Low Pressure PM Rotary Screw Air Compressor

Low Pressure PM Rotary Screw Air Compressor

A Low Pressure PM Rotary Screw Air Compressor is engineered to deliver compressed air at pressures between 2–5.5 bar (29–80 psi), catering to applications requiring high airflow at lower pressures. Its defining feature is the integration of permanent magnet (PM) motors with variable speed drives (VSD), setting new benchmarks in energy efficiency.

Direct coupling PM motors eliminate transmission losses from belts or gears, achieving IE4/IE5 efficiency (up to 97%), cutting energy use by 30–40% compared to fixed-speed models. The VSD adjusts motor speed to match real-time demand, preventing energy waste during partial loads. Optimized rotor profiles and low rotational speeds (≤1,500 RPM) maximize airflow while minimizing power draw, with asymmetric tooth designs enhancing compression efficiency at low pressures.
