<b>Inline Duct Fan</b> <p>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. Contains an EC-motor with PWM-control for a 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 an intelligent controller that features advanced programming and functions. Complete kit includes one duct fan unit, one thermal controller, one corded thermal probe, two duct clamps, installation manual, and all necessary mounting hardware.</p> <b>Intelligent Controller </b> <p>The controller can be programmed to adjust fan speeds to respond to varying high and low temperatures, and humidity. For ventilation applications, the controller can be set to run continuously or triggered to run at customizable speeds when given power, due to its backup memory capability. Additional features include a countdown timer, alarm system, and eco-mode. Includes detachable 12-foot precision probe that is water-resistant. This EC smart controller can power and control two inline fans of any size, such as this CLOUDLINE T12 with an S4.</p> <b>Quiet and Energy Efficient Design</b> <p>Features an EC-motor that is controlled using PWM (Pulse Width Modulation). This technology enables the duct fan to be able to run smoothly at extremely low RPM speeds without generating additional heat or noise. In addition, the duct fan uses a mixed-flow design for a high static pressure rating. 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.</p>
