THROUGH THE Cultivator's LENS Highlights

  • You are moving air through long duct runs because the high static pressure keeps airflow strong.
  • You are exhausting odorous air because the mixed flow impeller moves 1604 CFM through 12 inch ducting.

  • The 10 speed controller uses a single button with a circular readout and remembers its last setting after a power outage.
  • Dual ball bearings are rated for 67,000 hours and allow horizontal or vertical mounting.

  • Growers running large spaces say the high CFM keeps heat and humidity completely under control.
  • Users managing big carbon filters say airflow stays strong without stalling out.

AC Infinity Cloudline S12 Inline Fan System w/ Speed Controller - 12" Duct

Large grow rooms, commercial tents and big workshops need serious air exchange to keep heat, humidity and odor in check, and smaller fans stall once a big carbon filter goes on. The AC Infinity Cloudline S12 moves 1604 CFM through 12" ducting with 818 Pa of static pressure, keeping airflow strong through filters, silencers and long duct runs.

A PWM-controlled EC motor drives a mixed-flow impeller with stator blades and hydrodynamic wind circles, delivering efficient airflow with minimal heat even in high-resistance setups. Use it to exhaust stale, odorous air, bring fresh air into a grow space, move heated or cooled air between rooms, or cool AV closets. Dual ball bearings rated for 67,000 hours allow horizontal or vertical mounting. The IP44-rated housing resists dust and moisture, and the motor box detaches from the mounting frame for cleaning.

The included speed controller sets fan speed from 1 to 10 with a single button and remembers its last setting after a power outage. It's powered by the fan through the included 10 ft UIS cord. For climate- and schedule-based automation, connect the S12 to any UIS controller, such as the Controller 69 Pro (sold separately), and integrate it with the rest of your AC Infinity equipment.

Frequently Asked Questions

What's the difference between the Cloudline S-series and T-series? +

The fan unit is the same; the controller is the difference. The Cloudline S12 includes a 10-speed controller for manual speed setting, while the Cloudline T12 ships with a smart controller and sensor probe that automate fan speed by temperature, humidity, timers and schedules.

How loud is this fan? +

The Cloudline S12 is rated at 62 dBA at full speed. Its PWM-controlled EC motor runs considerably quieter at lower settings, so many growers run it below maximum and step up only when conditions demand. Adding a 12" duct silencer to the run can reduce noise further.

How does the speed controller work? +

Each press of the single button raises the speed one level from 0 to 10, and pressing it at 10 cycles back to 0. Hold the button for 4 seconds to turn the fan off; press it again to resume at the last speed. The controller draws power from the fan through the included UIS cord.

Can I use this fan for applications other than grow tents? +

Yes. The Cloudline S12 also works for moving heated or cooled air between rooms, bringing fresh air into large spaces, ventilating basements and workshops, and cooling AV closets and equipment rooms.

Can I use the Cloudline S12 for intake and exhaust? +

Yes. Mount it with the airflow arrow pointing toward your grow space for intake, or away from it for exhaust. The mixed-flow design keeps airflow strong in either role, even with a large carbon filter attached.

What do I need to complete my ventilation setup? +

The kit includes the fan, speed controller, duct clamps, hanging straps and mounting hardware. You'll need 12" ducting, such as AC Infinity 12" Flexible Ducting, plus a 12" carbon filter if you need odor control. For setup tips, see our guide on setting up AC Infinity ventilation kits.

Can I control this fan with my smartphone? +

Not with the included speed controller. Connect the S12 to a UIS controller such as the Controller 69 Pro to unlock app control, automation and scheduling. Note that EC-motor fans like the S12 cannot be daisy-chained with DC-motor models.
