5 major energy-saving advantages of permanent magnet variable frequency air compressor, do you know? Permanent magnet variable frequency air compressors have developed rapidly in recent years. Because of their high efficiency and energy saving features, they have become a hot spot and a bright spot in the industry, which has replaced the original high-energy-consuming air compressors in the market. Do you know what their energy-saving advantages are?

1. The air pressure is stable

The variable frequency screw air compressor utilizes the stepless speed regulation feature of the frequency converter. Through the controller or the PID regulator inside the frequency converter, it can start smoothly; it can quickly adjust the response when the air consumption fluctuates greatly; Compared with the power frequency, the air pressure stability coefficient is high!

2. Start without shock

Since the inverter itself contains the function of a soft starter, the maximum starting current is within 1.2 times of the rated current. Compared with the power frequency starting, which is generally more than 6 times the rated current, the starting impact is small. The important thing is that the impact force is also very small for the permanent magnet variable frequency air compressor equipment!

3. Variable flow control

The frequency conversion air compressor has a wide range of work, and the frequency converter can also be used to adjust the motor speed in real time. When the air consumption is low, the air compressor can automatically sleep, which can reduce energy waste and improve energy-saving effects.

4. The voltage adaptability of the AC power supply is better

Due to the over-modulation technology adopted by the inverter, it can still output enough torque to drive the motor when the AC power supply voltage is slightly lower; when the voltage is slightly higher, it will not cause the output voltage to the motor to be too high.

5. Low noise

Most of the working conditions of the frequency conversion system work below the rated speed, the mechanical noise and wear of the main engine are reduced, and the maintenance and service life are prolonged.
