Ingersoll Rand RSa Series Rotary Screw Air Compressors

When it comes to reliable compressed air, businesses need efficiency, dependability, and a system that’s designed for their specific application. That’s exactly what the Ingersoll Rand RSa Series rotary screw compressors deliver. Engineered as the next evolution of Ingersoll Rand’s proven RS line, the RSa Series provides high performance, low total cost of ownership, and simplified operation for industrial and commercial environments.

If you’re looking for a fixed-speed rotary screw compressor that balances efficiency with rugged reliability, the RSa Series is designed to meet your needs.

Overview

The RSa Series is Ingersoll Rand’s updated fixed-speed rotary screw compressor line for 20hp, 25hp and 30hp air compressors. The RSa series offers improved performance and technology compared to the previous RS Series. With enhancements in airflow, efficiency, and serviceability, these compressors provide a dependable solution for shops and facilities that require continuous, steady air supply.

The RSa Series is ideal for:

  • Manufacturing plants that require 24/7 compressed air for production lines.
  • Machine and auto shops that need steady, reliable air for tools and equipment.
  • Food and beverage facilities where air quality, reliability, and uptime are critical.
  • General industrial environments with consistent, predictable air demand.

If your operation depends on compressed air as a backbone utility, the RSa Series is built with your uptime and efficiency in mind.

XE-110 Microprocessor Controller:

Each RSa model comes equipped with an Ingersoll Rand Xe-Series controller, offering easy-to-use monitoring and system diagnostics. This controller helps operators identify potential issues before they cause downtime, while also making day-to-day operation more intuitive. Benefits of the XE-110 controller include:

  • Safety mode – Jog Motor and Voltage Test
  • Phase monitor to ensure proper motor rotation
  • USB Flash drive support – extracting log data & controller programming
  • AirSmart RS485 Modbus Communication Protocol
  • Drive Motor Temperature Monitoring

Operator-friendly design

The RSa enclosure is engineered for reduced noise levels, creating a safer and more comfortable workplace environment. Maintenance is also simplified with accessible service points and fewer moving components, ensuring faster service intervals and less downtime.

Cost of Ownership

By combining efficient performance with durable construction, the RSa reduces total ownership costs over the lifetime of the machine. Reliability means fewer unplanned repairs, while energy savings and streamlined service keep long-term operating costs under control.

Energy is the single largest expense for most compressor users, and the RSa is designed to reduce that burden. With efficiency-focused design improvements, many operations can expect meaningful reductions in utility costs compared to older or less efficient compressors. In some cases, businesses may also qualify for local energy rebates or incentives when upgrading to newer compressor technology.

Optional Refrigerated Air Dryer

  • An optional refrigerated air dryer can be pre-installed with the compressor. The ‘TAS’ or “Total Air System includes a refrigerated air dryer and oil removal coalescing filter. The TAS package occupies less space, costs less to install, and delivers high quality compressed air to maximize operating efficiency and reduce costs

The Ingersoll Rand RSa Series rotary screw compressors represent the latest step forward in fixed-speed compressed air technology. With improved efficiency, simplified service, and industry-leading reliability, they provide an ideal solution for businesses with steady air requirements.
