The NorthStar Air Compressor Pump requires a 4 HP electric or 5.5 HP gas motor. The pulley size would depend on the RPMs of the motor. To determine pulley size you would take the pump RPMs (1396) and multiply by the flywheel diameter (10.5). This gives us a total of 14,658. You will then divide 14,658 by the RPMs of the engine to determine the diameter of pulley needed.

I have provided a link below to the manual for the compressor pump. In the parts explosion on page 18, the 3 way fitting shown will connect the brass tube that connects to the unloader valve.

This NorthStar Air Compressor Pump would have an output of 14.5 CFM @ 42.9 PSI and 14.2 CFM @ 57.2 PSI. It would require 1396 RPM for that pressure.

There is only a max RPM for this pump. The recommendations listed in the manual for the engine/motor size and fly wheel diameter should be used for proper use.
