AC Infinity Cloudline PRO S-Series – Quiet EC Inline Fans

The AC Infinity Cloudline PRO S-Series inline duct fans provide quiet, energy-efficient ventilation for indoor gardens, hydroponic systems and other spaces that need fresh air. A PWM-controlled EC motor and mixed-flow design help maintain airflow through ducting and other restrictive ventilation setups, while the included manual speed controller lets you balance airflow and noise.

Manual control, with room to upgrade

The S-Series includes a manual speed controller for straightforward airflow adjustment. Backup memory retains the last speed setting after a power interruption. The PWM-controlled EC motor runs smoothly at low speeds without the motor noise associated with less precise speed control.

Automatic temperature, humidity and time-based control is not included with the manual controller. For environmental automation, connect a compatible AC Infinity UIS smart controller, available separately, or choose a T-Series fan bundle with a smart controller included.

Quiet, efficient airflow

The mixed-flow design combines a stator blade with dual hydrodynamic wind circles to help maintain airflow where air movement is restricted. This makes the range suitable for ducted ventilation, including setups with carbon filters. The efficient EC motor helps keep noise and energy consumption down.

Easy maintenance and flexible mounting

The motor box, impeller and blades detach from the mounted frame for cleaning and maintenance. Dual ball bearings are rated for 67,000 hours and allow mounting in any direction. An IP44-rated enclosure provides protection against solid objects larger than 1mm and splashing water.
