This fan is easily one of the best things that's ever happened to my garden. No longer am I at the mercy of my 4" and 5" inline fans with no variable speed controller. The fact that it comes with a digital display with settings is a HUGE upgrade. I'm finally able to effectively dial in my environment without guessing what this week's weather is going to bring me. The fan was simple to set up, and comes with a bunch of accessories and their ac infinity venting fits over these fans nicely. Indoorfarmer.ca is pretty famous for their shipping and customer service by now if you haven't really got around to ordering through them.

I personally have two of these that I love so much that at work when looking for something to exchange air in a sealed booth I had to buy two more of these. At first I wished I had sprung for the 8 inch or above but after a successful harvest, and looking back at the historical data of the environment, I am completely satisfied with this one. Its an awesome fan by itself but turns any novice into a pro when coupled with one of the controllers. I run the 69 blue tooth and 69 pro wifi and love them both! I probably shouldnt say it but I would have paid so much more for these products to get the control I am getting with them.

Great inline fan. I am currently running 2 of these. 1 is exhaust hooked up to the charcoal filter and the other is for air intake. Promotes great circulation. I am super happy with not just the products, but the packaging as well. When you open the box, you know right away you bought a quality product. Price is really comparable to everyone else but the quality goes way above and beyond. I will continue to purchase through AC Infinity as long as they keep up their excellent business model and top of the line products.

I don't get it? This thing is supposed to be top of the line. The aesthetics are cool. The technology with the sensor and the meter readout panel features that make it more appealing. The whole design of the fan looks great. When the fan powered on it was much louder than I expected, even louder than what my iPower vortex 442cfm at same negative pressure. I believe it's louder because it has to work faster to achieve the same results as my iPower fan.Then when you crunch the numbers of the electrical current juicing the fan it isn't exactly what it's cracked up to be. In fact, two of two fans only operate at 80% the specs on the sticker. The readout on the display panel may say 80%, or 90% of the 402 CFM, but that's based on .94 amps. When in actuality the display ... MoreI don't get it? This thing is supposed to be top of the line. The aesthetics are cool.

When in actuality the display panel says 80%, or 90% of the actual .71 amps. The specification sticker on the fan says 70W, actual 58W. Says .94A, actual .71A. As a result of the lower current than specified the fan is unable to achieve it's specified CFM draw. Due to this malfunction this AC Infinity cannot achieve full negative pressure in a 48"×48"×80" tent. It seems clear to me that people are so attracted to it for features and aesthetics that it blinds them from looking into it's functionality. It's become apparent to me that in the past 10 years quality control has gone by the wayside 8n the manufacturing liney.
My Drymaster motor packed a sad and would have cost$1400 to replace. So I went on line and found that the 150mm AC Infinity series would do the same thing. I found it very easy to fit. It is slightly more noisy but not enough to worry us. Rang up and talked to Josh who was very helpful and I down loaded the app onto my new phone but it would not connect so I just used the display. I found Josh very helpful and under standing of my lack of technical know how. we are now back to not having wet windows. Thanks for all that. Ivan.
I've been running this fan for 3 years and was already extremely impressed. After recently adding the controller 67 (which now comes stock) its phenomenal, set and forget, the fan pulses airflow to keep my humidity and temp stable with minimal fluctuations. I also have the S4 fan, was so impressed I just got a controller 67 to add to that too. I've noticed some reviews questioning the pricing here. I used to buy direct from AC Infinity as, even with shipping, it ended up cheaper. Everytime I make a purchase I always do my homework for the best price, and don't rely on past info, things change. Enter these guys, all things considered, best price in Aus. I say all things considered because you may get the fan cheaper direct from AC Infinity, but when you factor in ...

Enter these guys, all things considered, best price in Aus. I say all things considered because you may get the fan cheaper direct from AC Infinity, but when you factor in shipping, usd to aud conversion and the fact that you'll have to buy an additional US to AU power adapter, there is no way I could swing it to get it cheaper from the manufacturer and that's with 15% discount code to mind you. Not to mention faster shipping, local customer support (which after a couple of mistakes on my part, I found to be great) and local warranty under Australian, not US standards. You've got my business.
I needed a high volume quiet fan for my home and got the Cloudline S6. I designed a heat transfer system to take hot air from my fireplace and transfer it to a colder part of my home. The order literally was beamed to my home, fast is an understatement, we're talking less than a week without expediting. Setup and electrical is geared for the novice. I was amazed at how lightweight it is. It is made from a thermoplastic of some kind and I'm not sure if anything is metal, short of the rivets that hold the intake and exhaust to the main body. The other amazing thing is how quiet it is; we're talking new "refrigerator" quiet and there is no perceptible vibration which would make one suspect that the fan wasn't working except that there's air coming out. As for volume. ... MoreI needed a high volume quiet fan for my home and got the Cloudline S6.

The other amazing thing is how quiet it is; we're talking new "refrigerator" quiet and there is no perceptible vibration which would make one suspect that the fan wasn't working except that there's air coming out. As for volume. There are 8 settings and the practical setting for me is at level 2 to 3. At that level it puts out as much air as any good heat register I have. Lets just say that if I ever put this fan up to level 8 I would probably be able to warm up my dining room of 3,600 ft3 in a matter of minutes and not hours. Be aware that the noise that does exist is the air flow duct noise; if your duct interior is metal or sheetrock, there will be noticeable noise. I used 2" insulated wire coil plastic tube ducting on the discharge and I can't hear anything except my refrigerator., and mind you the fan is situated only 2 ft upstream of that register. I would recommend this product. Long term reliability I can't speak about, but this fan uses hardly any electricity and I know using this heat transfer system will reduce my portable electric heater costs. I have a 9 month winter so I know it'll take maybe two years to pay for itself beside keeping my dining room a whole lot warmer for less money.
Not sure if it's firmware update that's the problem, but suddenly today my t6 quiet isn't turning on to manage the heat. (Note, the whole time the 69 Pro controls page on the app has been unresponsive. Each time I change anything, it sends a message saying it's down for maintenance, and changes back. But that's always been that way.) I woke up this morning, checked my app, and saw my tent overheating. All the settings were the same, and the temp was almost 10 degrees over the high setting. So I fiddle with the app, and get it to turn on, then a couple hours later it's doing it again. I just bought the whole AC Infinity catalog 3 weeks ago, and have a nice 3 week old baby girl in there. Now this, I really need this resolved ASAP. I guess I'm still in the return ...

Absolutely the best inline fan I have ever purchased! I cannot fault the AC Infinity Cloudline T6, the build quality is fantastic and it is the quietest fan I have used (and I've used a few) and the EC motor is very efficient. The included controller makes it easy to control your environment with high/low temp & humidity settings and is a great feature. Don't be fooled by cheap imitations of this fan, with similar controllers, they pale in comparison to the AC Infinity Cloudline. What really impressed me though, was the communication and service from Herbal House. Absolutely top notch and possibly the BEST customer experience I have had when buying equipment, Chur! Will definitely be back for more :)
This thing is so awesome. Fully speed adjustable with parameters for low and hi temp, low and hi humidity and timers as well. Runs from an easy to use app on your phone or through the controller itself. And on full tilt it would probably suck a normal sized domestic house cat or a small child right through. Or atleast any excess heat. The app stores data and shows graphs for up to a year! How good. *I dont know if its the best on the market cos i dont know a whole lot about inline fans. But it is. Probably. Who cares just buy one you wont regret it. I'm buying another kit so they must be good, right? Also, as always, 10/10 service from the guys at Herbals. Hopefully you guys will be getting in the AC Infinity oscillating fans when they are released? Thank you for ... MoreThis thing is so awesome.
