!! I just sandblasted the 66 Chevelle I own today. Gonna clean out the cracks tomorrow with my new "Tool"...
