PM VFD screw air compressor with only 0.8 mpa pressure

The permanent magnet frequency conversion single-stage screw air compressor is a high-efficiency, low-noise, and reliable compression solution driven by advanced permanent magnet synchronous motor and frequency conversion technology. Widely recognized in the market, this compressor delivers outstanding energy efficiency and stable performance in diverse industrial environments.

Features of PM VFD Screw Air Compressor

1. Permanent Magnet Synchronous Motor (IPM): Core driving component with no slip and no electric excitation, using UH grade magnets to ensure stable operation in harsh environments and avoid demagnetization. Greatly reduces energy loss and boosts overall energy efficiency compared to traditional motors.
2. Frequency Conversion Drive System: Advanced inverter technology enables real-time speed adjustment from 0–100%, allowing high-efficiency operation across varying loads, reducing energy waste, and minimizing mechanical wear.
3. Screw Compression Technology: High-quality screw tooth design and small clearance ensure superior compression efficiency, higher output, and longer operational life. Optimized screw structure delivers stable air output under all load conditions.
4. High-Efficiency Transmission System: Embedded one-piece shaft direct connection between motor and screw rotor eliminates gearboxes and belts, achieving 100% transmission efficiency, reducing energy loss, and making the equipment more durable and easy to maintain.
5. Air Volume and Pressure: Provides 3.5 m³/min air volume at 0.8 MPa, meeting most industrial air requirements and ensuring stable, high-pressure output.
6. Environmental Adaptability: High-quality magnetic steel construction maintains excellent performance in high temperature and high humidity, preventing demagnetization and ensuring long-term stable operation.

Working Principle

1. Screw Compression: Air is drawn in and compressed by the screw rotor, with optimized tooth design minimizing loss and maximizing efficiency.
2. Frequency Conversion Speed Regulation: Motor speed is automatically adjusted in real time based on load, achieving high-efficiency, energy-saving performance through precise regulation.
3. Permanent Magnet Motor Drive: IPM motor uses permanent magnets to generate a stable magnetic field, avoiding inefficiencies and energy loss found in traditional motors, and ensuring consistent, long-term operation.
