Review: Powerful exhaust fan and controller - As soon as I got my S44 light - I was hooked on AC Infinity's build quality. And wanted to have better control over exhaust heat & smell. This kit is perfect for my 4'x4'x80" tent. Sets up easy, came packaged really well, and works like a champ. It's a bit loud when it ramps up to full power, but it also moves a ton of air quickly. Mine spends most of its time around half power, and is pretty quiet there. At full power, it's comparable to a window A/C unit. They've got duct silencers available if noise is a problem. Tons of included mounting hardware, plenty of ducting. All very high quality in build and look. The controller can be a bit confusing to set up at first, but they have a YouTube video that explains it all pretty quickly. I find setting up advanced automations is the way to go, as that will override any default settings and you can have any number of custom triggers and high / low settings for specific schedules, as well as transition points and buffers for smooth ramping of fan power, etc. The data graphs on the app are fantastic, and make it a lot easier to tweak the setup for ideal conditions. Highly recommend this whole system, and am adding one of their humidifiers, another clip fan, and the outlet controller for a small heater soon.
Review: First rate quality as usual - I’ll start by saying this, if you are worried about discrete packaging then I’ll put your minds at ease. When you checkout there is an option to have your item shipped packed in a plain desertcart box. Do that and your worries are at an end. BUT that’s not that important because it seems ac infinity has thought of this and no longer packages these with a big advertisement of what’s inside. It does have a SMALL logo on either end of the plain box and in very small letters it says air filtration system but aside from that no big deal. I still opted for the desertcart box because I don’t want people getting the wrong idea. Now on to the actual product itself. Quality is top notch as always. Yea you can hear the fan on the highest settings but on 6 and below it’s very VERY quiet for the amount of air this unit moves. You’re really getting some high quality equipment here. Now onto the app. So far I’m very pleased with it. I grow sarracenia and I start thousands of seedlings in a grow tent for about a year before they go outside for their first dormancy. While a carbon filter isn’t really necessary for these plants, an exhaust fan is because they naturally like lots of light. The grow light I’m using doesn’t generate a ton of heat but on a warm day the temps can rise past 80 and I prefer to keep my plants in the mid to high 70’s. This fan and controller have allowed me to keep my climate within precise parameters from ANYWHERE. I love being able to monitor my tent while I’m at work. It definitely offers peace of mind. Well worth the money spent! If I were to purchase the inline exhaust fan, controller and other extras seperate it would definitely add up to more than this whole kit. The way I see it the carbon filter is a nice extra. Like I said I don’t need to get rid of any smells but I set it up to filter incoming air when the exhaust fan comes on when the temp rises above 80F Ac infinity always impresses me with their quality and attention to detail. It really is top notch. You can’t do any better. I’d be amazed if any of the similar units are anywhere close to this level of quality.

## Questions & Answers

**Q: Will this be good for 48"X24"X60"  tent ?**
A: I use in a 4x4 tent works great.

**Q: For the manufacturer: I’d like this ventilation kit in the 4” size, but with the wifi version of the controller. Is that possible?**
A: Yes totally possible. I think its about 160ish with the remote as well. I opted for the speed controller bundle instead of the wifi controller and i regret not going with the better one. So good thinking on your part to go ahead for the better one.

**Q: Is there a warranty available on this it is not showing up when i addit to my cart ?**
A: All of AC infinity products, except consumables, are under a 2 year warranty. You just have to provide the order number, and confirm your address and AC infinity will replace or repair the defective product. Very easy replacement

**Q: Is the filter also inline with a 6" inlet and 6" outlet?**
A: The filter can be utilized either pulling air out, or pushing air in with the inline fan.
