Grower Tip
- Pair it with a 150mm carbon filter on the exhaust — its 503 Pa static pressure is built for filtered lines.
- Set a minimum fan speed so your tent holds constant negative pressure, then let temperature or VPD triggers ramp it up.
- Keep the sensor probe cord away from ballast and light cords — interference can skew the controller's climate readings.
Features
Moves serious air even through carbon filters, silencers and long duct runs.
PWM-controlled EC motor runs smoothly at low speeds without extra noise or heat.
Dynamic fan speeds triggered by temperature, humidity and VPD, plus timers, cycles and schedules.

Will the Cloudline Pro T6 fit my ducting?
Yes, if you run 6-inch / 150mm ducting — that's the T6's duct size. Duct clamps are included for both ends, and the unit measures 21.2 x 32.0 x 20.0cm overall. It mounts horizontally or vertically, so it suits tents, ceilings and wall runs alike.
How loud is it?
The T6 is rated at 32 dBA. Its EC motor is PWM-controlled, which lets it run smoothly at very low speeds without the extra noise or heat of a standard AC-motor duct fan. Setting a low minimum speed keeps day-to-day running close to silent, and a 150mm silencer can cut it further.
Can it pull air through a carbon filter?
Yes — that's what the mixed-flow design is for. With a 503 Pa static pressure rating, the T6 maintains airflow in high-resistance lines, so pairing it with a 150mm carbon filter for odour control won't choke your exhaust the way it can with cheaper fans.
What does the included Controller 69 Pro actually do?
It adjusts fan speed automatically from temperature, humidity and VPD triggers, holds a constant minimum speed, and adds timer, cycle and schedule modes. Over WiFi, the AC Infinity app unlocks remote access, alerts, climate history and CSV export. It also runs up to four UIS devices, like Cloudray fans or Ionframe lights.
How much power does it use?
The T6 averages 38 W in normal use with a maximum draw of 70 W, running on a standard Australian three-prong plug at 100–240 V. Because the controller only ramps the fan up when your triggers demand it, most grows keep it near the low end of that range.

Product Description
A smart inline duct fan designed to quietly ventilate hydroponic grow rooms, boost heating/cooling to rooms, circulate fresh air, exhaust projects, and cool AV closets. Featuring an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. It is built with a PWM-controlled EC motor for quiet and energy-efficient performance. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Includes a smart controller with dynamic climate and time-based programming and can connect to multiple UIS devices. This product is a part of the UIS™ platform of grow devices and smart controllers, designed to integrate with each other to achieve your ideal environment.
Smart Controller
CONTROLLER 69 PRO features smart programming that not only has basic temperature, humidity, and VPD triggers but also allows you to set dynamic fan speeds that would respond based on their changes. Go even further by setting a minimum speed that the fan will run at constantly and would only increase when triggered. Timer, cycle, and schedule modes add custom on-demand activation for various uses. Securely connect to the AC Infinity app via WiFi to utilize automation capabilities from anywhere throughout the day. Access your fan remotely, unlock advance programs, set notifications, view historical climate charts, and export CSV data. This controller can connect to up to four UIS devices which includes products like the CLOUDLINE, CLOUDRAY, and IONFRAME Series. It can also connect to your favourite grow light and outlet device from outside the UIS platform using select adapters.
Quiet and Energy Efficient Design
Unlike common duct fans that use an AC motor which is loud and unmanageable, this duct fan features an EC motor that is controlled using PWM (Pulse Width Modulation). This technology enables motors to be able to run smoothly at extremely low RPM speeds without generating additional heat or noise. In addition, the duct fan uses a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, enabling it to deliver airflow even in applications where air movement is restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be highly resistant to dust and liquids and performs well even in harsh environments.
Applications
This quiet duct fan system is popular in a variety of applications including cooling AV equipment rooms, closets, racks, and cabinets. Due to its low noise and advanced control features, it’s also used in various air circulation and ventilation projects including hydroponic grow rooms and tents, exhausting bathrooms and attics, and other installations.
