You will need at least one regulator and a water trap in line before the regulator. These are not costly. A regulator allows you to set the correct air pressure for the tool you will be using (say, 80 PSI) instead of tank pressure (say, 175 PSI).
I found a nice air powered air gun at a local hardware store. At first it seemed just perfect. I was about to buy it when I noticed on the little description card that it was not recommended to be used with a compressor smaller than 6 gallons. Dang! The portable air compressor I had was only a small 2 gallon pancake compressor. That just wouldn't cut it. I had to buy a larger unit so that I could get the gun, so that I could finish the house project. See how this goes.
I hope this information has been useful to you. Buying an air compressor for your woodworking shop can be a fairly expensive investment when you consider piping, regulators, hoses, water traps, wiring and electricians. You will want to buy a compressor that is capable of the tasks you will be using it for but no more than that. Purchasing the wrong air compressor can be a very expensive mistake. My motivation in writing this has been to give you the knowledge you will need to select the right one.
