A 160–220kW dry oil-free rotary screw air compressor is a type of industrial air compressor that delivers 100% oil-free compressed air without injecting any liquid (oil or water) into the compression chamber .


The term "dry" means the compression chamber operates completely dry—no oil or water is used for lubrication, sealing, or cooling during the air compression process . The rotors do not contact each other; they maintain precise clearance and are driven by synchronization gears

RO-55A-4

Key Advantages

  • 100% Oil-Free Air (Class 0 Certified) – No oil in compression chamber; meets ISO 8573-1 Class 0 standards for absolute air purity

  • High Energy Efficiency – Advanced rotor profiles and precision machining reduce leakage and energy loss; up to 30% more efficient than traditional designs .

  • Variable Speed Drive (VSD) – Automatically adjusts motor speed to match air demand, saving energy during partial loads .

  • Low Maintenance – No oil filters or separators to replace; fewer wearable parts reduce downtime and operating costs .

  • Quiet Operation – Advanced noise-dampening design ensures low decibel levels, suitable for indoor installation .

  • Compact Footprint – Space-saving design (up to 50% smaller than competitors) ideal for facilities with limited floor space .

  • Durable Construction – Stainless steel rotors with anti-corrosion coatings ensure long service life even in demanding environments .

  • Heat Recovery Capable – Waste heat can be recovered for space heating or process hot water, reducing overall energy costs
