Ok we had a post of "Air Needed". So now I have a question. What air sanders do you use? My compressor is 33 gal and 2 hp. Didn't go with a larger one because of money and size. Just don't have room for the big monsters. I have read on some of these air sanders like the Grex that it takes 8 cfm. I was looking at a Ingersall Rand that says 3 cfm to run at full load and collet size is 1/4". I know without a bigger tank it will run more often. I was just wondering for those that use air sanders what do you use?
