Quieting a Vortex

Any tips on how to quiet a Vortex fan? I think it's a 465cfm. It's new out of the box and is very loud. Insulated ducting is probably the easy answer but even the intake is crazy-loud. It's an "inline fan" so would mounting it between duct hose quiet it as opposed to mounting the fan directly to a vent? BTW...this is for intake. I'm legal so stealth-ness isn't critical but sleep is. This bugga' is loud!

Thanks in advance.

Try placing some rubber (like tiretube) Between the mounting area and the unit .. then bolt it down ..Is it shaking ? humming .. whats it doing ?

It would be alot easier to switch that Vortex out with a TD Mixvent Fan from S&p

i think they are just loud in general dude. I have one on a fan controller + insulated duct + insulation around fan itself and it's still pretty audible.

I hung mine with nylon rope and its not bad on noise. Ive also seen people build a box around it, supposedly that hung with bungee cords is the best solution.

Thanks for the great replies. After dicking around with this thing since my OP, I agree.... it's just loud. I do have it hanging from bungeees and tomorrow I'll think about some sort of encapsulation...like a box as suggested above.

Seems to me the fan is internally cooled as the air rushes thru...so I don't have to be concerned about it getting hot or anything.....right? I was thinking maybe lining a box with styrofoam, think that would help?

Damn...it's loud. I wish I'd tried the brand mentioned above but it's too late now. It may see the hammer on Saturday.

Thanks again.

Don't use Stryrofoam... use eggcrate foam Google Image Result for http://www.foambed.com/merchant/images/eggcrate1.jpg

Another great reply. Thanks Potlike.

I ended up disconnecting the Vortex.

I also have a simiiar fan set-up on a scrubber. I was using the vortex to exhaust my (4) 430 hoods and the scrubber exhausts out of the room. So I disconected the vortex and exhaused the hoods into the scrubber. Will this damage the charcoal or is this an ok way to do this?

Shhhhh everyone look... 6" Duct Silencer - Fantech | this thing quiets the shit out of the fan. Product tested, grower approved.

Google "Bathroom fans."

There small, and quiet..
Just not sure about how much air they can shift.
