AC Infinity Cloudline Pro S4 fan description

The AC Infinity Cloudline Pro S4 fan is a smart inline duct fan designed to quietly ventilate hydroponic grow rooms, increase room heating/cooling and circulate fresh air. The inline mixed flow duct fan is capable of maintaining airflow at high static pressures. It is equipped with a PWM controlled EC motor for quiet and energy efficient performance. The motor housing containing the fan impeller and blades can be removed from the mounting frame for easy cleaning and maintenance. It includes a smart controller with dynamic climate and time-based programming and can be connected to multiple UIS devices. User's guide can be found here.

Precise speed controller
The speed controller allows you to adjust the speed of the duct fan between ten speeds for optimal noise and airflow levels in different environments. The precise airflow control is supported by the in-line fan's cutting-edge EC motor, which is precisely controlled using PWM (pulse width modulation). This allows it to operate smoothly even at extremely low speeds without generating any motor noise. It also has a backup memory that retains the last speed setting if the controller loses power.

Quiet and energy-efficient design
It uses a mixed-flow design that uses a stator vane and dual hydrodynamic wind circles, allowing it to provide airflow even in rooms where air movement is limited. The motor features dual ball bearings rated for 67,000 hours, allowing the duct fan unit to be mounted in any orientation. The unit is IP44 rated, making it highly resistant to dust and liquids, and performs well even in harsh environments.
