High precision constant pressure control with a pressure fluctuation range within 0.01mpa.

Remove peak current during starting, avoid the power grid impact, prevent the current impact through gradual speed regulation and improve flexibility.

Prevent idling of the compressor during running and reduce invalid energy consumption. The permanent magnet motor adopts a high efficiency rare earth magnet, without loss of excitation at 180, providing a long service life and saving about 6%-7% more energy than an ordinary variable frequency motor, obtain the maximum efficiency within a wider range to make the air compressor more energy efficient.

Low-frequency starting provides a large torque and a low running current, ensuring to get a reasonable torque to drive the air compressor to run stably with the minimum temperature rise of the motor with a wide speed range.
