Ingersoll Rand T-30

[Ancient Iron]

I have a used upright I.R. T-30 compressor that was used in a Tire shop in Costco. I have it in my garage and would like to run a line to it and use it
It has a 220 v.three phase motor, I was wondering that if I change the motor to a 220 single phase would anything else need to be changed???

Lots of posts on just this process.

Possibly the mag starter, or the coil in the starter.

You’ll need to replace the motor, starter, pressure switch, and -depending on the RPM of the replacement motor- perhaps the motor pulley. You might take a look at connecting a VFD to the machine to make it run on single phase power.

You’ll need to replace the ...... pressure switch, ......

I don't think the pressure switch needs to be changed

I don't think the pressure switch needs to be changed

You're right, it doesn't. The switch is just 2 terminals that switch between open and closed, doesn't care if it's 3 phase or single.

I have a T-30 compressor that I changed to single phase. Motor and starter is all that I've changed.

When I bought my T-30, I bought a new 5hp Baldor motor (original was 3 ph) off ebay for a couple hundred and needed to replace the motor pulley. The pulley was purchased from McMaster.

Why change the starter? Use 2 of the 3 contacts and adjust or replace the overloads to the right size.

I have a few starters that are 3 or 4 pole running a single phase 220v motor at work

Well depending on the control voltage of the coil I guess
