Features of permanent magnet variable frequency air compressors

1. Ultra-low temperature lift design, compressor allows for stable operation of low frequency

2. Adopt closed-loop vector control system, PID adjustment is more accurate and stable

3. When the operating frequency is above 50%, the overall compressor system still maintains high volumetric efficiency

4. Stable startup, gentle acceleration, avoid current peak impact, and the power grid is protected from impact and overload startup

5. Precise voltage regulation, achieve target pressure fluctuation within 0.01MPa, reduce unnecessary energy loss. Pressure increases 0.1MPa, the electricity consumption rises by 6%.
