Description Cloudline T6, Quiet Inline Duct Fan System Controller 69 Pro, 6 Inch - 150mm This item ships with the Controller 69 Pro with Wifi and Bluetooth • Designed to ventilate hydroponic grow rooms, transfer heating/cooling, cool AV closets, and exhaust odours. • Dynamic temperature and humidity programming, with timers, grow cycles, scheduling, minimum speed. • Remotely connect to our WiFi app to access advance programs, view climate data, and set automation. • Mixed flow design combined with a PWM-controlled EC-motor for a truly quiet and energy efficient performance. • Duct Size: 6” | Dimensions: 7.9 x 12.6 x 8.4 in. | Airflow: 402 CFM | Noise: 32 dBA | Bearings: Dual Ball 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. SMART CONTROLLER CONTROLLER 69 PRO features smart programming that not only has basic temperature, humidity, and VPD triggers but also allows you to set dynamic fan speeds that would respond based on their changes. Go even further by setting a minimum speed that the fan will run at constantly and would only increase when triggered. Timer, cycle, and schedule modes add custom on-demand activation for various uses. Securely connect to the AC Infinity app via WiFi to utilize automation capabilities from anywhere throughout the day. Access your fan remotely, unlock advance programs, set notifications, view historical climate charts, and export CSV data. This controller can connect to up to four UIS devices which includes products like the CLOUDLINE, CLOUDRAY, and IONFRAME Series. It can also connect to your favorite grow light and outlet device from outside the UIS platform using select adapters. QUIET AND ENERGY EFFICIENT DESIGN Unlike common duct fans that use an AC motor which is loud and unmanageable, this duct fan features an EC motor that is controlled using PWM (Pulse Width Modulation). This technology enables motors 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 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 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. How to use the Controller 69 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.
