Panrui PRCF permanent-magnet variable-speed two-stage (horizontal) rotary screw air compressor, 11–75 kW (15–100 HP). Two-stage compression with permanent-magnet motor exceeds GB19153 Grade-1 efficiency limits.
Two-Stage Advantages
- Stable non-stop operation with high-precision rotor meshing and self-developed VSD control.
- Saves 11–16% energy versus single-stage; 20–50% energy-saving potential.
- Hard-pipe connection and dual leak tests prevent air and oil leakage.
- Precision rotor balancing, damping base and multi-layer insulation keep noise low (68–75 dB).
- Three-stage oil separation for clean compressed air.
- Air end and VSD drive each carry a 2-year warranty.
