PRODUCT DESCRIPTION

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 UIS™ platform of grow devices and smart controllers, designed to integrate with each other to achieve your ideal environment.

PRECISE SPEED CONTROLLER

The speed controller enables you to set the duct fan’s speed between ten speed levels to optimal noise and airflow levels in various environments. The precise airflow control is supported by the inline fan’s cutting-edge EC motor that is precisely controlled using PWM (Pulse Width Modulation). This enables it to run smoothly at extremely low RPM speeds without generating motor noise. Also features backup memory that retains the last speed setting whenever power is cut off from the controller.

QUIET AND ENERGY EFFICIENT DESIGN

This duct fan uses a mixed-flow design using a stator blade and dual hydrodynamic wind circles, enabling it to deliver airflow even in applications where air movement is restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be highly resistant to dust and liquids and performs well even in harsh environments.

APPLICATIONS

This quiet duct fan system is popular in a variety of applications including cooling AV equipment rooms, closets, racks, and cabinets. Due to its low noise and advanced control features, it’s also used in various air circulation and ventilation projects including hydroponic grow rooms and tents, exhausting bathrooms and attics, and other installations.
