Contrary to popular opinion or intuition the size of the tank has no bearing on the CFM output of the compressor. You must look at the specs of the compressor for it's CFM rated output and at what pressure and compare it to the spec requirement of the equipment you want to run. I do not know the CFM required to run the Aro tool. You can't even go by the size of the motor. The CFM output of a compressor is affected by the size of the cylinders, the speed it is run at, the pressure it pumps to, and the # of stages. This is assuming it is a recip. Rotary are calculated differently. BTW a recip is only rated to 75% of it's capacity so it has some period of cool-down and you can have only so many start-stop cycles per hour. This is where the size of the tank starts to matter. Anything more than 3 HP and you should consider a 3 phase motor which is hard to do in a house. You have to also consider some way to get the water out of the air or you will quickly ruin that expensive Aro tool. All in all it is not the "best" way to go in a house for a tool that you will not use often. IMHO a flexible shaft-driven tool running on an electric motor makes more sense.
