The two-stage permanent magnet VSD screw air compressor is designed for industrial users who require high efficiency, stable pressure and continuous air supply.
By using two-stage compression, the compressor reduces the compression ratio of each stage, lowers internal leakage and improves volumetric efficiency. According to Ruihong’s product specifications, the two-stage design can increase air delivery by nearly 15% and achieve approximately 15% energy savings.
The variable-speed system automatically adjusts motor speed according to actual air demand, helping reduce unnecessary power consumption when air usage changes.
The two-stage series covers power ratings from 22 kW to 250 kW, with multiple airflow and pressure configurations available.
Standard working pressures include approximately:
0.8 MPa / 1.0 MPa / 1.2 MPa
Standard electrical configuration is 380V / 50Hz / 3 Phase, with customized voltage options available.
Suitable for:
For factories with large and continuous compressed air demand, the combination of two-stage compression + permanent magnet VSD control provides an efficient and reliable compressed air solution.
