The CD26S is an Ingersoll Rand, ultra-large-displacement, high-performance, dry-type, oil-free screw airend. As the core power unit of large oil-free screw compressors, it generates large volumes of pure compressed air through the high-speed rotation of two rotors in an oil-free environment. It is designed specifically to meet the centralized air supply needs of large industrial facilities.


Product features


  • Absolutely Oil-Free

    The compression chamber is completely isolated from the lubrication system, and the output air meets the strictest ISO 8573-1 Class 0 oil-free standard, eliminating the risk of oil contamination.

  • Efficient and Energy-Saving

    The advanced rotor profile design ensures a perfectly matched internal compression ratio at the target operating pressure (typically optimized around 7-8 bar), resulting in high operating efficiency and significant energy savings.

  • Reliable and Durable

      High-precision gears ensure contactless rotor transmission, and high-quality bearings and a robust body                  ensure a long design life, suitable for 24/7 continuous heavy-duty operation.

  • Large-Displacement Design

       This larger model provides greater volumetric flow (displacement capacity), meeting the gas needs of medium         and large industrial users.

Application 


The CD26S is primarily designed for large-scale industrial applications requiring large-scale, continuous, high-quality compressed air:

  • Large petrochemical/chemical plants: Providing power for process control, instrument purging, and material handling throughout the plant.

  • Mega-scale electronics/semiconductor factories: Meeting the demands of chip manufacturing, panel production, and other processes requiring extreme air volume and purity.

  • Large food and beverage groups: Suitable for central kitchens, automated filling lines, and packaging lines.

  • Pharmaceutical plants: Ensuring GMP-compliant large-scale pharmaceutical production, packaging, and cleanroom air supply.

  • Automotive OEMs: Providing clean air for entire paint shops and assembly lines.
