后倾式离心风扇通过后倾叶片叶轮实现高效气流转换，风压稳定且抗过载能力强，能在高阻力风道中持续稳定运行，适合长距离送风需求。
Backward-inclined centrifugal fans achieve efficient airflow conversion through backward-inclined blades, with stable static pressure and strong overload resistance, enabling stable operation in high-resistance air ducts and meeting long-distance air supply needs.
相比前倾式，其运行效率更高，不易因负载变化导致电机过热，是工业通风、新风系统的理想选择，广泛应用于中央空调外机、机柜强制散热、工业除尘等场景。
More efficient than forward-inclined types, they are less prone to motor overheating due to load changes, making them ideal for industrial ventilation and fresh air systems, widely used in central AC outdoor units, cabinet cooling, industrial dust removal, etc.
