Description

Quiet Ventilation Design: Created to ventilate grow tents smoothly, transfer heating/cooling to rooms, circulate fresh air and cool down AV closets. The fan operates at a quiet noise level with energy-efficient performance minimizing heat and noise.

Wired 10-Speed Fan Controller: Compatible with all UIS controllers boasting intelligent programming. The speed controller allows you to set the duct fan's speed to the optimal noise and airflow levels in different environments. This feature is supported by the inline fan's cutting-edge EC motor controlled using PWM (Pulse Width Modulation) for smooth running at very low RPM speeds without generating motor noises.

Mixed Flow Design: Comprises of a stator blade and hydrodynamic wind circles, facilitating airflow delivery in areas with high resistance. The duct size is 4” and it offers an airflow of 205 CFM. The fan is designed with an EC motor that is PWM-controlled, providing energy-efficient performance.

Easy Maintenance: The motor box containing the fan's impeller and blades can be detached from the mounted frame, simplifying cleaning and maintenance processes. Also features backup memory that maintains the last speed setting even when power to the controller is interrupted.

Resilient and Durable: The unit is rated IP44 for high resistance to dust and liquids, ensuring it operates effectively even in challenging environments. The motor houses dual ball bearings with a life rating of 67,000 hours, allowing you to mount the duct fan unit in any direction.

Wide Application: This quiet duct fan system is frequently used in a variety of applications such as cooling AV equipment rooms, closets, racks, and cabinets. Because of its low noise and advanced control features, it's also used in different air circulation and ventilation projects including exhausting bathrooms and attics, and other installations.
