## Description

desertcart.com: AC Infinity CLOUDLINE PRO T8, Quiet 8” Inline Duct Fan with Temperature Humidity VPD Controller, WiFi Integrated App Control - Ventilation Exhaust Fan for Heating Cooling, Grow Tents, Hydroponics : Patio, Lawn & Garden

Review: Awesome fan, very very quiet, with great airflow. Worth every penny! - UPDATE: July 2019 - This fan no longer comes with a "smart" controller, and now comes with a humidity controller. The biggest difference is that once it hits the set temperature it turns off (or on) completely. It does not vary speed with temperature. After purchasing a new unit last month I had to call AC INFINITY to order the old style controller, because I need the fan to always run at least at the lowest speed. FREAKING LOVE THIS FAN!! It is worth the extra money over a $60-120 fan. If you need things to be quiet,or need a smart variable fan (slower when lights are off, and faster when lights are on), than this will get the job done. It has 6 speed settings, with 1-5 being very quiet, and 6 being a little loud. Even though it is rated at a lower CFM than most other fans this size, the side by side hand test had me thinking this fan puts out 20-30% more air. In my specific example, I had a $80 fan 8" fan I bought a few month ago running just above its lowest speed (because of noise) and room temperature hovered about 88-90º with ambient temp of 80º. With this fan running at speed 4 or 5 during lights on.the room temperature hovered about 84-85º. The noise at this speed is at least half as loud as the old fan on its low speed, and temps are 5º cooler, WIN! Plus when lights are off the speed slows to 3 or 4 and I cannot even hear the fan any more. This is such a huge improvement for my indoor grow as lights off is during the day and I can no longer hear the fan. NOTE: The controller on this fan will not control 2 fans like on the 4" and 6" versions.
Review: Blue tooth operations and efficient and relatively quiet - This is an excellent fan. I purchased it to be used as a window fan. Most window fans for the most part are wimpy in comparison to this monster. This will give you wind output from a calm breeze to near hurricane force. The volume level is not what is stated at 39 db. At a distance of 3 feet I measured the decibels at 75db on the highest setting of 10. That said, this was with no ducting attached attached. With ducting attached it dropped to 70db. I will likely be using the fan in the neighborhood of 4, which drops the sound level to about 57db. In my NYC apartment the ambient level clocks out a 54db just 3 db less. So in this respect the sound is very quiet from the fan. Another interesting factoid about this fan compared to others is that it has a plastic body as opposed to metal. Normally, I would say metal is better, however the quality of plastic is excellent and it is definitely quieter than the metal housing duct and ventilation fans that I have heard. I think because the plastic amplifies sound less than metal fan housings. It's also quite efficient, although if you run it on 10 you're going to be pushing about 150+ watts, again higher than specs, but it is quite forceful if you need this kind of output. I will likely never take it above 7 which is in the neighborhood of 75 watts. To keep the fan dry I created a plywood hood covered with plexiglass, angle brackets and silicone. It fits in my window with a hole cut out for the fan to fit through. I engineered the roof of the hood at 45% slope to keep water and snow from collecting, and I added screening from home depot for the intake below to keep insects out. In this respect I can use it all year, although it's doubtful I will in the heat of summer. I also love the fact that it has bluetooth operations from my phone, and they actually have real people in their customer service department that are quite helpful. Recommended for the best possible window fan, provided you are handy with creating a hood. Also, likely very good if you are a grower or want it to move air from one area of your home to another.

## Questions & Answers

**Q: Basement cigar room. 2 questions:  Can this be mounted in the ceiling between studs with a drop ceiling? and 2: how many 6" inlets should be installed**
A: I’m using this for exhaust in my cigar room, third floor and open hang from the ceiling in a window bay.  For my space, a straight line single inlet was adequate.  I added a noise suppression canister so that acts as my 8” inlet.

For your purposes, it’s just a matter of how much space you have between joists, and even more so, between the flooring above and the drop ceiling.  The fan itself will work fin in that environment if it fits physically.  

Depending on your space, you might be fine with a single 8” inlet (or whatever size matches your fan).  If you need an additional inlet, keep them in a straight line if at all possible and make the one farthest from the fan smaller.  So if you have an 8” fan, you’d step the duct down to 6”, then a 6” inlet at the end of that, step the duct down again to 4” and have a 4” inlet at the very end.

**Q: Do you have to use controller or just plug fan in on a switched circuit?**
A: When I plug into the outlet without the controller, the fan runs. Not sure if it is set to the max setting. In case your controller is broke or want it to run continuously.

**Q: I need to mount this outside to blow air into a small space. Can it tolerate getting rained on?**
A: Yes you can mount it outside. As long as you properly shield the unit from the elements this fan will work beautifully to bring the outside air in, which is precisely what I did.
I created a window mount by using flat pieces of plywood that I cut a hole through that's just large enough to fit the Infinity cloud line t8 through a double hung window (actually the slightest bit larger) that I filled in the gap with gaff tape for a solid gasket seal. To shield it from the rain and snow I built a roof that slopes at a 45 degree angle so that all the moister jets off the enclosure. I filled in the triangle on the side so that all the intake air comes from the bottom of the unit where I installed a screen to keep all the insects out. Finally to create a lasting seal I added silicon to all the joints including a piece of plexiglass that I attached  to the 45 degree slope roof so that it is set for decades of whatever the outdoor weather presents. I have been operating this fan with this method for about 2 years including during heavy rains for days on end. I have had zero problems, and you will too provided you follow my instructions as a guide. This is the best possible window fan that could ever be created and has the huge advantage of being able to employ a flexible duct to direct the flow of air wherever you want it. Highly recommended as long as you are slightly handy and creative.

**Q: I lost the Intelligent programming device**
A: You should message the seller.  This is not a question.

### ⭐⭐⭐⭐⭐ Easy to boost HVAC flow to a hot room
*by B***N on May 12, 2026*

Used to boost HVAC flow to an upstairs room over the garage that always is hotter than the others even with the door open. Instant fix and it can now be 5 degrees colder than the hallway on level 4 of 10! Super quiet, WiFi app to tweak adjustments, less than an hour to install having never touched HVAC stuff before. I had a 7” duct going to a 4x12” register. I used the 8” fan and some 8”-7” reducers, HVAC tape and some big zip ties. Should have done this years ago.
