This backward centrifugal fan adopts external rotor brushless DC motor, impeller diameter 220mm, fan and motor integrated structure, no belt drive. Zero current start, no impact current generation, the system is more safe. The operating noise is significantly lower than the conventional fan, the efficiency is significantly higher than the conventional motor, even at low speed, the efficiency can reach more than 85%. Up to 80,000 hours bearing maintenance-free, with fault diagnosis, fault feedback interface, RS485 communication interface. It can be applied to public buildings such as hospitals. Because hospitals have obvious changes in the flow of people, such changes are different in different time periods of a day, and the demand for fresh air is also changing at all times. Install the energy-saving fresh air system of this fan, which can adjust the fresh air volume and exhaust air volume in real time according to the change of hospital human flow or the condition of indoor air quality, so as to meet the demand of fresh air of personnel and realize energy saving, which is unimaginable in the past.
