The AC Infinity CLOUDLINE PRO S is a mixed-flow inline duct fan system designed for quiet, energy-efficient ventilation in grow rooms, grow tents, AV equipment closets, bathrooms, attics, and a broad range of HVAC and air exchange applications. Powered by a PWM-controlled EC motor with a stator blade and dual hydrodynamic wind circles, it maintains strong airflow even in high static pressure environments, such as those encountered when running through a carbon filter, long duct runs, or multiple bends, without the noise or energy consumption of conventional AC motor fans.
The included wired 10-speed controller provides straightforward manual airflow adjustment from the control unit, letting growers dial in the exact output level needed for their space without complex programming. While the S Series does not include the temperature, humidity, and VPD programming of the T Series, the fan is fully UIS compatible and connects to any AC Infinity UIS controller, including the Controller 69 Pro, to access intelligent climate-based programming, grow cycles, scheduling, and app control without replacing the fan unit. The detachable motor box removes from the mounting flange for periodic cleaning without disassembling the full installation.
Dual ball bearings rated to a 67,000-hour L10 life expectancy and an IP44 rating for dust and liquid resistance make the CLOUDLINE PRO S a reliable long-term performer in demanding growing environments. The fan mounts and operates in any orientation, horizontal, vertical, or angled, for maximum installation flexibility. For a grower who wants a dependable, quiet inline fan at a lower entry point and plans to integrate a UIS controller later, the CLOUDLINE PRO S provides a future-ready foundation without compromise.

Determine your installation method, the CLOUDLINE PRO S can be wall or ceiling mounted, or hung vertically from tent poles or overhead supports. Wall or ceiling mounting: remove the motor box from the flange by unscrewing the metal rings. Use the flange bracket as a template to mark four mounting holes on the surface. Drill and insert wall anchors if mounting to drywall or masonry, then secure the bracket using the included machine or wood screws. Hanging: thread the included hanging straps through the fan's mounting points and loop around a suitable overhead support. Clip the carabiners together and adjust the strap length to achieve the desired height and angle.
Reattach the motor box to the mounted flange, confirming the airflow direction arrow points correctly, toward the exhaust point for extraction, or toward the grow space for intake.
Connect the fan's power cord directly to a standard power outlet.
Plug the wired speed controller into the fan's controller port and set the desired airflow level from 1 (lowest) to 10 (highest).
To connect to a UIS controller for intelligent climate programming, grow cycles, scheduling, and app control, plug the fan into a UIS controller port using the included UIS adapter.
Periodically remove the motor box from the mounting flange and clean the impeller, fan blades, stator blades, and wind circles with a damp cloth.
