variable frequency screw air compressor for chemical

The permanent magnet variable frequency single-stage screw air compressor is an energy-efficient and stable solution, widely used in industrial settings where high-quality compressed air is essential. Thanks to advanced variable frequency control technology and a high-efficiency permanent magnet motor, this compressor provides improved performance, environmental benefits, and a long service life. It is ideal for applications requiring precise adjustment of compressed air output.

Features of Variable Frequency Screw Air Compressor

1. Frequency conversion host: Utilizes a frequency conversion drive screw host with finely optimized screw tooth shape, ensuring excellent screw linear speed and compression efficiency. Maintains constant efficiency from 0 to 100% load for high efficiency under all conditions.
2. High-efficiency permanent magnet motor: No slip or electric excitation, no base wave iron/copper loss, and uses UH-grade magnetic steel for stable, efficient power output without demagnetization in harsh environments.
3. No transmission efficiency loss: Embedded one-piece shaft direct connection between motor and screw rotor eliminates gearboxes and belts, achieving 100% transmission efficiency and reducing energy loss.
4. Precise speed regulation & energy saving: Advanced vector heavy-duty motor and rare earth permanent magnet frequency technology enable smooth, stepless speed adjustment from 0–100%, keeping the compressor running precisely and energy-efficiently under constant pressure control.
5. Air volume and pressure: Delivers 12.6 m³/min airflow at up to 0.8MPa, meeting the stable air supply needs for most industrial applications and ensuring reliable, continuous operation.

Working Principle

The compressor operates via screw compression and variable frequency speed control. Air is compressed by the rotating screw rotor, while an inverter control system adjusts motor speed to match air demand, stabilizing output pressure and airflow. Permanent magnet motors offer high efficiency, minimize heat and mechanical loss, and optimize overall system performance.
