I have a I R 80 gal, 5 hp , dual stage compressor. Burned up the motor using sand blaster. They gave me a new one and I make sure to give it a break while using it now. The electric motor repair shop I visited just shook his head when I brought the motor in. He said he had converted one of them to the lower speed motor for a guy as IR, like most , uses the high speed , light weight motor to control cost. I don't remember the exact rpm but they are something like 1740 vs 3480, electricians would know.

Yep, the pump isn't the only place they cheap out. IR tends to uprate their smaller pumps by putting a 3hp pump on a 5hp compressor then running the snot out of them with a 3450rpm motor. Then they have the gall to call it a 100% duty cycle machine. That IR synthetic oil must be some good stuff. i put one of these in the control room of a gas well about 12 years ago. It was replacing another 3hp-5hp compressor that had failed. I cringed when I fired it up....
