I got a spray gun and its rated at for 30psi inlet 10 psi at 13 cfm.

Will a 3hp compressor with a 30gal tank handle this

Well Jan, since you can get about 4 CFM of compressed air at 90 PSI for each horsepower of electric motor size on the compressor, your compressor should, theoretically, give you about 12 CFM at 90 PSI.
However, if you are running your 3 HP compressor on a 120 volt supply line, then you sure are not getting that 12 CFM at 90 PSI, since, in my opinion, there isn’t enough power in a 120 volt line to power your compressor motor enough to give you that flow and pressure.
Why not have a look at some of the pages linked under CFM / SCFM / Flow / Pressure Issues on the sitemap page for much more info?
Anyway, depending on what you are doing with your spray gun (besides painting that is), I mean, if it is air brush work with intermittent use, and you have dialed your regulator down to the minimum operating pressure for the gun that gives you the spray you want, you will be able to work with your 3HP compressor. You will, depending on how much spraying you want to do at one time, likely have to stop periodically and let the compressor catch up.
