Air compressor help

That compressor is just barely adequate for an impact gun and not adequate at all for a die grinder, DA sander, spray gun or any other air tool that uses continious air supply. Also, to really get the full power from an impact gun you need to supply it with at least 125 psi even though they are rated at 90 psi so you want to look at the scfm needs and the ability of the compressor to supply that at 125 psi.
