The CD14D1 is a single-stage, gear-driven, oil-free screw air end manufactured by Ingersoll Rand (through its GHH-RAND subsidiary). It is part of the CD series of dry-running compressor blocks designed for applications requiring 100% oil-free compressed air. The CD14D1 is engineered for continuous operation in demanding industrial environments and is commonly integrated into compressor packages for low to medium pressure applications.-
Typical Technical Parameters:-
Flow Rate: 750–1,790 m³/h (approx. 441–1,053 CFM)
Discharge Pressure: 4.5~11.5 bar
Power Range: 58.3~221.4kW
Weight: 530 kg
Dimensions: 760 × 730 × 770 mm
Ultracoat Coating – Boosts efficiency, lowers discharge temperature, increases flow, reduces power consumption, and provides corrosion protection up to 270°C.
Single-Stage Compression – Simple, reliable design for low-pressure applications up to 4.6 bar.
Gear-Driven Package – Compact unit with integrated gearbox, oil tank, pump, and filter.
100% Oil-Free – Dry-running design eliminates contamination risk for sensitive industries.
High Efficiency – Optimized rotors and Ultracoat coating deliver superior volumetric efficiency.
Low Maintenance – No oil separation or disposal; robust design ensures long service life.
