The Ingersoll Rand RS11-22kW and RS15-22kW are the first compressors in the Next Generation R-Series line designed for small commercial operations. The RS15-22kW unit includes premium features out-of-the-box and is available with a fixed-speed or variable speed drive motor. This model debuts an air-end design that produces 20 percent more airflow compared to previous Ingersoll Rand compressors of this capacity, resulting in more energy savings, according to the company. The RS11-22kW houses a redesigned cooling system and increases energy efficiency up to 12 percent compared to legacy UP6 compressors, the company says.
