Considering the noise is my number 1 preoccupation which one would you say makes less noise?
thx

vortex its loud but u can do something about that
buy a speed controller
make a sound proof box, what i did was just take so insolation n wraped it around my fan then covered it with a trash bag
make duct mufflers
now u can hardly hear my fan only when the door to my closet is open and it quieter than my celling fan

Ive heard somewhere that speed controllers are dangerous but cant remember why

any others out there have a problem with 6inch vortex's veing too loud?
any pics of rigs to solve the problem?
tis a bit loud for me and i dont have much room to make mufflers nor can i remotely mount er.
so its muffler er or send er back and i LOVE it and WANT it to work for me.....

I recently installed a 6" Vortex and while it is somewhat loud (strong whoosing sound with a hint of jet engine) hanging it from bungees and using insulated 6" ducting has made it pretty quiet. Im sure a speed controller would help even more but I dont use one.
little-soldier - Ive seen that using controllers not designed for fans like this can be dangerous but the controllers specifically for the Vortex are safe.

Solid state speed controllers MUST be used with inline fans. DO NOT use a dimmer type switch. Vortex 6" fans do have that jet engine noise as they are moving 447 cfm through basically the same housing an Elicent 6" 309 cfm fan and obviously the Elicent is quieter...even though I think Elicents are better overall in quality. Having the intake or exhaust opening close to the fan housing increases noise. Use oversize ducting wherever possible as will help some. Putting a 360 turn in the ducting will dramatically kill noise but also airflow so you'd have to use oversize ducting and an oversized fan. Using insulated ducting helps noise transmission also...and yes using an oversized fan running on oversized ducting and dialing it down with the proper fan speed controller helps big time BUT I've noticed there's an entirely different whine that can happen when you run a fan at a reduced rating. Running a fan less than 50% of its rated volume is not advised. I've wrapped fans in all kinds of stuff and it helps but not too much.
Weigh the options.

Adverse,
Did you mean that fan speed controllers must be used or just that *if* you use a controller to use the ones designed for the inlines? I dont use a controller at all and let it go full blast for maximum summer cooling. Is there something Im missing?

IF you decide to use a controller it must be solid state.ItsGrowTime said:
That's bullshit cause I own both.

i am using a 6" canon i got from justin @ hidhut. i just mounted it directly to my ceiling and hooked my ducting from lamp to fan. i obviously am going to work out something for the noise, because its extremely noticeable outside the room (sounds just like a bathroom heat exhaust fan when standing outside a bathroom with it on.)
i had thought about a speed controller - and may still end up purchasing one. however, my first option is going to build a muffler box around the fan - hoping that it will reduce the noise enough. we dont have to hide it from anyone living here, but we dont need guest wondering wtf we got going on behind that locked door either
ill be following to see what you do, and i can post pics of what i end up making. here is a shot of the current setup.

No offense Bearfootlove. I've currently got 11 different inline fans going, mostly Elicent, a bunch of Vortex and a few Groteks, and know what each sounds like. Don't believe everything a manufacturer tells you :wink:.

My speed controller lowers the CFM's, but not the sound by much...
Still whooshing through feet and feet of ducting...
(2) 4" vortex - One on low, one on High, all times.
Just don't want anyone thinking a speed controller is a magical solution.
It's not.

That's also my experience. I've messed around with controllers on different cfm fans from different manufacturers for the last couple of years. Fans love to run at full speed.

Just read this...I built a cardboard box and filled it with acoustical foam, used a 6" elbow pointed at the foam and offset the other opening at the top of the box. I used an 8" stove pipe with kind of cheapo 1" foam inside and 2 8" to 6" reducers. The stovepipe setup sat on top of the cardboard box. It totally killed the jet engine noise from the 6" Vortex down in the basement that was coming through the intake ducting in the closet but it still did not stop the whooshing noise of the air and my guess is I would need to use a 10" stove pipe and 2 10" to 8" reducers. The remaining noise is now coming from the 447 cfm trying to get through the 6" opening.
Anyway...

hmmm. im going to try a few things with mine (probably this evening) since its just noisey enough to be noticeable... and noisey enough to be a nuisance at night (which could be shut off at night for now but want it operating quietly so when i have to kick it on during summer nights.)
ill post pics and discuss things that worked and things that didnt

so im back with results from what i did - and it was very effective, at least for me and my situation. also want to say - i know the original question was regarding which fan to get... however you are going to have noise with pretty much any fan running with this much power. my 6" cannon is only rated at 250 CFM and it's still loud. i bought it because it seemed powerful enough for my needs, yet not a monster like many of the other fans (just didnt feel i needed 400+) and im pleased now with the outcome.
so... i did 3 things.
1) moved the fan out of the grow room (being mounted on the wall and directly attached to the ceiling was causing more vibration - and so... more noise. i kicked open the attic crawl space and moved the fan above the room. this killed about 15% of the noise
it looked like this before:
2) i used bungie to suspend the fan from the rafters in the attic. i figured if the fan being mounted directly on the wall was causing more vibrational noise than just the fan housing itself... why not suspend it. this also eleminated about 15% of the noise
here is a pic
3) and the most helpful was the muffler i made. before i decided to mount it in the attic, i also wanted to see how the muffler worked. i dismounted the fan from the wall and propped it up on the floor... connected the muffler and was very happy with the result. if i was only going to change one thing - it would be to add the muffler (which was easy to make, and cost about $30 in parts)
here is a picture of the muffler after all the attic work is done. i can post a DIY on the simple build if interested. this helped reduce the noise by 40% on it's own!
all together i've reduced the noise of my fan by 70%... way more than i had hoped. i hope this helps you too. peace

i've got a 250cfm panasonic whisper inline fan and it is very quiet. the only noise, like most other high cfm fans is the woosh of the air passing through. a carbon filter on the exit side will help dampen the noise a little bit

i dunno what model it is, except for it was cheap and got the job done. It took some engineering to get it all the way it is. Cab is 20" deep and i think like 5' wide and 6' tall. My only complaint is that it is such a huge cab which makes it immobile, but it doesn't look like what it really is....
