This fan is composed of an external rotor asynchronous motor, plastic impeller, and other components. It has the unique advantages of ventilation, heat dissipation, and self-cooling, with low motor temperature rise, thus extending the fan's life and reliability.
This fan features a backward-curved impeller, which has characteristics of compact structure, large airflow, high static pressure, low vibration, low noise, and easy installation. It is mainly used in clean workbenches, clean units, indoor duct dust removal, clean air conditioning systems, environmental protection, pollution control, and other refrigeration equipment.
