CLOUDLINE S8, Quiet 8” Inline Duct Fan with Speed Controller - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics

Good quality. Very quiet. Using for 1.5 years. Excellent quality

パワー感は、どうかな？ と、いった感じです。

The brand is one of the better manufacturers selling to the general public and the vendor was very supportive and provided prompt service. I would buy from them again and recommend the inline fan without hesitation. It’s quiet at lower settings and works without issue.

AC Infinity has changed the game of home growing for everyone. This fan is priced very well for the level of quality and features it packs. I plugged it into my AC Infinity AI controller and it detected it without hardly any intervention. Since I am not growing plants, but gourmet mushrooms I needed to disable the AI (broke my heart because its truly amazing) and set it manually at the precise numbers I needed. High humidity and low CO2 for fruiting. I had trouble getting it to accept the numbers I wanted since I was not growing standard plants. Called support and had Judy on the line with zero wait time. Judy was a controller ninja and walked me through the clicks to get exactly what I needed set up. Perfection! She didn't ask a million questions, didn't have to go through a painful data collection pre call, just picked up the phone and asked how she could help me. I explained my issue and she had a solution in minutes. Made sure it worked for me and was a pleasure to work with. I don't call support for anything, even at work, unless I am totally dead in the water with no options. AC Infinity made me rethink this stance. The fan itself works great. 10 different settings. Perfect for a mushroom grow tent thanks to the true waterproof rating. Humidity won't even touch this thing. The fan looks sleek and runs silent. I see there is a sound damper available but can't imagine why one would need it unless they sleep next to the tent because its so quiet. The setup was quick and easy. It moves a ton of air and keeps the FAE spot on in my tent. I love the AC Infinity products. I already had a fan and filter and 2 humidifiers that I swapped out just so I could use them with the controller and have more matching gear. I want to set up a garden inside now since this system is so easy to use and works so well.

This is really an impressive package from top to bottom. I've been buying AC Infinity products for many years now and have always been completely satisfied with everything, this is no exception. The difference is this is the largest, most important, and most expensive thing I've ever bought from them. I bought the 12" Pro fan to use as a return booster fan for my home's ducted heat pump. I wanted it particularly to boost the return air upstairs in my house to assist with cooling and dehumidification because it gets so much warmer on the second floor. I programmed it to always be running at minimum speed, trigger at 70F and then increase in speed by 1 notch for every 1 degree F rise in temperature beyond 70F, up to a maximum of speed 8. It will also revert to minimum speed at night, regardless of temperature. Setting all of this up was very easy in the app. I didn't even attempt it with the controller because I could tell it would be much more difficult. My recommendation is...just use the app. It was incredibly easy to set up and only took a minute. The quality of the fan is superb. I actually bought spring vibration isolators to mount it on since I installed it in my second floor in a crawl space (just sitting on the floor). I wanted to make sure vibration would not be a problem. However, it turns out I didn't even need the springs, the fan runs so smooth that there is no vibration or noise transmission through the house at all, even on the higher speed settings. The air noise gets loud on the higher speeds (7+), but the fan still runs so smooth that it is virtually silent downstairs. This is very impressive for a fan like this. About the package contents...you get a LOT. Way more than you will actually need. They include VERY long cables (the temp/humidity probe is about 25 feet), several different mounting options including a strap for hanging it and heavy duty screws, two 12" duct straps, and a bunch of zip ties and accessories for cleaning up the cables. All in all its a very impressive package. They do make duct fans of equivalent size that are capable of moving a lot more air than this, but those are very expensive commercial/industrial units and do not include this level of controllability and customization out of the box. If you want or need something like this for your home I can confidently say this is the best option on the market. I can't yet comment on longevity, but this fan will be running continuously in my home from now until November, so we'll see how it does. Based on my experience with several other AC Infinity products I own, I expect this thing will run perfectly for many years without issue. But I will update this review accordingly.

These fans ( I bought 2 - 4" and a 6") are amazing, the process was slick and efficient, it came in its original packaging and the seller sent them to Amazon ASAP!!! I will most def buy from them again, in fact I probably need 2 more, sooner than later.
