Advantage of Centrifugal Fan with Variable Frequency Motor by Xianrun Blower

Advantages of Centrifugal Fan with Variable Frequency Motor by Xianrun Blower:

1. Automatic control.Reduce the labour intensity, reduce the system maintenance time, improve production, reduce operating costs.

2. Control the centrifugal fan motor starting current.Conventional centrifugal fan will produce 7-8 times current of motor at the start,then generate heat, and reduce the service life; while variable frequency motor can reduce the maintenance cost, and increase service life.

3. Reduce the electric power line voltage fluctuation.Conventional motor startup will cause current surge, and voltage fluctuations, all that leads to voltage sensitive equipment failure or abnormal work; variable frequency motor because can start step by step from zero frequency zero voltage,and avoid failure.

4. Adjust centrifugal fan air volume smoothly; and make industrial fans and blowers work in the best working point; blower performance curve conforms to the system; improve the centrifugal fan efficiency; avoiding surge; stabilize the furnace pressure; meet the requirements of the work environment.

5. Low speed operation can reduce centrifugal fan blade wear, reduce noise, prolong the life of the industrial blowers and motors.

6. Good energy saving effect. Due to the air flow is in direct proportion ratio to the square of rotational speed, and power consumption is in direct proportion ratio to the cube of rotational speed, the centrifugal fan with variable frequency motor is more energy efficient.
