Answer: 
To make a recommendation on an air compressor we would also need to know what voltage you are working with. I also have another question regarding to 3CFM @ 105 psi per. Does that mean per cycle? If you call 800-Grainger and ask to speak with Pneumatics Tech Support we can get these questions answered and pick out a compressor and dryer that would work for your application. Thanks for using Grainger Ask & Answer.

Is there a wiring diagram for this?

Also the electrician who is wiring this says it is a 3-phase motor which seems correct to me. But he says the pressure switch is single phase.

Any help would be much appreciated.
