The AC Infinity exhaust fan is a top-notch choice for anyone needing effective ventilation. It’s incredibly efficient at moving air and keeping spaces cool, which is perfect for managing heat in various settings like grow tents or workshops. The fan operates quietly, a major plus if you're sensitive to noise, and the build quality feels durable and reliable. Installation is straightforward, and the adjustable speed settings allow for customized airflow.

I am writing this review for two reasons. The first reason is the Cloudline T4 fan unit itself, and AC Infinity's awesome customer service. The second reason is the title of the review. I am not using this in a grow room, but in an encapsulated crawl space as an exhaust fan.This fan is outstanding. It was easy to install and setup. For my use, I just have it strapped to a short cinder block and sitting on the floor of my crawl space. I have a Vivosun duct cover over the intake, as the intake is not connected to anything, and I didn't need a carbon filter for my application. I then have the AC Infinity 8' ducting connected to the hard duct that exhausts to the outside.My Fantech FR-100 was pulling way too much air, causing too much negative pressure in my townhome, and causing too much noise, mainly from bad mounting and thus vibration noise. The FR-100 was literally shoved into the hard duct, sheet metal screwed on, and then duct taped. Basically, just hanging there off of the hard metal duct.Anyway, I was wanting to know the CFM ratings per fan speed settings, and AC Infinity support was awesome, quick, friendly, and got me that information fast through their chat.The other issue I had, was the FR-100 was way too close to the inside floor intake vent, about 5' away. This made for uneven temps in my crawl space due to lack of air circulation. Air pulled into the crawl space and exhausted right out. With the T4 and ducting, I was able to place the fan much further from the intake making air circulation better and thus I now have more even crawl space temps.My crawl space is small, about 250 ft, and per code, only needs about 5 CFM. Setting 1 is about 45 CFM, and I am currently set on level 4, about 100 CFM. This in part due to the dust cover lowering the actual CFM and a backflow air valve on the intake from the house. I need to create enough pressure to make sure the valve opens and I was testing a few things. I will like lower the level to 2 eventually.Anyway, this Cloudline T4 fan, is truly whisper quiet. At 10, I am sure there is some noise, but in testing up close, from levels 1 to 6, you could barely hear it at 4 - 6.Overall, I am super impressed with the Cloudline T4 and its smart controller (which I will be upgrading to the WiFi model).

I bought this to replace a bathroom exhaust fan. I gutted the motor and cage out of the old one, used the power feed to power an outlet for this unit up in the attic and installed the fan between the old housing and the exterior vent. I drilled a small hole where ceiling and wall meet to poke the sensor out and installed the control on the wall just below. Set the fan to turn on at certain humidity and temp levels and forget about it. Now I don't have to worry about excess moisture causing mold, etc. Not sure it was designed for this but works like a charm and is quiet. Much cheaper than the Panasonic fans I was looking at and a higher static pressure to pull that moisture out.

I'm disabled, so dont have an income that allows me to do much. But I can afford ac infinity items, because you need only purchase them once, and they do what they are advertised to do.I've purchased AC Infinity products, now, for several months, 3 gallon grow bags, the 4" inclined fan and controller, air plates, and several other of theyer fans to control the small closet I've turned into my grow room. I will get self watering systems, soon hopefully, but ac infinity does all the work for me, and soon all I'll have to do is watch them grow.I still plan on getting the 2x2 tent they offer, soon, and will gett more fans, still, and a dry tent. Theyer products are exceptionaly made, quiet, and energy efficient. Im not a professional grower, but AC Infinity, makes me feel like I'm on the right path, with the choices I've made. I will continue to by my products from AC Infinity till a better product line comes along, offering better quality, and user friendly products. I dont see it happening any time soon, so I'm very happy with all I've purchased from AC Infinity. The 4" inline fan works and move so much more air than i thought it could displace. And its so quite. The controller makes every thing almost plug and play. Easy to understand directions, witch i definitely needed, but instructions walk you through it. And theyer are hundreds of you tube vids, to help walk you through it, easily. AC Infinity will continue to be my go to choice for my grow room. My grow Loves them, and I Love what I grow, so my choice has been made for me. Bit it's really just comman sence. Thank you, AC Infinity, for maken my life easier. A very happy and satisfied customer.

This fan is just awesome, a great piece of technology. Smart design, extremely quiet and very powerfull. The fan is totaly versatile and will start up depending on the options you picked. If you want the fan to start when the room is too hot set a temp, maybe you want the fan to start when its too cold, again just set the option. Humidity to high or low, set the easy to operate keypad options. I use it for my grow-op (Legal in Canada) the fan brings in fresh air during the day when the lights are on and keeps the temperature I picked (75ºF) precisely. At night the fan doesn't kick in as the lights are off and the temp drops automaticly. Also great about this fan is the variable speed that adjust the amount the room needs to cool down or up depending on what you chose. Hate to go on and on but I just love this product and I think you will too.

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.

Ich habe das Produkt seit einigen Wochen in Nutzung und finde es bisher sehr gut.Es hat versch. Leistungsstufen, bis Stufe 4 läuft das Gerät sehr leise. Zur Absaugung eines Anbauzelts 160 x 60 x 60 cm reicht auch Stufe 1 bereits aus!Software ist ebenfalls top: Tracking der Parameter Temp. + rF erfolgt minutengenau und bspw. remote übers Handy (also auch unterwegs). Alarmgrenzen bzw. Aktionsgrenzen der Parameter können ebenfalls jederzeit remote konfiguriert werden.Kleiner Minuspunkt: Gerät kam ohne Adapter fuer deutsche Steckdosen, musste ich fuer ein paar Euro nachkaufen.Fazit nach vier Wochen: Note 1.
