You can run any system out of air driving air hungry tools. The 7.5 HP systems coming out these days are sort of BS in that a 5HP 1725 RPM motor is perfectly capable of doing the work.
HP is not a good measure of air compressor capacity regardless of the industry trying to use is as such. The important measure is output CFM.
IR is pretty famous for failures...
The pump, motor, and tank size are all important. The OP chose well.
The compressor is only the first bit in the system. You also need piping, filter, dryer and regulator. Then you need air tools. In my mind, the air system needs to be designed/built in a way that water has to end up either in the air tank or at the end of the system. That way it can be drained, or caught by the dryer. You destroy air tools by running hot wet air through them.
