Energy-Saving Backward Centrifugal Fan Blower With Belt Drive For Cooling And Ventilation Systems Industrial Centrifugal Fan

The backward centrifugal fan has significant performance advantages and unique structural features:

Efficiency and Energy Consumption:

It is a type with relatively high efficiency among centrifugal fans. The impeller blades are curved backward, so the airflow loss in the impeller is small. It can output a large air volume with relatively low energy consumption, and has obvious energy-saving effects, which is prominent in long-term operating ventilation and air-conditioning systems.

Noise Control:

The noise during operation is relatively low. Because the velocity and pressure distribution of the airflow when it flows out of the impeller is more uniform, and the airflow disturbance is small, it is suitable for places sensitive to noise, such as ventilation equipment in hospitals, office buildings, and residential areas.

Pressure and Air Volume Characteristics:

The wind pressure is relatively moderate, and the air volume adjustment range is relatively wide. When the system resistance changes, the air volume changes relatively gently, and it can maintain stable performance in a wide range of working conditions, with strong adaptability.

Structure and Maintenance:

The impeller structure is designed relatively reasonably, and the blades are not easy to accumulate dust, which is convenient for maintenance.
