AC Infinity CLOUDLINE T4, Quiet 4” Inline Duct Fan with Temperature Humidity Controller – Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics
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.
Key Features

So far works well. Really does remove smells from the tent when tent is closed! Happy with this item. It could help drop the temp a little better. But over all very happy

Great produc
Quiet, powerful, easy to setup, sensitive and responsive controls, lightweight. Very happy with this. Fast delivery. Just one tiny suggestion – if it could work via an app even better. Would highly recommend.
Simple direct installation directions. Easy to set up controls. Quiet operation.

Great piece of kit. Extremely easy to assemble and work out how to use the controller. UK plug already attached. Runs extremely silent on the first few settings. Maybe a little pricey but you get what you pay fo
Gu
Sehr guter Lfter leise auf den ersten Stufen und eine gute Anzeige schade das Mann 2 Lfter brauch um es richtig steuern zu knnen der Preis ist ok
Great for sucking hot air out of an AV cabinet into a basement. Note 4.5” holesaw makes large enough hole to pass through duct. Hold the leaf button once high temp is set to lock buttons. I set the alarms to off which I forget but is in the instructions.

This is a real deal
I’m impressed
This isn’t just a fan, it’s a quality product that performs exactly as it should, it may be early to give a review since I just received the fan less than 24 hours ago, but some products just give you that good impression once you take them out of the box.
Air movement:
The fan moves a decent amount of air with settings under 6, once you hit 7 – 10 it activates what I call “The beast mode”, it literally turns itself into a shop fan with no noticeable noise at all.
Noise level:
1-6 the noise is minimal, you may think it’s off!
7-10 noise goes up gradually, but nothing major .. could get louder with duct and based on the the surface it’s attached too, but the fan itself is super quite.
controller:
This is the best thing about the fan, the controller is smart and has many options that fits anybody’s needs, you can set a timer, high or low temp triggers, humidity triggers high and low .. it’s really amazing.
Cord length:
The fan arrives with a moderate cord length, 9 times out of 10 you won’t need an extension.
Power consumption
I didn’t test it thoroughly yet, but it averaged 20-22W, which confirms what’s stated on the label.
Things we don’t like about the fan:
1-Attaching points could be better, needs a better insulation and vibrations absorbers where the mount plate contacts the mounting surface.
2- Before I buy the fan I knew it’s overpriced, from my experience with different fans I can tell it’s slightly overpriced, should be at least 15% cheaper.
Overall I’m satisfied with this fan, and will definitely buy again.
This product was very good in reducing the temperature inside the cabinet. The noise level is very quiet. Highly recommend this product.

Best on the market, well recommended
Fantastic fan extractor, well built, lovely finished, great quality, easy to set up, very accurate humidity and temperature sensor, heavy duty cables, well packed. In the event of a power cut, the fun will automatically turn itself on once the power is back to the exact setting where it was before the power cut.
The control panel would allow you to connect and control a second fan, unfortunately, they can not be control separately. It Has 10 speed setting, incredibly quiet on the first 5 setting, from 1 to 4 you wouldn’t even notice is on.
Cero Vibration from the motor, well built control panel and easy to set up.
The only complaints I have with the item are:
1. comes with the European plug so it needs an uk adaptor, which is included but it make the plug twice bigger than it should
2. The straps including with the fan feel really cheap, in fact, it is the only thing that that’s not look or feel premium
This is a great produc. The monitor helps with the grow.

AC Infinity Cloudline's are absolutely amazing! I have a T6 and T4. Both are super quiet. The T4 has a newer controller with a few newer features than my older T6, but both are quiet and work well for keeping my grow conditions where I'd like them. Will definitely be buying a couple more, later, and the new AC Infinity Controler 67.

Incredibly Quiet Exhaust Fa
Decided to replace an older bathroom fan in our downstairs bathroom. The heater had failed and it honestly sounded like a freight train when you turned it on. My son wouldn’t use it because of how loud it was and how little air it moved.
Shopped around at the local home improvement stores and tested all of the standard models and none of them were really any better. If they were quiet they didn’t move air, if they moved air they weren’t quiet.
Ran into a post about the AC Infinity line. Although they were designed as grow house fans the ratings were outstanding and they met my two requirements. Move a lot of air and do it as quietly as possible.
Ordered the T4 and it came packaged amazingly well with great directions for the use of the remote control. Hooked it up on the kitchen counter and man, it was quiet! Also moved air like crazy. Sure there is always going to be some noise and vibration when you have it on full speed, but when you run it at half speed you can barely hear it and it will clear out a standard 8×10 or smaller bathroom of moisture in just minutes.
A few notes on installation for a bathroom.
1. These were designed to be used in a grow room installation. The mounting options for the controller box are limited. You can’t flush mount it and I wasn’t able to find a mounting bracket that would allow it to be installed in a wall. Had to mount it on the wall. Looks ok but the cables can’t really be hidden.
2. The power is plug in only, so if you want to hide the cord you’ll have to install an outlet or have access to an existing outlet. I suppose you could cut off the plug and hardwire it, but the manufacturer suggests not to.
This is an amazing fan and I’ll be adding them to the other bathrooms in my house as well. Hoping AC Infinity comes up with a flush wall mount or a different controller design. Also a hardwire option would be fantastic. For a product this good they are so close to perfection.
Don’t need a box or tape to ship.
Fan seems to work fine. Box was smashed and open when I received it. No shipping box was used. No tape was used to close box. See picture of label on box. States “Do not ship as is””Use additional shipping box”. Ironic, huh.
UPDATE
Installed today, this fan super quiet next to the other brands and I have one right next to it. Really like the controller with temp and humidity. Awesome fan, Lousy shipping – I see Amazon shipped, so what happened?

Works ok. Fairly quiet. The controller is very limited.
I purchased the T4 for a small space. It was very easy to install.
I always want the fan on, so the controller/sensor arrangement is useless for me. Just added expense.
As advertised, it runs surprisingly quiet. The motors step up and down very smoothly.
The absolute best purchase ever.
Wow what a fan, I was having trouble getting and keeping my grow tent temperature stable, I tried fans exhaust fans everything I could think of, Finally I ran across this infinity 4″ inline fan and was very impressed with it, I installed this in a 4×8 grow tent and set the controller to my set temperature and humidity and this thing is amazing the best money I have spent ever.
I have my temperature set from 75 deg to 80 deg and my humidity from 50 to 65 and fan keeps the temp and Humidity inside those settings WOW,
This fan is amazingly easy to set up and is super quiet. I have had this fan installed for 2 weeks.
Best purchase every you will be very happy with this fan.
Although I really like the design and the build quality, I find there are other options available with a more reasonable price. I bought this exhaust because a friend recommended it to me, so I had some high hopes about it. I was expecting to do an upgrade from an old exhaust which was still usable.
While I initially planned to acquire the less expensive model S4, in the end I decided to go for the T4 model since I really liked the temperature and humidity control.
In regard to the noise levels, the device has acceptable levels while working on the settings 1, 2 and 3. However, when the fan speed is on level 4, it makes noticeable noise, and level 5 is extremely loud. Since the device is advertised as a quiet inline fan, I was expecting moderate noise levels on medium speed.
Overall, Im disappointed I didn’t go for the S4 model because the controller did not work for me.
Nevertheless, the customer service from the firm is excellent, they solved my problems is less than a day.

These are just absolutely great. Love the fact you can use one controller on 2 fans irregardless of size. The multi-level of controls, alarms, temp and humidity are just incredible. Won't deal with those out 'bargain' cheap imitations.

Excellent quiet, very quiet fan. Lovely bit of kit. But it’s controller can be very dodgy and common problems with the humidity and temp controller run together, of it turning extract off if humidity low, both fans in fact, or start stopping, etc. So they released, hey presto, and NEW Fan Controller, because this one is pants. Get the S4 instead and an S6, or 2 s6Cloudlines if you have the room, and buy the new smart controller. Sorry I got the T4 but i needed a silent fan, so just run it dumb. There were no S4s as theyre as rare as rocking horse poo poo.
Awesome product.
I normally do not write reviews, but this company earned a praise.
Such good product. And I mean all around. The box, the instructions, the finishing of the product itself, the quality of the materials and the fact that they “just work.”
I have to give it to you guys… good job!
I have a cabinet cooler and an in-lone fan from this brand and I would 100% recommend them.!
looks great sounds quite as can be, use in our bedroom grow so we sleep next to it! works great top of the line!

My dryer wasn't very old was taking forever to dry
If you have a slow dryer this is your solution!
My vents were clean however the length of pipe was too long. This thing took dry times from 2 hours down to 40 minutes! Worth every penny. Very quiet. Love the flexibility of the digital controls
Easy to install, minimal noise on high setting, great for regulating temperature and humidity with automation via the controller. Would highly recommend.

I was able to get the duct tube that goes with this system (sold separately), securely over the system, however it was quite difficult and I can’t imagine how many people have ripped it bc they are dang near the same size in diameter. Great working device but I’ll agree with the other reviewers that 1/16th of an inch wider for the vent tube is needed but u can do it. Nice and easy 🤣💯

Everything about this fan is quality, even the packaging. Everything you need to mount it is included. Clear, easy to follow instructions. And this fan is quiet! No comparison, the PWM motor is the way to go. The smart control unit is easy to operate, easy to read, and there is plenty cable to mount it wherever you like. I bought the AC Infinity carbon filter as well, comes with a very nice tight fitting debris filter and everything matched up perfectly. And as a bonus, the AC Infinity products are beautiful! if you need ventilation, it's a little more money but you will absolutely not be disappointed.

Perfect. Very little noise. I have it on setting 5 out of ten and my 6” clip on fan makes more noise than this!

Great fans, mostly
These are great fans. I just ordered my second. There are a million reviews that extoll their virtues, so I’ll just skip to the two things that bothered me:
1. The temperature and humidity meters read high. I’ve placed the probe beside several other thermometers and hygrometers and the AC infinity consistently reads higher, especially the humidity.
2. You’d think the AC infinity carbon filter would fit into their own fan, but it’s much too large. That might be more the fault of the filter than the fan, but since they are so often bought together, it should be mentioned. If you’re going to mount the filter directly on the intake of the fan, be prepared to do some jury rigging. I just used multiple layers of silver tape to build up the diameter of the fan’s flange until it for snuggly in the filters flange. And then I tapped out some more.
Best fan ive used in my grow. Super quite. Works well, and display is very useful. I will be getting another one of these.

Definitely worth the buy. I saw a decrease in my electric bill after I installed it in my 4x4! The noise level is barely noticeable.

Quality
Easy to install ,very quiet , run perfectly
Very good quality
Great fan for the price and very accurate sensors!
I bought this fan when I bought my cloud lab 632 and was already impressed by the quality of the products. Assembly was incredibly simple. The t4 model comes with a control panel that allows you to adjust your desired temperature range and humidity. The one other feature I appreciate is how quiet it is. I also did a few test on how well the sensors from the panel worked and they were well above par. The one drawback I have is the ability to drop temperature in my tent(however that is due to my obnoxious 2000w light). Honestly it’s an amazing fan system for the price. Going to buy another to help out with the temperature issue, although I’ll go with the T6 this time. But no regrets!
*edit* after replacing the light with one with less output the temp is right where I need it to be

Buy it you wont regret it. You see the reviews its the best option for a small grow tent you do not need the bigger 6 inch fan. The 4 inch moves plenty of air in my mars hydro 2.3ft•2.3ft tent. Even on the lowest setting it does what it’s supposed to do so you can be precise keeping consistent temps and humidity levels this will definitely help. My setup is in the basement so it can get very cold so the digital display option definitely was a must for me and im sure it’s fairly accurate as I’ve tested it out. Great all in one feature. But one funny thing is the auto feature on the “smart” display causes the fan to turn to max speed when you have low humidity which makes no sense i don't know if they know but that is a big nono. But you don’t really need to use that auto feature, you can just control it manually and have it alert you when somethings off so overall it’s a good all in one product. Buy quality don’t be cheap if you have your own thermometer and humidity guage i would say you don’t really need the digital display they have an option without it as there is really almost nothing smart about it. Still pretty cool if you can afford tho.

Fully Controlled environments
Easy to install and set up the low and high temps and humidity alarms. Highly recommend for a fully controlled climate and environment.
Hey all, novice grower here. I needed an additional fan, did not plan on replacing the fan I had as the one I was using was loud but still worked, and I just needed another one. After using the AC infinity I decided to replace my first one and buy 2 ac infinity units as it's such an improvement, seriously, this is how all fans should be made. I spent my first year growing stressing about my inline fan, keeping humidity and temp in range, and the noise from a previous inline fan. I was constantly checking my humidity, speeding up and slowing down the speed to keep the humidity in range. I cannot tell you how much time and trouble this unit has saved me. I got a simple 6 inch inline fan with temp/humidity control. It's damn near silent at lower speeds, I leave mine running 24/7 and forget it's on. I set mine at 62% humidity, and literally haven't touched the controller for a couple weeks because I haven't needed to. ONE THING::: Read the instructions - a lot of the complaints I see have to do with programming of the temperature control. It's not super intuitive.

I had a different inline fan system that was so loud it would wake me up at night. I upgraded to the AC Infinity CLOUDLINE T4 and love it. It's quiet, it's easy to install and the temp/humidity monitor has saved my plants a few times. It's been running non-stop for about a month now and I have had absolutely no issues.

I got a simple 6 inch inline fan with temp/humidity control. It's damn near silent at lower speeds, I leave mine running 24/7 and forget it's on. I set mine at 62% humidity, and literally haven't touched the controller for a couple weeks because I haven't needed to. ONE THING::: Read the instructions - a lot of the complaints I see have to do with programming of the temperature control. It's not super intuitive.
Hey all, novice grower here. I needed an additional fan, did not plan on replacing the fan I had as the one I was using was loud but still worked, and I just needed another one. After using the AC infinity I decided to replace my first one and buy 2 ac infinity units as it’s such an improvement, seriously, this is how all fans should be made.

A bit pricey at 400 dollars to australia
It a quiet fan at low/medium speed, and at full speed it does push some air with some noise as expected. At level 10 is louder then they suggest.
Is it worth 400 dollars to Australia, yes, but could be cheaper for a fan. Dont know if it will last a long time, only time will tell.

I got home today to open up my AC affinity and it looks used There’s dust inside and on the cords look like they it’s been re-wrap the packaging doesn’t look right the whole thing looks like it was returned. Something brand new that’s been in the box on the shelf should not have dirt or dust inside of it in on it I need Amazon to contact me about this. I have not plugged it in or use it yet but I’m still gonna give it a review.

I am replacing all of the exhaust on all five of my grow tents with one of these in fact this should be the industry standard that kind of control it gives you is beyond anything else and of course a DC motor a lot quieter than an AC, if you care about what you are growing in your grow tent this is the in-line exhaust you need

This has turned my tent into a self-aware super tent that keeps my babies happy! Had it up and running in 30ish min. I felt comfy with the controller after an hour. It was the stone age before I got this! Shipped fast as well.

Nice product. Works great and does exactly what it needs to do without issues. I’ll likely buy this product again.

If you use twice as much fans as you need BTUs you can keep them down on speed and they're very quiet!

I bought this to replace an older exhaust fan for my grow room. Overall, it's a nice, but the 'automatic controller' only toggles the fan on/off, it doesn't ramp up the fan speed based on the temp/humidity set points like I thought. Instead, when running in auto mode, you set a fan speed and temp/humidity min/max values. If the attached temp/humidity probe detects a value outside the set ranges, it turns the fan on at the preconfigured fan speed and runs until the temp/humidity is back into range of your set values. Then it shuts off, which is where I have a problem. For a grow room, it be great to set a min fan speed and a max fan speed, then have it just adjust the fan speed based on the current temp/humidity. Since I'm using this to control odors, I don't want to exhaust fan to ever shut off. If I had known this was how this controller worked, I would've gone for the version of the fan with manual fan speed controller instead and saved the $20.

For me the ac infinity fans were a game changer, got my environment dialled in just how I need it and with ease to, I purchased an s6 and a t4 reasonably priced I might add, they work perfectly together! These fans are great quality and I was even more pleased when they already came with a connector attached to a U.K. plug!
Overall 10 out of 10 for these fans, hats off to AC infinity, they’re so quiet and just a quality product, I will never use another make again, if you’re thinking about buying one just do it, you will not be disappointed
Super awesome! Best fan/filter set up ever. The handheld controller is a must now. I was always opening my tent to check out temps/rh. Now my girls can grow uninterrupted. No noise as well. Great combo! Glad I purchased. I should’ve purchased this years ago

After applying the easy to use settings, just forget about it and it does it's job! Very quiet as well.

Retired HVAC Tech. For my use on bathroom ventilation. I will say these are sweet. Very well made. Quiet with a large display approximately the size of a single gang box. Impressed with the quality. Easy to read instruction easy to hook up.

My PC sits under a desk where the heat gets trapped especially when rendering videos. After years of suffering from toasty legs, this is great in winter but not so in summer, I decided to get this plus matching hoses. Screwed it under the desk, routed the input from the desk and output to the window. The thermal sensor lets me not run the fans only at threshold temperatures. It can be loud beyond Speed 6, but it is effective.

Muy buen producto y lleg antes del tiempo estimado, exelente eleccion recomendado
I dislike how everyone is not reading directions and programming this item correctly and trash the product because of their own stupidity 🙄

Beautiful, quiet, efficient and professional looking
I have been loving this fan for 6 weeks now. It’s perfectly quiet and efficient. It tries to bring down the temperature of my area with the fan on low speed 1 first and then it moves to 2 if needed. It looks very professional in every way. The digital display also exceeded my expectations as to how easy to view and how easy to configure.
But the cherry on top was tech support. I thought I was missing a power cord for the display, but its powered from the fan – doh! I contacted them and they quickly answered in email and were extremely helpful. There is no better fan for the money, plus you have great tech support ! I’m rarely impressed buy a product this much and I buy something daily from Amazon.
Quiet. Powerful, light, great sensor, top quality packaging. Will not buy a different ran from now on!

Awesome. Much quieter than similar products from competitors. I have tried the cheaper fans and put of frustration bought this one, paying a little more. I wish I had just bought this one to start.

These fans are great. Probe to monitor tent temperature & humidity. Cooling my little tent off on 4, which is super quiet.

Very very impressive bit of ki
I’ve tried four different fans over the last couple of years, looking for one quiet enough – this is amazing. It is barely audible up to about level 6, it’s small, light and feels very well made. The temperature/humidity controller works really well to maintain a steady environment, basically, this has massively upped my game. I can’t recommend it highly enough. I’d like to know when ACInfinity are going to start selling their tents over here too as I would really love one

I like this product because it is super quiet and energy efficient. My only issue is that the programming is primitive in that it cannot be programmed to keep a certain temp and relative humidity (RH). For example, when the sensor reads the set temp and RH the fan shuts down completely. On the other end when the temp or RH exceeds what is set the fan jumps to max speed (10/10). So what happens is the fan goes from 0-10 the whole time it is trying to maintain your ideal environment. From what I’ve read is that this is a particularly advanced function to be able to build for a controller, but I have no clue because I am not an expert. Just a consumer. Overall, I love the fan itself for its stealthiness and its energy efficiency. I hope that ac infinity creates a more advanced controller.

I already own two of the AC Infinity 4 inch fans and I love them. There are plans to buy at least 1 more. The amount of control and this fan offers for tent growing is absolutely the best. I had a cheap white plastic fan from another grow tent kit, it's a day and night comparison. AC Infinity hands down is the winner.

Fantastic vent for a 4x4 tent!!
Excellent vent system! Very quiet and powerful enough to run a 4x4x7 tent with ease. It struggles a bit managing a 4x8x8 room.
Controls are easy to use, it’s sleek and looks nice and very well made. It’s extremely quiet!
Keeping these in my arseanal !
Quite and strong. Started the 4”, but shortly upgraded to the 6”. I highly recommend you purchase the 6” from the start. Love being able to adjust the fan from outside the tent. Great produc

Nice piece of equipment so fa
Works well. Taking a little time to balance the high and low alarms between humidity and temp.
The fan is smarter than my other equipment.
Incredibly impressed by this inline fan!
So impressed by the quality, packaging, and thoughtfulness of this inline fan that I ordered another, as well as some smaller fans. It was packaged better than an Iphone, the documentation was very thorough, and it was assembled in a way that made mounting it a breeze. The finish/quality is quite good, and the control module has worked perfectly. It doesn’t go straight to max power when it hits the temperature threshold, but ramps up as needed (which is a bonus because it hasn’t woken my wife up once, who was NOT happy with my amateur sheetrock cutting skills…oops).
I wish AC Infinity branched out to manufacture more items, because they’re nailing it with quality products at a reasonable price.

To have it “automatically” turn off and on... you need to set the alarm. The alarm is NOT quiet. If there isn’t a way to silence it.. which I haven’t found... this is a design flaw. Fix that please and send me one of the NEW units!

Great product gave it a 4 out of 5 because the temperature probe that came with it never worked but I didnt need it too so I only took one star off all I can say is I never trust those anyway and I have other ways of checking humidity and temperature that I use to dial in my fa

I used the fan to ventilate a cabinet area that houses the sump pump. It was easy to install, works like a charm.

Excellent quality, quiet, good airflow, easy setup, controller is nice and has great functions and information, every function is fully customizable and programmable. Time will tell if it holds up to long term 24/7 use, but appears to be a very high quality product. I am very happy with the fan.

Goal was to add ventilation to bedroom in basement apartment. This did the job perfectly! Understanding that these were designed for grow tents, I was uncertain how to adopt to my application. Here are details: bedroom 11 x 14 x 8’. No window to provide fresh air. Installed AC Infinity wall vent plate high on wall opposite door, then 8’ of AC Infinity 4” pipeline to the T4 fan, in neighboring utility room. Not vented to outside, as this space has ample opportunity to vent back into the apartment. Programmed to turn on at warm temp or high humidity. We run fan at low speed through the day. This unit is seldom run at more than setting “5”.
