Review: Lazy product - 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.
Review: Fantastic deal - 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.

## Questions & Answers

**Q: hello,i gonna use it in my grow room.
do i really need the carbon filter while using this fan?
if yes,can i use other brands carbon filter with it?**
A: This machine just blows air in or out.  The carbon filter get rid of smell. Two different things.  Yes, you can use a different filter mix and match equipment.

**Q: Is there no option to buy 2 fans and 1 controller?**
A: No there is no option for buying 2 fans and 1 controller. If you do buy 2 fans I would get 2 s models and buy the controller separately. Saves a little bit of money and get the same results!

**Q: I have read the reviews discussing the sizing issues with the inlet/outlet sizes being more 12.25 instead of 12.  Has this issue been corrected?**
A: If your trying to put that 12 inch flexible ducting you basically cant and just have to get aluminum tape. Its not that big of an issue though. With the tape it stays put.

**Q: Can this fan be used to exhaust kitchen hoods (e.g. inline connected to a hood liner)?**
A: I would not use such an expensive fan for a kitchen exhaust hood. The condensation and grease steam alone would gum it up and ruin it. They sell hood exhaust fans

### ⭐⭐⭐⭐⭐ They move a lot of air and are reliable.
*by P***R on 29 April 2025*

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.
