E-Series Oil-Free Rotary Screw Air Compressors 15-37 kW

The E-Series oil-free rotary screw compressors utilize state-of-the-art design features to achieve unparalleled energy efficiency. Uncompromising in the superb reliability you expect from Ingersoll Rand, these compressors provide continuous 100% oil-free and silicon-free air. E-series offers an optimized total package for risk free operation at a low total operating cost. 
  • 100% Oil-Free and Silicon-Free Air: Tested and certificated by TÜV. Leverages purified water lubrication to cool and seal the compression process. Contamination is eliminated due to zero presence of oil inside the compressor. 
  • Energy Efficiency and reduced total cost of ownership: Water-injected lubrication system enables superior cooling of the compression elements, providing leading efficiency and reducing maintenance costs by eliminating the need for costly consumables.
  • Enhanced Reliability: Innovative compression design with few moving parts and low rotational speeds enhances product life; reverse osmosis membrane filtration system for water purification allows trouble-free operation.
  • Ease of Use: Superior noise control features and small footprint ensure a safe, comfortable working environment and reduced installation costs
  • Total Risk Transfer: Avoid unplanned downtime and ensure reliability with a PackageCARE Service Agreement.
  • Intelligent Uptime: Integrated with Helix™ Connected Platform, a state-of-the-art system that gives you real-time insights and data to keep your compressor operating at peak performance and reduce the risk of downtime.
