Working around compressors my whole life, I’ve learned to deal with the loud and irritating sound of typical reciprocating (piston) compressors. What a dream and joy it is to stand near an Ingersoll Rand Rotary Compressor installation and still have a normal conversation. In addition to a quieter experience, the Ingersoll Rand R-Series rotary compressor delivers additional performance as well.

Ingersoll Rand Rotary Compressor Installation and Startup

We recently received the Ingersoll Rand R4i rotary compressor for review and testing at our STR metal and auto shop. Our video walks through the installation, setup and startup of the R4i compressor. Unloading the IR Rotary compressor was a bear. This R4i with the Total Air System (TAS) weighs in at about 800 lbs. With an engine hoist, straps, chains and a couple floor jacks, we got the Ingersoll Rand rotary compressor nestled in the corner of the shop.

R4i Rotary Compressor Wiring

The R-Series line is available in single or 3-phase power, 208V, 230V or 460V. We ordered and received the R4i compressor configured for 230V single-phase power. After installing a 50A breaker in the panel, we ran 8 AWG 8-3 wire from the panel to the compressor in seal-tite flexible conduit. We wired up 2 legs (wires) of power to L1 and L2 inside the door of the Ingersoll Rand R-series compressor, hence attaching the ground wire to the ground lug. Wiring is made very simple with the labels from Ingersoll Rand, although we still recommend a licensed electrician to complete this task.

Ingersoll Rand R4i Startup

With wiring complete, it’s time to fire up the compressor for the first time. Hit (touch) the green button, and the Ingersoll Rand R4i roars to life – more like humms to life. You first hear the whisper of the Total Air System drier and fan kick on, then the compressor comes on. Even with the unit fully running, engaging in conversation nearby is not uncomfortable.

Total Air System (TAS) by Ingersoll Rand

In addition to the rotary compressor, Ingersoll Rand added the Total Air System (TAS – sounds like TAZ). This adds a refrigerated drier, conditioner, and filter. This ensures clean exit air for painting, sanding, and any uses for clean compressed air. We will have additional posts and videos to follow, including air line install, the actual review, and more.
