The EC mixed‑flow fan combines the dual advantages of high air volume from axial fans and high static pressure from centrifugal fans. It adopts an integrated permanent‑magnet synchronous EC direct‑drive motor design, eliminating the conventional belt‑drive structure to avoid mechanical transmission losses.
The impeller is precisely dynamically balanced for smooth air delivery, low wind resistance and stable operation.
It supports 0~100% stepless intelligent speed regulation. Air volume and static pressure can be automatically adjusted according to duct resistance and indoor load to meet variable‑condition ventilation requirements.
Built‑in intelligent drive module provides multi‑protection against over‑voltage, over‑current, over‑temperature and rotor stall. It accepts 0‑10V and PWM control signals for integration with building BA and environmental monitoring systems, supporting remote monitoring and self‑diagnosis of faults.
Compact‑structured, easy‑to‑install, low‑noise and maintenance‑free, the unit runs stably 24/7. It is widely applied in duct ventilation, machine‑room air exchange, fresh‑air supply and exhaust scenarios, and serves as an optimal solution for energy‑saving retrofit of traditional AC mixed‑flow fans.
