The all-new ES Series 55-110 kW oil-free rotary screw air compressor offers an optimized total package for the lowest total operating cost with Class Zero Air. This makes them ideal for applications that demand the highest oil-free air quality. The ES Series features a best-in-class footprint, 34% smaller than previous models and up to 50% more space-efficient than other compressor brands. See all the benefits:
• 100% oil and silicone-free air for mission-critical applications
• Best-in-Class Flow and Efficiency:
• Exceptional Reliability – Optimized Air end Design
• Unmatched space efficiency:
• Real-Time Data Visibility & Insights with Helix™ Connected Platform
• Enhanced user-experience via Next-generation Xe Pro Series Controller
Our 15–37 kW Eh Series oil free air compressor delivers the same proven reliability as larger models, offering 100% oil‑free performance, low vibration, and long‑life compression elements. The single‑stage, direct‑drive compressor uses a water‑injected system for superior cooling, lubrication, and sealing. An optional variable speed drive maximizes efficiency and turndown.
The E‑ne Dual Direct Drive platform delivers up to 13% extra power savings compared to conventional oil‑free variable speed compressors. Its innovative dual‑motor design with a “digital gearbox” continuously optimizes air end speeds for maximum efficiency. Water‑cooled air end jackets further enhance performance, while direct coupling removes the need for a physical gearbox
Our 90–160 kW E‑Series oil‑free rotary screw air compressors deliver up to 14% higher efficiency and 35% more turndown than previous model generations thanks to a fully redesigned air end and advanced package design. With both fixed‑speed (IE4) and best‑in‑class variable‑speed (IE5) models, the E‑Series offers maximum output and the highest airflow of any oil‑free 160 kW compressor in its class—while significantly reducing energy costs.
The E Series 200–355 kW delivers 100% oil free, Class Zero–certified air, ensuring maximum safety for sensitive production processes. Its advanced design provides up to 8% higher flow and significant energy savings compared to other models on the market, lowering total operating costs. With both fixed speed and variable speed models, plus air or water-cooled options, the series offers exceptional configuration flexibility. A redesigned, high efficiency air end and robust cooling system delivers unmatched reliability even in demanding conditions.
Nirvana 37–75 kW compressors offer exceptional value with a fully integrated Variable Speed Drive and advanced HPM motor technology for top‑tier efficiency and reliability. They maintain a near‑unity power factor across the entire speed range and provide wide turndown with rapid start/stop capability—eliminating wasteful unloaded running.
Sierra 37–75 kW fixed‑speed compressors deliver 100% Class 0 oil‑free air with a robust, proven design for continuous, dependable operation. Standard features include a high‑efficiency TEFC motor, star‑delta starter, NEMA 4 electrics, advanced filtration, and high ambient performance up to 46°C as standard, optionally expandable up to 55°C.
Around 94% of the energy consumed by an air compressor is converted into heat. Without a heat‑recovery system, this paid‑for energy is simply released into the atmosphere - forcing your facility to use even more energy to remove it through cooling. At the same time, many plants spend substantial resources generating hot water, space heating, or steam.
Heat Recovery captures this waste heat and turns it into usable energy, reducing overall consumption and operating costs.
Recovered heat can be used throughout your facility - for heating process water or air, preheating steam systems, producing sanitary hot water, or supporting any application that requires heated or preheated water.
With a heat recovery system from Ingersoll Rand, the heat generated by the compressor can be re-used, providing the following benefits:
✓ Significant savings in energy costs
✓ Extremely short payback time – typically less than a year
✓ Lower CO2 emissions
✓ Turnkey solutions
✓ Easy installation and operation
✓ Small footprint
✓ No impact on the compressed air supply
✓ High reliability
We will assess and propose the best oil free compressor to lower the total cost of ownership of your compressed air system, maximizing the productivity of your operation.
Includes air dryers, filtration, controls, installation, and maintenance to ensure long-term reliability and consistent performance.
Take the Next Step Toward Reliable, Oil Free Compressed Air
Ingersoll Rand’s oil‑free solutions use technologies that fully separate oil from the compression process, offering continuous Class 0 air and reduced filtration requirements. Their systems support reliability, long equipment life, and compliance with strict industry standards.
They compress air without injecting any oil into the compression chamber. Bearings and gears that require lubrication are sealed and kept separate from the air stream, ensuring the delivered air stays 100% oil‑free.
