CLOUDLINE Series

An inline duct fan designed to quietly ventilate grow tents, boost heating/cooling to rooms, circulate fresh air, exhaust projects, and cool AV closets.

A Quieter and Smarter Inline Fan

The new CLOUDLINE series contains a cutting-edge Electronically Commutated (EC) motor, controlled using precise electronic pulses and smart programming. This enables the inline fan to operate considerably quieter, and reach low speeds without generating noise or heat. The EC motor is also twice as energy efficient and can save up to 40% in energy costs, paying for itself in the long run.


Smart Programming T-series models include a programmable controller with precise temperature and humidity sensors located on the 12-foot corded probe.	Quiet PWM Motor Each fan uses a quiet, energy-efficient EC motor controlled using Pulse Width Modulation (PWM). Dual ball bearings allow for omnidirectional mounting.	Mixed-Flow Design Featuring a mixed flow design, the fans maintain peak performance in high static pressure environments. Ingress-protected against dust and liquids.	Plug and Play The complete kit includes the inline fan unit, controller, user manual, and everything needed to mount the fan and power it through an outlet.


CLOUDLINE 4-Series A CLOUDLINE T4 plus CLOUDLINE S4 system can be linked to the same smart controller, and used in conjunction for a total of 410 CFM airflow. This set-up is ideal for ventilating smaller grow tents and cooling AV rack cabinets.	CLOUDLINE 6-Series A CLOUDLINE T6 plus CLOUDLINE S6 system can be linked to the same smart controller, and used in conjunction for a total of 804 CFM airflow. This set-up is ideal for large grow tents, AV closet cooling, and boosting airflow for HVAC projects.	MIX and MATCH The same controller can connect CLOUDLINE fans of different sizes, to share the same programming. For example, an exhausting CLOUDLINE T6 with a filter can share the same controller as an intaking CLOUDLINE S4, to balance static pressure.

Product description

Inline Duct Fan

The duct fan system is designed to quietly cool AV equipment rooms and closets, and to ventilate various air circulation and exhaust projects. Features an inline speed controller utilizing PWM-technology. Contains a mixed-flow design and an EC-motor for a quiet and high static-pressure performance. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Complete kit includes one duct fan unit, one inline speed controller, installation manual, and all necessary mounting hardware.

Precise Speed Controller

The inline speed controller enables you to set the duct fan’s speed to optimal noise and airflow levels for various environments. Unlike common AC-powered duct fans that suppresses voltage to control fan speeds, this duct fan features an EC-motor that is precisely controlled using PWM (Pulse Width Modulation). This technology enables the fan's motor to be able to run smoothly at extremely low RPM speeds without generating motor noises and heat as seen on variable voltage controllers. Eight-speed options are available with a power switch, and backup memory. This S6 model can be connected to the smart controller of the CLOUDLINE T6 (AI-CLT6) model to share the same programming and power source.

Quiet and Energy Efficient Design

The inline booster fan features 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 being 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.

Energy efficient.

Reviewed in the United States on November 26, 2018

Verified Purchase

Measured 7 watts on low setting and 37 watts on high setting. All eight settings are distinct and work. Absolutely quiet. Mounting was a breeze. Great value. I’ve had many in-line exhaust fans and this is the best by far. Uses 1/5 the watts for the same air movement as my centrifugal fan.
Absolutely one of the highest quality products I’ve bought in my life of 64 years.
I’m rating this shortly after installation. Judging from the quality, I expect this unit to last. I will change my rating if it does not.

[UPDATED] Nice and quiet

Reviewed in the United States on February 10, 2019

Verified Purchase

I own two of these fans. One is used for room exhaust, pumping air out of the lung room and drawing fresh air in as a result. The other provides ventilation for a small grow tent. It is actually overpowered on max speed, but dialed down to an appropriate speed. I love the idea that I can re-use the fan if I ever decide to move to a larger tent.

Both fans are very quiet, and the speed controls allow me some degree of control over temps and humidity to get as close as it is possible to get to the proper VPD value in my situation.

Overall, with the exception of a bit of a rocky start, I am quite pleased with these fans.

Not just for growers. Quiet, convenient, just what I needed.

Reviewed in the United States on February 12, 2019

Verified Purchase

I actually use this fan because my south-corner room full of aquariums has no ventilation, and the windows don't allow for good air circulation. This makes my room unbearable for sleeping and my nose gets stuffy.

Coincidentally, the styrofoam supports that the fan come with fit perfectly together to form a seal in my window.
After fitting a duct-collar through one of the styrofoam blocks and setting up the ducting, my room doesn't smell, my nose isn't stuffy, and it's way more comfortable in my room.

Now im considering buying another for use as an intake. It comes with a 10-speed controller, which has an extra long cord, and I'm surprised at how quiet the lower speeds are. After halfway to max speed, it gets noisy.

After months of researching whether it was worth spending the $120 for this project to make my room comfortable, I can easily say I am happy I did this and love this fan and what it has done for my room.

installation

Reviewed in the United States on September 16, 2018

Verified Purchase

Regarding the design of the fan and controller. It would be better to change the design for the fan mounting to allow installation without disassembly. It is tedious to have to manage the clamps, little screws and nuts and the clamp alignment when installing in tight places. Especially in crawl spaces where space is confined. dropping one of the screws/nuts and/or aligning the clamps makes the install a challenge. I also see that a longer controller cord is beneficial, as the existing length barely allows the controller to be installed at normal switch level when the fan itself is installed in the ceiling/crawl space. with respect to the controller, the screw location for mounting would be better if it conformed to the dimensions of a standard wall box. Furthermore, the location of the connectors severely limits the cosmetic finishing options for install in areas like a kitchen or bath. This would require dimensional changes as well as connection orientation. Simple fixes that would expand the utility of the fan/controller and inevitably increase sales.

Good fan, quiet and strong enough for a 4x4 for sure

Reviewed in the United States on December 20, 2018

Verified Purchase

Good fan, using it in my 4x4 tent with a carbon filter hooked up to it. The tent has to be in my living room so I opted in a quiet fan. This one is just as loud as all the fans on my lights already, near silent at half speed, at full speed just sounds like you have a fan on. I would recommend for quiet operations but if you need SILENT then you probably aren't gonna find any fan since the movement of air causes a good amount of noise.

Solid

Reviewed in the United States on September 27, 2018

Verified Purchase

Great quality and low noise/high air volume (variable) fan. The only downside is, the fan blades are kind of tight and that impedes air flow when the fan is off. So the already weak vent is even weaker unless the fan is turned on. This is actually good for me because the room I’m using it for is an office that doesn’t need to be cooled unless I’m in it. If you want this to boost a call Mom area, I’d recommend getting the one with the thermostat and controller. I also read a review of a guy wiring a relay to turn this on when his a/c turned on. It’s possible but above my skill level.

Was the best fan I ever had (for about a year)

Reviewed in the United States on September 6, 2020

Verified Purchase

This fan is marvelous, I thought I was going to regret spending such an obscene amount on a fan but I went for it because of the good reputation.
Got two, one of them has been running almost continuously and is still perfect and (mostly) quiet.
HOWEVER the second one worked marvelously for months and months, probably about a year, but now it is making this super annoying clicking/rattling sound almost continuously now.
I've disassembled multiple times, cleaned it, and verified the blades aren't hitting anything. Ended up discovering that it is the fan motor itself which is making the rattling noise. It is coming from INSIDE the motor assembly. No way to open it up or anything as far as I can tell.
So naturally I'd have to buy a new hundred-dollar fan instead of just getting the two-dollar bearing
Guess I'm stuck with this fan. It can sure push air, but the fact that it developed to sound like a rattlesnake is a very annoying feature. I've bought countless crummy $20 fans and I don't remember them doing that. Also many computer case fans and I don't remember any of them doing that either.
Sadly I don't think I'll be buying AC Infinity again.

Awesome - Quiet and Powerful. Great purchase!

Reviewed in Canada on November 7, 2019

Verified Purchase

Awesome fan. Seriously much quieter than some of the other fans I've heard. I have the S6 Model so I can't speak for the temperature/humidity control. According to the manufacturer, the CFM's are divided equally throughout each speed setting. (44 CFM / speed).
Speed #1 - 44 CFM
Speed #2 - 88 CFM
Speed #3 - 132 CFM... etc.

It's been funning 24/7 for about 1 week now and so far so good. Quiet, powerful, easy to install - overall this is an awesome fan. You can't go wrong with this unit... ....unless you needed more than 360 CFM, in which case I would recommend their 8" unit. Cloudline fans are awesome.

High Air Movement for Low Power Usage

Reviewed in Canada on May 30, 2019

Verified Purchase

Uses shockingly low amounts of power considering it moves a whole lot of air... even at lowest settings. Very impressive. Hooked it up to smartplug that I can turn off and on from my phone app. Use it to move a large amount of air from one room and floor of my home to another. DIY duct I installed basically blows my hair back from a dozen feet away. Smartplug shows how much electricity it uses and it literally uses only a few pennies a day - basically nothing.

Great fan with 8 speeds

Reviewed in Canada on September 23, 2019

Verified Purchase

I wanted to make my own air purifier, and used this duct fan as the main piece. I'd had it for about a month and it's been great.

Pros:
The 8 speeds allows me to control the suction power and therefore the noise level.
The middle piece can be removed for cleaning.
The power has a memory so if you turned it off at speed 5, then it'll start up on speed setting 5.
I also like how the motor gradually speeds up when you turn up the speed.

Cons:
There's only one button to power on/off/cycle speeds.
With one button, the speed control is a cycle. So if you turn it up to 5, and want to turn it down to 2 then you have to go up to 8 just to cycle back to 1.

Still, I would recommend this fan.
