The EC cross‑flow / tangential fan adopts an integrated structure of permanent‑magnet direct‑drive motor and long‑casing impeller. Different from the air supply mode of conventional fans, air flows horizontally through the impeller to deliver even air output, stable airflow field and well‑organized long and narrow air duct.
Eliminating belt‑driven structure, the fan causes no mechanical transmission loss. It supports 0‑100% stepless intelligent speed regulation to precisely adjust wind speed and air volume according to environmental load.
Built‑in intelligent drive system is equipped with multiple safety protections against over‑current, over‑temperature and locked‑rotor. It supports 0‑10V and PWM signals to connect with automatic control system for intelligent regulation and self‑diagnosis of faults.
Compact in overall size, the unit features low‑vibration and low‑noise operation. Without vulnerable spare parts, it can run stably 24‑hours long‑term with no routine maintenance required.
Suitable for narrow‑long spaces and flat‑surface uniform air‑supply scenarios, it is widely applied in commercial equipment, building ventilation and air‑conditioning supporting systems, serving as an ideal option for energy‑saving upgrade of traditional tangential fans.
