2 stage compressors
I have starting looking around for a new compressor and wonder what is the benefit of having a two stage compressor vs a single stage compressor.
I know that you can have higher max pressure and higher working pressures along with greater working air flow.
But are there any other advantages?

2 stage compressors
Bambibasher, when I built my new house, I decided that I would finally have a decent air compressor. I ended up buying a 7 1/2 H.P., 80 gal, 2 stage upright. After years of suffering with a single stage 20 gal, I got what I wanted all along and have never looked back. I built a homemade sandblast cabinet and this thing will stay right up with it. I can be blasting wide open and this thing will kick on and recharge and shutoff. It keeps up with any air tool I have and even though you're not supposed to do it, I have cranked the pressure up on an impact and it was the difference in busting a bolt loose. When painting in the garage, my old 20 gal would struggle and overheat trying to keep up. If you ever plan to do any painting with the new HVLP guns, you will need the cfm output of a 2-stage. It all dedpends on what you are going to do in your garage, but a cast iron 2-stage will handle most anything you probably are planning. Also when you pipe up your garage, I recommend you don't use PVC piping but instead iron pipe. Later, Charles

bambi, high airflows are not exclusive to painting or sand blasters. Look at the air tool specs in a good tool catalog (snap-on etc.) my 1/2" impact and air hammer both use 12cfm @150 psi. My 3/4" impact uses 18cfm @ 150psi. The best single stage at the "box stores" can't provide 12cfm or 150psi. So instead of working a single stage overtime, everytime. Get a two stage and keep it for life.
