EC centrifugal fans offer a practical path toward direct drive, variable-speed operation and integrated control in AHU applications.
The value of EC axial fans lies in their ability to adjust speed according to heat pump load. Through 0–10V, PWM or communication-based control, fan speed can be adapted to the operating status of the unit.
The difference between AC and EC centrifugal fans is not simply a matter of motor type. AC fans represent a mature and reliable conventional solution, while EC fans place greater emphasis on operating efficiency, control flexibility, and long-term cost performance. As energy efficiency, industrial cost control, and intelligent system management become more important, fan selection is shifting from simply meeting airflow requirements to evaluating overall operating value.
