I have to admit, when I was shopping for a power fan to vent my xTool P2 laser engraver, I was a little worried about power (would this fan give me enough?) and loudness levels (would it be too loud?) and I have to say, it's perfect on all accounts.
My system is probably just as complex as you'd guess: xTool P2 Laser, connected to a xTool filtration system, and then vented outside. That's three ducts (printer to filter, filter to fan, fan to outside) at 4", and the P2 itself is natively 3", but I bought an adapter on-line to make it 4".
So overall, the fan works great, like wow! You can still hear it - it's not super quiet, but it's also not annoying. It's more of a louder "whoosh" than an annoying whine, if that makes any sense? And that's me running this fan at full-power, which is basically where I'm going to keep it at. It's possible that your needs won't be 100% all the time, and it is absolutely quieter at the slower speeds.
The duct connections are perfect, and the 6" to 4" adapters I purchased here on Amazon were absolutely flawless and leak-free.
As someone who buys a lot of high-end computer components, one of the things I really appreciated about all of the AC Infinity products (three ducts and this fan) is that it's well packaged, with a lot of accessories. It's almost like opening an iPhone, if iPhones came in dark packaging.
It's also clear what this fan was designed for, as it came with a "how to grow hemp" manual, which made me laugh.
There's a nice YouTube video on-line that explains how to set this all up specifically with the P2 (with details on the 4" to 6" leak-free custom adapters), and he tells you to get this model, and not the one that has all the bells and whistles (Bluetooth, WiFi, garbage disposal, toothbrush). I'm glad I got this exact model (S6 PRO).
The remote is cool, and comes with a nice LONG (9') cable so you can put this wherever you want. You press the button once to turn it on, and it remembers the last settings (1-10) if you hold the power button for four seconds to turn it off. It's pretty cool!
I love the design, and the fact that you can remove the center blower, to install the bracket on the wall, and then put the blower back in. Solid build quality.
Overall, I'm very happy with this blower fan, and would absolutely recommend it for hydroponics and exhaust systems.

So far I am pleased the fan, which is very quiet. Most of the noise is air rushing up inside the hood.
