Motor F-class insulation+VPI vacuum impregnation, resistant to condensation water and high humidity.
Double ball bearings have a lifespan of 40000 hours and are compatible with heat pumps, with a design lifespan of 10-15 years.
Q: What are the advantages compared to AC centrifugal fans?
Under the same static pressure, the overall efficiency of the EC centrifugal fan is 20-30% higher; The speed range is 0-100% infinitely adjustable, and AC centrifugal fans can only use external speed controllers for gear shifting or voltage reduction speed regulation; EC has built-in MODBUS communication, and operational data can be transmitted back. The investment payback period is approximately 2 years in a data center scenario of 8760 hours per year.
Q: How much control accuracy can be achieved?
The EC centrifugal fan adopts closed-loop PID speed regulation, with air volume control accuracy of ± 3% and speed control accuracy of ± 1%. Sine Wave Drive has lower noise and smaller torque ripple compared to square wave drive, which is crucial for vibration-sensitive scenarios such as medical ventilators and MRI cooling.
