Designed to ventilate grow rooms, boost heating/cooling, circulate fresh air, exhaust projects, and cool AV closets Features a wired 10-speed fan controller; also compatible with all UIS controllers with intelligent programming. PWM-controlled EC motor provides quiet and energy-efficient performance with minimal heat and noise. Mixed flow design with stator blade and hydrodynamic wind circles enable airflow delivery in high resistance areas. A smart inline duct fan designed to quietly ventilate hydroponic grow rooms, boost heating/cooling to rooms, circulate fresh air, exhaust projects, and cool AV closets. Featuring an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. It is built with a PWM-controlled EC motor for quiet and energy-efficient performance. The motor box containing the fan's impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Includes a smart controller with dynamic climate and time-based programming and can connect to multiple UIS devices. This product is a part of the UISâ„¢ platform of grow devices and smart controllers, designed to integrate with each other to achieve your ideal environment.
