The AC Infinity Cloudline Cloudcom T8 is the CLOUDLINE T8 smart inline duct fan, 200 mm (8″) and 1,456 m³/h · 404 L/s (857 CFM), paired with AC Infinity's new Cloudcom 6 controller in place of the Controller 69 Pro. The fan is the same CLOUDLINE T8 that has built up years of reviews on our site; the controller is the upgrade, with a 4.5″ full-colour touchscreen, six UIS ports, dual-band WiFi and optional Thread mesh for wireless devices. This is the fan we point people to for 1.5 × 1.5 m (5×5) tents and up, larger grow rooms, and big subfloor or attic runs.
The Cloudcom 6 controller
The Cloudcom 6 replaces the Controller 69 Pro that used to ship with this fan. You still get temperature, humidity and VPD triggers, minimum speed, timers, cycles and schedules, and the fan still responds proportionally, ramping up as conditions drift and easing back as they recover. What changes is how much the controller can run and how you work with it. Programming is done on a 4.5″ (11.4 cm) full-colour touchscreen, and both an onboard sensor and the 3.65 m corded probe read temperature, humidity and VPD.
Six UIS ports cover this fan plus a clip fan, a light, a humidifier and more, each on its own program, and expansion hubs (sold separately) take it to 24 wired connections. Dual-band WiFi (2.4 and 5 GHz) connects it to the AC Infinity app for remote control, alerts, climate charts and the optional AI features AC Infinity are rolling out in the app. Built-in Thread mesh can run up to 100 wireless devices through Thread mesh receivers (sold separately), and that local mesh keeps running when your WiFi drops.

Quiet, energy-efficient performance
The T8 is rated at 38 dBA at full speed, more than a T6, which is what you would expect from a fan moving twice the air. What matters more is the speed you actually run it at: a T8 at level 4 to 5 in a 5×5 is quieter and cooler than a T6 at level 9 doing the same job. Buying one size up and running it slower is the most reliable way to a quiet grow room.
Efficiency comes from the PWM-controlled EC motor, rated at 78 W average and 180 W maximum. Draw falls away steeply as you dial the speed back, because fan power scales with roughly the cube of speed. The 746 Pa static-pressure rating holds airflow up once a carbon filter, a silencer and a few metres of ducting are in the way, AC Infinity rate the dual ball bearings at 67,000 hours, and the motor box detaches so you can clean the impeller without dismantling the run.

FAQ
When will it arrive, and how do I pre-order?
Pre-orders are open now: add it to your cart and check out as normal. We estimate it will ship from Sydney from approximately 1 December 2026, subject to shipping delays. Supply of the first shipment is limited and units are allocated in order of purchase.
Is this the same fan as the T8 with the Controller 69 Pro?
Yes. The fan unit is the same CLOUDLINE T8: same motor, impeller, airflow, noise and static pressure. Only the controller in the box has changed. That is why the reviews on this page include those written for the T8 with the Controller 69 Pro; the fan they review is the fan you get.
Does the Cloudcom 6 need its own power point?
Yes. It runs from its own 12 V adapter, which plugs into a standard 240 V outlet with an Australian plug, and the fan has its own plug too. The upside is that the controller keeps running and monitoring even if a fan is unplugged or swapped, and it is not limited by one fan's power supply.
I already have a Controller AI+ or 69 Pro. Do I need this version?
Not for the fan. Any UIS controller runs it. Choose this version if you want the Cloudcom 6 itself: more ports, the touchscreen, an onboard sensor as well as the probe, and Thread mesh for wireless devices.
Do I need a T8, or will a T6 do the job?
For growing, the dividing line is tent size. A T6 handles tents up to 1.2 × 1.2 m (4×4). At 1.5 × 1.5 m (5×5) and above, 2.4 × 1.2 m (8×4), a full grow room or two tents on one extraction run, you want the T8. If your ducting and filter are all 150 mm and you would rather not replace them, the T6 is the better buy; choking an 8″ fan into 6″ ducting throws away much of its airflow.
Will it still pull properly with a carbon filter and ducting attached?
Yes, that is what the 746 Pa static-pressure rating is for. Every filter, bend and metre of flexible duct costs airflow, and a straight axial fan loses far more of its rated CFM under that load. Use 200 mm ducting and a 200 mm filter with it, keep runs short and straight, and you keep most of the rated output.
Can I use it for subfloor, attic or bathroom ventilation rather than growing?
Yes. The humidity trigger is why people choose it for those jobs: the fan runs when the space is damp and stays off when it is not, instead of running on a timer and guessing. The fan is IP44-rated and mounts horizontally or vertically. For bathroom exhaust, read the installation requirements above.
Most people use the 150 mm for a bathroom, but several customers run the T8 in a medium bathroom: it has plenty in reserve and runs very quietly at low speed. If you are unsure, send us the details and we will help.
How does the airflow compare with a ceiling or bathroom exhaust fan?
Installers rate exhaust fans in m³/h or L/s. The T8 moves up to 1,456 m³/h (404 L/s) at full speed. For comparison, the National Construction Code minimum for a bathroom or toilet is 25 L/s (90 m³/h), and 40 L/s (144 m³/h) for a kitchen or laundry, discharged outdoors rather than into the roof space. Real airflow drops with every metre of duct, bend and grille, which is where the 746 Pa static pressure rating matters. Check the requirements for your job with your installer.
Is this a genuine AC Infinity unit with Australian warranty?
Yes. Quick Bloom Lights is the official Australian importer and distributor for AC Infinity. This version ships set up for Australian 240 V power with Australian plugs, and the two-year warranty is handled here in Sydney, so there is no shipping units overseas or dealing with an offshore seller.
