Featuring an energy-efficient EC motor with PWM speed control, it delivers up to 807 CFM airflow at whisper-quiet 39 dBA noise levels. Its mixed-flow design and dual ball bearings ensure high static pressure and durability, while IP44 rating protects against dust and moisture. Ideal for hydroponics, grow tents, AV cooling, and HVAC boosting, it includes a full installation kit and integrates with smart controllers for customizable climate management. ## Description Inline Duct FanA smart inline duct fan designed to quietly ventilate hydroponic grow rooms, boost heating/cooling to rooms exhaust projects, and cool AV closets. Features an inline speed controller utilizing PWM-technology. Contains a mixed-flow design and an 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, necessary mounting hardware, and a corded power adapter (UK 3-pin 220-240V AC Wall Plug - Type G).Precise Speed Controller 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.Quiet and Energy Efficient DesignThe 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. Review: Good quality. Very quiet. - Good quality. Very quiet. Using for 1.5 years.
