Review: Just what I expected from AC Infinity! And I don’t stand by any brands! - So I ordered this 3x3 tent on February 8th, 2021 from AC Infinity directly and I was patiently waiting for the T6 inline fan to go in stock because I didn’t want to get the carbon filter without having a way to test it but then I noticed it came in stock on desertcart a few days before the projected date for their stock direct from AC Infinity so I contacted customer support and asked if they’d help with an exchange/return if any problems occurred since I’m weary getting certain things from desertcart but all was well and they packaged the stuff in the original ACI’s boxes into an desertcart package so it protected it well and it eased my worries I’d be getting a knock off. You could set this up yourself but two people would be MUCH easier because I had my friend come over and help! They held the stuff up while I connected everything. The zip ties it came with were pretty short and I wanted it setup as an exhaust which I accidentally pointed the fan the wrong direction and I had to cut them anyways so I went to my local hardware store and got some 8inch zip ties which worked perfectly but I still trimmed off the excess to make it clean looking. The tent now has ZERO pressure at fan speed 6 with the carbon filter! In the video the fan sounds you’re hearing is not only from the exhaust setup but also the lights fans and the tower fan I have currently on in the setup at the time of this video. The arrows on the fan point in the direction of where the airflow will be going so if you want an intake you would have it pointing into the tent and if you want an exhaust you would want it pointing out of the tent but that’s just one way you can set it up since I saw on the ACI website they show you can have everything outside of the tent and achieve the same results! The speed can go up to 10 and sheesh that’s powerful I’m scared the tent will get sucked into a black hole haha but seriously it’s a really good setup for this 3x3 and I believe it would work fine for a bigger tent but at some point you’d have to get bigger than the 6” so just make sure you calculate how much CFM you’ll need. I was torn between this one and the T4 but I went with this one since I’d rather have too much airflow and be able to have it running at a low speed and achieve the same if not more than what the T4 could do on higher speeds! I was thinking about getting the silencer but I feel as if I have no need for it right now since the fan is like white noise and I’ve always slept with fans in my room and it’s just sounds like another one of those and I even think it adds more circulation into my room which my room has always been the hottest in the house so I’d even get this stuff for home use! I sadly don’t have anything to test decibels and haven’t seen how much power it’s drawing (I.E. electricity bill) yet but if I’m able to edit this review I will update that when I find out! I got the 25ft ducting cause it wasn’t expensive IMO compared to the measly 8ft and I’ve never used ducting before so I figured if I make a mistake I’ll have plenty to play with and I was right because the wiring goes in a spiral and I nearly was about to follow the whole spiral to cut it haha but seriously you need to get some good wire cutters because it was some strong a** wire! The controller it comes with I have yet to play with the various settings because I’ve heard some mixed things about it so I’ve just been manually turning it on and off which it’s the morning of Feb 19th 2021 and it ran its first run perfectly from yesterday the 18th and all through the night to right now as I’m typing and is still on just as efficient! If you’re thinking about getting anything from AC Infinity don’t hesitate because they will sell out fast! So in the video it was at like 77F and I can’t remember RH (Relative humidity) but now after I turned off the lights for more than 15mins it’s down to 75F with 45% RH!
Review: Works great and is very quite, well worth the money. - This is the second one I have bought over the last 3 years. The first one I bought was the 6" blower and I placed it on my Barndo to element negative pressure due the the building being spray foamed. It works great. The second one I bought is the 10" on my goodness at the air it moves. I put it on the main line feeding my game room that is completely on the other end of my house. That room has always been running 5 to 7 degrees warmer the the rest of the house. We could hardly feel any air coming from the vents. After installing it you can feel the movement of air and it cooled the air down to rest of house in about 10 minutes. I have it in auto and have it so it stays on setting 2 100% of time and ramps up as needed. You can't hear the blower at all. Supper quite and highly recommend.

## Questions & Answers

**Q: What are the cfm rating on it?**
A: From their site, "Duct Size: 6” | Dimensions: 7.9 x 12.6 x 8.4 in. | Airflow: 351 CFM | Noise: 32 dBA | Bearings: Dual Ball". Just installed one of these; a great little fan and quite quiet esp at low speeds. High speed fan sound is noticeable but it is really the sound of rushing air and not a motor sound.

**Q: Humidity and temperature way off does anybody else have this problem? Can it be fixed**
A: If all of you that have problems with these would read the instructions you can calibrate both temp and humidity as well as fix any problem with your fan not working it’s probably not turned on or is in the wrong setting check the instructions before blaming the unit these things are great in my opinion

**Q: Where is the humidity sensor? Is it on the sensor probe that also does temp?**
A: The probe acts as sensor for both temp & humidity

**Q: When unplugged and plugged back in will it return to the same speed as before? I want to add a switch to the outlet.**
A: I just tried it because of your question, yes it does, but I think you're asking about a timer situation, I would say that you shouldn't bother with a timer, the reason to get this fan over others is the programmability, this thing self adjusts its own speed based on the high/low temp and the high/low humidity that you enter, the power used to run it is very small.

### ⭐⭐⭐⭐⭐ 350 CFM @ 40w - If you want quality, good airflow with significant energy savings, do consider this
*by D***R on March 31, 2018*

I had been on a hunt for low power high CFM fan. I researched on centrifugal fans, mixed flow fans, EC fans. Giving the power consumption and features I settled with this one. Packaging was impressive and the parts themselves reek of quality. DC fan with Dual ball bearing fans are a welcome :). Parts included are; thermostat-controller console, temperature sensor probe, power brick, fan unit, 2 x ducting clamps The fan itself is much lighter compared to other AC fans (not surprising given the fact that power delivery is through a brick) Operation was fairly straightforward once you get used to controls on the thermostat/controller console. I have been using two of these (intake+exhaust) to cool off a mining rig and I am quite content with the performance. I have tried Active Air 6" centrifugal fan rated at 400 CFM. Though being a quality product, was too loud and consumed 105 watts. These are rated at 350 CFM at 40W with added benefit of thermostat control - smart operation. The fans are tad loud at high speed (speed 5-6) but not even close to other fans out there. Speed 1-4 are quiet for my taste. Following are the numbers captured from my test (see image below), CFM measured by converting from Ft/min unit measured by UT363 power consumption measured at the wall using Kill-A-Watt meter Noise captured using a cellphone app measured 3ft away from the fan (probably unreliable but you get the relative idea; active air used to be 85dB+ on this app) Electricity savings per month (considering 10 cents per unit) 40w vs 100w $3 vs $7.2. That's a $4 saving in a month from a single fan. Much more with when the speeds are lower and automatically controlled using thermostat-smart operation. Other thoughts Since this is a mixed flow fan it might not be good to have lots of bends in your ducting. For long ducts with bends, centrifugal fans are much more effective. My exhaust fan didn't suffer from reduced CFM due to bend when I ran it through a 6ft 6" ducting. CFM on intake end reduced by 40% because of filter. (YMMV) Warranty could have been at least 3 years because in comparison others do provide 3,5 or even 10 years (Vortex). However, arguably there are more points of failure for this unit.
