T-30 model 71T2 compressor RPM Specks

by Harry
(Maine)

I have a Ingersoll-Rand compressor model 71T2 Serial Number 580888 and I am looking for the compressor RPM requirements.


No data on the motor anywhere or I could figure it out.

I am replacing the single three phrase motor with a single phase motor, but need the compressor rpm requirements so I can modify the motor pulley size as required to ensure the compressor is turning at the required RPM.

I have the I/R Instruction and parts manuals, but they do not address the compressor RPM.

Thanks,

Harry

Yeah, that's hard come by...

But maybe you can tell by looking at the motor:

Let us know - BTW, that's a 10 hp motor (if original), so you'll have to run it either slower or only to maybe 120 psi.
