Permanent magnet variable frequency screw air compressor:
1. Constant pressure control: It can realize high-precision constant pressure control with a pressure fluctuation range of 0.01 MPa;
2. Variable frequency soft start: Eliminate the peak current when starting, avoid grid impact, avoid current impact through step-by-step speed adjustment, and improve flexibility
3. Prevent no-load: The compressor is no-load during operation, reducing ineffective energy consumption;
Permanent magnet motors use high-efficiency rare earth magnets, no loss of magnetism at 180°C, and long service life; energy saving is about 6% to 7% compared with ordinary frequency conversion motors;
It can exert the highest efficiency in a wider range and make the air compressor more energy-saving.
