I am looking for a good air compressor to use around the garage for items like a ratchet gun, to inflate tires, and to use with a nail gun (some framing and some finish nailing). What size (hp and tank size) is sufficient for me? I have been looking at about an 8 gallon - either *****, Campbell Hausfield or Porter Cable. Do I need one that big? Thoughts?

Thanks!

You need to look at the maximum pressure requirement of your tools and the cubic feet per minute necessary to drive them. Paint and texture guns, sandblasters, grinders and most rotating tools have a high volume cfm and low pressure requirements while nailers need 90 to 100 psi and low volume. Look at the compressor rating to see what the output is in both pressure and cfm.

If you are looking a oiless piston compressors, keep in mind these are extremely loud. If you will be working in proximity to the compressor, consider a oil (belt drive) pump. These generally have higher cfm outputs and slightly lower pressure ratings. The tank volume is simply reserve air that can minimize cycling of the compressor pump. The pump rating is much more important. Large tanks are heavy and make the unit less portable. 8-gallons is not much reserve, but is very portable, but you need to have adequate pump capacity to drive the tools.
