Product features

1. Significant energy-saving effect: The permanent magnet synchronous motor can save 30% or even more energy compared to ordinary industrial frequency air compressors.

2. Stable and reliable operation. The permanent magnet synchronous motor has high overload capacity and anti-interference ability. It can operate stably under various working 

conditions and is not prone to overheating, stalling and other problems, providing reliable guarantee for the long-term stable operation of the equipment.

3. Low motor noise: The permanent magnet synchronous motor itself has the characteristics of low noise, and the electromagnetic noise and mechanical noise generated during 

operation are small.

4. Low maintenance cost, optimized structural design, small number of wearing parts, reliable quality, long replacement cycle, reducing maintenance workload and replacement cost.
