CLOUDLINE S12, Quiet 12” Inline Duct Fan with Speed Controller

Quiet, powerful exhaust fan. Using it for a whole house circulation. The remote can be interfaced with a microcontroller generating a pwm signal, for extremely powerful and customized control.

This is my second one of these (12"). Not because the first one broke but because I had an additional project. They are relatively quiet and push a lot of air. One has been running an exhaust for my metal shop for over 3 years and still works flawlessly. The second is running a DIY air cleaning system that I put in my woodshop -- barely hear it in the attic and, again, pushes a ton of air. Recommend.

Fine

Read: if you have a 12” supply line running it the upstairs of your home and the air conditioner just isn’t pushing the air to the registers, get this!!! Installed one in a 2700 sq ft two story home with the furnace in the basement, there is now measurable air reaching the entire top floor. And the best part is you cannot hear it from outside the utility/mechanical room, even when running at full power.

I purchased the 8spd setting basic model Cloudline 12in (not humidity controlled) . Its a powerful beast.. Of course AC infinity's inline duct fans are as quiet as you can get for what they are. I needed a high static and cfm fan for my hood at my glasstorch table.. It runs nearly 24/7 for months now at setting 3-4.. then setting 7 when working this way i maintain air current in building 1 direction further increasing safety of glass dust ect. . Will be disassembling for a routine clean soon but honestly this thing has worked great for me. passed every smoke test and has maintained good pressure for quite awhile in a workshop environment. Meeting and exceeding my needs so far. . Ive used ac infinity for many projects requiring airflow.. Hope their quality never changes cause so far they have a fanboy in me.. pun intended.. :D

I really like the volume of air this fan moves. I use it for a whole house fan when the air outside is cool! It is very quiet on the lower settings.

I purchased two of these fans, and both failed shortly after the 2 year warranty period expired. One lasted 31 months, and the second died just a month later. When I contacted support, they suggested I purchase a $30 controller, which ultimately failed to resolve the issue. Upon inspecting the internals, I discovered that the electrical boards on both units had failed, with visible burnt components. While the company claims a 67,000-hour bearing lifespan (roughly 7.5 years running 24 hours a day), it is irrelevant because the electronics are prone to failure within three years. Their offer of a 20% discount on a future purchase felt insulting given the premature failure of both units. Having used at least a dozen inline fans from various manufacturers over the last 20 years, I have never experienced a failure until now. These fans use cheap components and lack the reliability advertised. I regret not choosing a more reputable brand from the start and cannot recommend this company based on my experience. I am giving them two stars instead of one only because the fan was noticeably quieter than others I have used; however, the lack of durability makes it a poor value.

This this BLOWS! Holy sheet, its insane on max. Big boy cfm's. Really happy both worked out of the box.

I bought this to replace an existing failed 12" inline boost fan for a home ventilation system. I'm going to be quite critical because I'm comparing against another EC fan. A summary of my review is that I think this is quite a lazily designed product to be demanding such a high price (£350). More professional options are not that much more expensive, but offer far greater quality. This seems to be an example of a compact EC motor being slapped into a shell designed for a bulky AC motor. The benefits of a smaller, energy-efficient motor are not taken advantage of. First off, it does work and sort of meets some of the basic claims. It can be controlled by PWM - if you replace the silly USB-C cord (I take personal offence to this inappropriately used connector for 10-volt PWM signals). I connected this up to a Shelly for WiFi speed control. It does move a lot of air at the top speed and can be slowed down to a very quiet level. The next thing anyone will note is how loud it is. The volume at full-speed is expected, and it can run very quietly at low RPMs. However, everything in-between is kind of closer to the louder-end of what I hope and expected. While installing, I found the 12" diameter to be a bit of a loose claim (heh). This doesn't follow the normal conventions expected from other 12" ducting products. Specifically, the outer diameter of the inlet/outlet is 300mm rather than the usual 312-315mm, this means that existing 12" ducting was more than just very loose. It's a good thing that I decided to replace the mains cord, because it seemed the cable grip had badly crushed the cord. These sorts of fans are always marketed for hydroponics (hmm...), but one thing I noticed quite taking a closer look was the general lack of sealing. If it does meet IP44 specs, it does it very barely. I don't expect this to survive much condensing humidity.
