So I just bought this...



and this:



Is not cutting, AT ALL.

My D/A Sander requires 5 CFM...

What is the smallest (cheapest) compressor that will keep up with Sander?

I've seen a bunch of compressors that say: 6 SCFM on them...
Is that adequate?

Thank you so much!

you need 25 gallon min. and still it wont shut off youll be spending time waiting to refill tank d/a run alot of air most of the compressor rate inital start up and quickly dieout plus the noise of the oilless compressor will drive you mad ideally 100 gallon oil compressor (kind with external belt) now you talking 220 volt no win situation it will take a LONG time to da a car that size sorry ( you need volume ie. tank size no residential compressor will keep a da happy with just the compressor) also you have a min and max pressure the tank starts and stops so accually you only use a couple gallons of air before it starts again so without spending hundreds of dollar its not possible

Yeah that little toy compressor is not going to do it at all.

I have an IR 60 gal, 220 volt, 11.3 cfm @ 90 psi compressor and it just barley gets the job done when using high air draw tools like the D/A sander.

You need to look at what pressure the cfm is at. The D/A sander needs 90-100 psi air pressure to run.

Alot of compressor companies will show you the big bold 6.5 cfm rating to fool you.. Look close and you will see that's at 40 psi or so

To work pretty good you need a min of 1.5 X the cfm as what the tool says really.
To work really good you need about 2.2 X what the tool says

Your D/A sander says 5 cfm, you need atleast a compressor that puts out 7.5 cfm @ 90 psi, and that's bare min. To work like it should you would need 11 cfm @ 90 psi

Here is what I recommed
$680 http://www.maxtool.com/ingersoll-ran...ght-11-3-cfm-s
That is the same one I have. I had mine going on 15 years now.

If you can only go with 115 volt units

If you can swing the price and run 220 volt line to it, you will NEVER regret getting a 220 volt, 60 gal compressor.

I have a whole host of air tools that I run on mine almost daily that a small unit would not be able to run.
700 ft lbs impact
3" cut off tool
die grinder
6" d/a sander
in line long board sander
drill
body saw
rivet gun
4" angle grinder
sheet metal nibbler
paint guns
air hammer
nail guns

I don't think I can swing a $680 compressor....

What about electric D/A Sanders?

if you plan on doing your own work on the car 60 gallon one like above you wont regret it 230 volt otherwise have a shop do the work will be alot more invest in the future

You could scan local ads for a nice used one,

Most small compressors are between 3 to 5 psi per second the low number is maintained pressure and the high is constant run with time to build pressure

Just get a 110 volt orbital sander and some good sanding disks
I did my car with a orbital 220 grit to 400 then wet sanded with 400 then 600

Came out great by the way

I bought a 29 gal compressor from harbor freight and regret it. Get the biggest you can afford.

Also, google linking/combining 2 compressors. It may be a cheaper option for you.

Is this what I need?

Well,
I've already bought a Air DA Sander, and I'm going to need a good compressor for spraying primer....

I know a few guys that use electric. Thats what id do if you dont want to buy a compressor...

If that compressor was local it would be mine.

Looks pretty good to me. I have one similar, painted a few cars with it.

Both of those compressors will get the job done real well

I'd buy that now if it were local to me. Good luck with your paint project!.
