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. Features an inline speed controller utilizing PWM-technology. Contains a mixed-flow design and EC-motor for a quiet and high static-pressure performance. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Complete kit includes one duct fan unit, one corded speed controller, installation manual, and all necessary mounting hardware. 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.

The inline speed controller enables you to set the duct fan’s speed to optimal noise and airflow levels for various environments. Unlike common AC-powered duct fans that suppresses voltage to control fan speeds, this duct fan features an EC-motor that is precisely controlled using PWM (Pulse Width Modulation). This technology enables the fan’s motor to be able to run smoothly at extremely low RPM speeds without generating motor noises and heat as seen on variable voltage controllers. Eight speed options are available with power on/off switch. Due to its backup memory capability, the fan can be triggered to run at customizable speeds when given power. This S8 model can be connected to the smart controller of the CLOUDLINE T8 to share the same programming.

The inline fan features a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, enabling it to deliver airflow even in applications where air movement is being 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.

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.
