I'm looking at upgrading my current useless compressor to one that will let me sand, buff, and spray without having to wait for it to recharge. What size tank, HP motor, and CFMs would be needed?

Looking to spend $600-800 for a used one. This caught my eye, but not sure, I really don't know much about them.

thanx

The single biggest factor is usable CFM at 90 psi or better. Check the airtools that you intend to use, and see what their requirements are.

the one you looking wont do the job jor you,,i would up your price and look for a bigger one..18 cfm and up to run your air buffer..

And what number of CFM falls into the range of sanding buffing?

try to find a used Quincy 5 hp, a twenty yr old maintained quincy will outlast any of the big box name brands by decades...
i picked one up last year for $100 been running ever since.

look for a rotary compressor, they last forever and put out a ton more cfm than a recip.

a 5 hp should be more than enough

You will need a tank probably, just use your old compressors tank.

If it's not marked on the tool, check the owners manual or the manufacturer's web site; there can be a very wide variation.
