My small shop is looking to get a new air compressor, and we want to be able to run 2 DA’s at the same time. The DA’s use 17 CFM at 90psi Does that mean that I need a compressor that provides 34 CFM at 90 psi? Any help would be greatly appreciated.

Thanks!

Running two DA’s will require a LOT of volume. So when you look at compressors, make sure you get one with a big enough airtank to handle what you’ll be doing. I’m thinking you’re gonna need something in the range of an 80 gallon tank (or bigger)

Yes. Also large enough supply lines to move that amount of air. I agree with JoeInGa that an 80 gallon tank is the way to go. This decreases how often the compressor has to run.

Two stage, 5HP, 120 gallon with a flow of 34CFM @ 90psi MINIMUM.

Not cheap and if it were me, I would get two units for redundancy and less wear and tear on the one motor and compressor.

You got it. Dual Action

P.S. I know everyone is used to seeing air driven DA Sanders in a body shop but they are terribly inefficient.

I would consider using electric DA Sanders. Just as effective and use far less electricity.

I agree with timbertailor. Except for a few very special applications (such as a nail gun or paint sprayer), I can’t understand the love so many people have for air tools.
