SuncourtInductor Inline Duct Fan, 6 Inch Diameter

Works great not too loud. Very easy to install with some know how. I have it mounted vertical and it moves a good amount of air. Update: I just bought another one and it is running just as smoothly as the first one. FYI I am running these using a fan controller. Works great!

We used this to exhaust hot air from our server room. We ducted all the server hot air into a 6" pipe and then used this fan to send it through the roof. Works pretty good. It's not terribly loud (quieter than the 6 servers hooked up to it. Seems to do a good job. We'll see how long it lasts. Was nice that the unit comes pre-wired with standard 3 prong cord. They have others that do not (if you prefer or need to wire yourself)

First one lasted a year ok motors aren't great. 2nd one last 2 months I'll try a different company for the 3rd. They wouldn't send me another one since it lasted a month

This was a sheapo fan that doesn't move much air. These usually last 4 or 5 years in my application where they run 24/7/365 but this one only lasted abt 18 months. Spend a little more and buy better quality

Quite a bit louder then I expected. I used this fan to boost the airflow into my living room as the duct to this end of the house has a long way to go with many bends. I used this fan and a duct stat and when it turns on it sounds like a train is going through the house. Unimpressed and will be uninstalling it today, one day after I put it in.

For the price this is an exceptional duct fan that is well made, quiet, and powerful.

I use this to distribute wood stove heat through ducting in my house and ti works great and not very noisy, not more than any other fan.

Not sure if it is installation error by the HVAC Tech or manufacturing issues, but this fan is LOUD! Only been installed a few hours and im having to tape and rig up a way so the buzzing doesn’t drive me nuts.
