[Old Ingersoll Rand Compressor]

Thank you JMG. Have been on many different sites. But I think a call definitely will help.

[Old Ingersoll Rand Compressor]

I just acquired an old Ingersoll Rand verticle 80 gal shop compressor. I have some questions setting up. Here are some specs I got from the tags.

Pump:     TYPE  30

                 Size  3 & 1 3/4 x 2

                 Compressor No.  3OT    3330

Motor:     General Electric Repulsion Induction Motor

                 Type SCR  2HP Single Phase

                 60 cycle- low voltage          /        50 cycle high voltage

                  V110-A.19 / V220-A. 9.5              V110-A. 20.8 / V220-A. 10.4

First question I had, it looks like 10 wire coming out pressure switch. I assume that would be hooked up to a 30 amp breaker. And I also assume that the A. is for the amps. But confused about the low amperage numbers. The other question I had I have no idea what the maximum pressure would be I see nothing in that regard. And last if I install a regulator, oiler do they need to be the same size pipe that I will use for the air supply around the shop (3/4"+ gal)

Any help in this area would be appreciated.
