Panrui PRVF permanent-magnet variable-speed single-stage rotary screw air compressor delivers stable, energy-efficient compressed air for continuous industrial use. Available in air-cooled and oil-cooled versions, 7.5–37 kW (10–50 HP), with GB19153 Grade-1 energy efficiency.
PRVF Single-Stage Advantages
- Permanent-magnet rare-earth motor saves 25–35% energy versus standard fixed-speed units.
- Coaxial direct-drive design reduces mechanical loss and raises transmission efficiency.
- Hard-pipe connection, 12-hour factory run test and enlarged air paths prevent leakage.
- Three-in-one vibration damping lowers noise by 30%; rated 66–78 dB.
- High-precision multi-layer oil separator keeps oil carry-over at or below 3 ppm.
- Designed for 52°C ambient operation, well above the industry 40°C standard.
