Next Generation RS 4-11 kW Rotary Screw Compressors

Ingersoll Rand’s 4–11 kW rotary screw compressors deliver the reliability, efficiency, and serviceability that small businesses and industrial users depend on. Built with fully integrated, proven airend technology and validated through comprehensive performance, thermal, and durability testing, this platform provides consistent, high‑quality air with confidence you can count on. A best‑in‑class control system, optional IoT connectivity, and a compact design that fits through a 36-inch doorway ensure easy installation, smart operation, and reduced downtime. Designed as a total air solution with available integrated dryer configurations and long-life consumables, this compressor offers lowered operating costs and a simplified ownership experience.

Additional Options:

  • Variable Speed Drive (VSD) model that automatically adjusts the compressed air outlet to achieve the highest efficiency for your operation, minimizing energy use under any load. 
  • Total Air System (TAS) with refrigerated dryer and filter system for clean, dry air in a single package.
  • Increased Efficiency: Advanced airend design integrates key components to reduce leak paths, improve reliability and VSD turndown on variable speed models
  • Leak-free Operation: V-Shield Technology provides a totally integrated, leak-free design featuring PTFE stainless steel braided oil hoses and O-ring face seals
  • Improved Productivity: Ingersoll Rand’s touch screen controller includes an intuitive high-resolution display with web-enabled communication and control
  • Compact Footprint: Vertically-stacked drive components reduce footprint and allow for easy maintenance
  • Enhanced Reliability: Sequential Cooling System significantly improves reliability and serviceability by providing cool clean ambient air to key components
  • Ultimate Energy Efficiency with VSD: Variable speed drive (VSD) automatically adjusts its compressed air output to achieve the highest efficiency for your operation, minimizing energy use at any load
  • Optional Total Air System (TAS): Includes a refrigerated dryer and filter system. Clean, dry air in a single package that minimizes installation costs, space and features improved ISO air quality
