It uses a backward-curved impeller to deliver efficient airflow while keeping the motor positioned safely outside the airstream. The durable AlMg3 aluminum housing is hinged for easier servicing and includes a grease drain to support use in greasy exhaust environments. Powered by an energy-efficient IE3 motor, the unit is suitable for frequency control, allowing precise adjustment to system requirements. Designed to operate with temperatures up to 120 °C, the fan also includes an integrated device switch for added operational safety. This model provides a reliable solution for commercial kitchens requiring robust and efficient ventilation.
