This fan is characterized by its external rotor motor, which is mounted on the outside of the fan wheel. The external rotor configuration allows for a compact and integrated design, making it suitable for applications with limited space, such as compact HVAC units and ventilation systems. The forward-curved blades help achieve a high airflow volume and maintain quiet operation. The external rotor design also improves the efficiency of the fan, reducing energy consumption. These fans are often used in residential, commercial, and industrial applications, where reliability and compactness are crucial.
