Asynchronous two-stage screw air compressors of the DD series include the following models: DD-30, DD-40, DD-50, DD-60, DD-75, DD-100, DD-125, DD-150, DD-175, DD-220, DD-250, DD-275, DD-300, DD-350, DD-375, DD-375W, DD-420, DD-420W, DD-475, DD-475W. Features: ✅ Air supply range from 2.55 to 73 m3/min. ✅ Power from 22 to 355 kW. ✅ Working pressure from 0.7 to 1.3 MPa. ✅ Efficient two-stage compression unit. The rotor has a patented profile that ensures rotor profile accuracy, high reliability and availability, low noise and vibration. Two-stage compression reduces the single-stage compression ratio and bearing load, which increases the service life of the compression unit. ✅ High-efficiency asynchronous motor. Special air-cooled motor, the specific input power of the whole machine is lower, which effectively prevents dust and moisture from entering the motor, SKF bearings ensure long-term smooth operation. ✅ Class 1 energy efficiency.
