AC Infinity CLOUDLINE PRO S4 I Quiet Inline Duct Fan System with Speed Controller I 4-inch

CLOUDLINE PRO S4, QUIET INLINE DUCT FAN SYSTEM WITH SPEED CONTROLLER, 4-INCH The duct fan system is designed to quietly cool AV equipment rooms and closets, and to ventilate various air circulation and exhaust projects. Features an inline speed controller utilizing PWM-technology. Containing an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. Contains an EC-motor 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. Complete kit includes one duct fan unit, one inline 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. FEATURES Designed to quietly ventilate grow tents, transfer heating/cooling to rooms, circulate fresh air, and cool AV closets. Features an 8-speed manual controller utilizing PWM. See T-Series for temperature and humidity controls. Mixed flow design combined with a PWM-controlled EC-motor for a truly quiet and energy efficient performance. Kit also includes corded AC power adapter, installation manual, and all necessary mounting hardware. Duct Size: 4” | Dimensions: 6.9 x 11.9 x 7.4 in. | Airflow: 205 CFM | Noise: 28 dBA | Bearings: Dual Ball   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 switch, and backup memory. This S4 model can be connected to the smart controller of the CLOUDLINE T4 to share the same programming and power source. QUIET AND ENERGY-EFFICIENT DESIGN 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. 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.   SPECS    Manufacturer    AC Infinity Inc.    Product Name    CLOUDLINE S4    Product Model    AI-CLS4    UPC Code    819137020290    Product and Mounting Dimensions - Fan Unit    Duct Size    4"    Total Dimensions    7.40 x 11.93 x 6.93 in.
