Quietiest in-line fan on the market??

Well what brand/model # is it??

certainly not vivosun, thats for sure

I've heard good things about the vortex s line series. If you use a fan controller don't cheap out on it, the lower quality models make the fans hum. Get a variac controller or something similar.

Bought a vortex "s" line and found it cheaply made and way loud ...sent it back and bought a "Soler & Palau" silent line and have been very happy.

Both my Hyper Fans are very quiet. Very happy with them.
Just my .02
WE

10 inch Hyper on 35-50%

Sun Leaves Wind Tunnel 6" is what I use and it's awesome.

Hyper Fan “Stealth”. Amazing fans

Just ordered the ac infinity 6” model with thermostat control. 32db low somewhere around though there is a video on full at 56db

Price I paid was main factor at $98 with card rebates etc.

Just tried putting link new account won’t allow too new.
Ac infinity cloud line t6 name of it

max fan, q max pro, comes pre built inside a muffler

Hyperfan stealth another great alternative to the can fan q max pro as some have mentioned.

Hyperfan typically a bit cheaper if it matters. I litterally just went through this issue trying to find something if not for price would have gone with hyperfan. Also can always make your own muffler for fan if needed.

Rambridge in-line fans. Quite and mine is on its 16th year!

Would a good (thicker) tent knock down a few of the decibles???

Most likely not

Yes it would certainly help, but given the material it could be very feeble improvement. There are special thick sound damping cloths you could make like a cover for your tent from, I guess. But that calls for sewing or other innovative ideas.

You can quiet your fan by making a box for it and/or putting fan muffler tubing on both sides- inhale and exhale of the fan. There are many pretty easy ways of making that with egg foam. If you can, use insulated hose ducting. Note that except the box, all the solutions reduce airflow.
I would also consider some dust filters on all intakes. You really wanna the cleanest air coming in your garden.

Hope this helps.

It’s not the cheapest but isomax fans are pretty good

I have an isomax, formerly airforce2. They are powerful and good fans. The issue I have with them is they come with a built in electronic speed controller, although the manufacturers stated you can turn it to full and hook up a variac speed controller they do have a little hum.
I have had mine on for nearly 8 years 24hours a day. So they are a quality fan.


Here is a fan test of the S and P td silent, if you look at all their vids they test all major branded fans.

At the end of the day the best option is to buy a big fan and have it run low speed using a variable transformer.
