EC centrifugal fans adopt integrated design of permanent magnet synchronous brushless motor and electronic commutation drive. Impellers are calibrated by precise dynamic balance to ensure stable air delivery. Compared with traditional AC centrifugal fans, they remove belt transmission to avoid mechanical losses. Motor efficiency exceeds 95%. It supports 0~100% stepless speed regulation and dynamically adjusts air volume and pressure according to temperature and pressure loads for remarkable energy saving.
The built-in driver with multi-protection supports signal communication, remote monitoring and fault self-checking, and can connect to building BA and environment monitoring systems. It features low vibration and noise without common faults such as belt wear or breakage, reducing maintenance workload. The standardized modular structure matches air handling units, fan boxes and fan walls. It is widely applied in clean workshops, data centers, building HVAC ventilation and energy-saving retrofit of old fans.
