    • Crawl Space Exhaust Fan Goodness!
Size: 4-Inch PRO, Smart Controller
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). ... show more

    • Great fan at a great price
Size: 4-Inch PRO, Smart Controller
Review Image by Steve R Steve R
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. ... show more

    • The lil fan that does
Size: 4-Inch PRO, Smart Controller
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. ... show more
