AC Infinity Cloudline Pro T4 fan description

The AC Infinity Cloudline Pro T4 fan is a smart duct fan specifically designed to quietly ventilate hydroponic grow rooms, help distribute heating or cooling more efficiently, circulate fresh air, and perform exhaust duties. The fan uses a mixed-flow design that maintains optimal airflow even in high-pressure systems. Its energy-efficient and quiet operation is ensured by a PWM-controlled EC motor. The fan housing, which contains the impeller, is removable for easy maintenance and cleaning. The device comes with a smart controller that can run dynamic climate and time-based programs, and can be connected to multiple UIS devices. The product is part of the UIS™ platform, which brings together various smart devices and controllers to work together to create an ideal environment. Instructions for use can be found here. User's guide can be found here.

Intelligent controller
CONTROLLER 69 PRO is an advanced controller that not only offers basic functions - such as temperature, humidity or VPD (evaporative deficit point) based control - but also allows you to set dynamic fan speeds that react to environmental changes. You can also set a minimum speed below which the fan will never run, but can increase it if the sensors warrant it. Timing, cycle and schedule modes are also available to automatically operate the system as needed. The controller can be securely connected to the AC Infinity app via WiFi, allowing you to remotely access the fan, set complex programs, request notifications, review climate data and even export them in CSV format. The controller can manage up to four UIS devices, such as those from the CLOUDLINE, CLOUDRAY or IONFRAME series. In addition, external lighting or socket control devices can be connected using appropriate adapters.

Quiet and energy-efficient design
In contrast to traditional, noisier AC motor fans, this duct fan is powered by an EC motor with PWM technology, which allows smooth operation at low speeds without heat and noise generation. The fan's mixed-flow design with stator blades and two hydrodynamic air rings ensures high static pressure, making it effective even in systems with limited air movement. The motor’s double ball bearings can withstand up to 67,000 hours of operation and can be installed in any orientation. Its IP44 protection level means it is resistant to dust and moisture, ensuring reliable operation even in harsh environments.

Application Areas
This quiet duct fan system is popular in a wide range of applications, such as cooling rooms, cabinets, stands or racks containing AV equipment. Its low noise level and advanced control functions also make it an ideal choice for various ventilation or air circulation applications – for example in grow tents and rooms, ventilation in bathrooms or attics, and other similar installations.
