I want to quiet down my 8" can fan. I've seen several different mufflers for sale but do they really quiet down the noise?

Do mufflers actually work?

Vortex is making a quite fan now as well. Its still fairly extensive com paired to its cfm tho.
Booster fans will run quieter as well
Booster fans will run quieter as well
Hell yeah they work an they connect after ur fan....not on the end.
seems like they change the tone or pitch of the fan to me. but it is called a muffler and not a silencer for a reason
It's a MaxFan from CanFan if I'm correct.
I wouldn't recommend using booster fans over inline centrifugals as they don't handle static pressure well at all.
Use a muffler at the end of the ducting to lessen the noise of air dumping out of the ducting.
Build an acoustic fan box to place the fan in,this will cut down on the noise of the fan motor itself.
Use oversize insulated ducting,this helps cut down on the sound of the air wooshing around in the ducting,and since it's oversized it will allow for better airflow.

Silencers are a waste of cash IMHO
Insulated ducting is quite effective, noise wise and heat management! Peace babeh
um no they go on after ur fan to silence the FAN. Look up the instructions on a bought silencer/muff. Im looking at mine an the install directions from phresh filters reccomends u connect to straight to the fan.
I would be very cautious leading with "um no." and using caps to emphasize a point unless you are POSITIVE that you are right.
It is to control the air noise. The air coming from the exhaust side of the fan. It doesnt matter if you connect it to the exhaust itself or to ducting that is connected to the exhaust itself.
Ask yourself how a duct muffler works. Think about its design. Take a look at one. Put it on the running fan, then take it off. Note the difference.
Ask yourself what is going on that makes a difference in noise.
Look up the word "muffler"
If you're still sure, let me know how it works to control the noise of the actual fan.
I have tried a few and they work great. I like the one in the second pic best. Peace GS

Um no, Um no, Um no
Um no, Um no, Um no
try it lmfao......
do you want a whole duct run hummin or take care of the noise an turbulence at the source. Im not sayin the fan wont make noise itself, thats another beast to tame with a sound box of sorts.

You funny guy, you make-a me laugh-a.

You can install it on the fan and thay will cut down on noise,but not the actual fan motor noise,just the initial wooshing sound of air.The only way to cut down or completely cut out the fan motor noise it self is to build an acoustical fan box and place the fan in said box.
Most people when reffering to noise associated with an exhaust fan are talking about the sound of air rushing around inside ducting.
IMHO the best things to do to cut down/eliminate all noises are
1)Build an acoustical fan box to place the fan in.
2)Use straight smooth (pipe style) ducting before and after the fan (rigid ducting makes for more noise as it is not a smooth surface).
3) Use oversized insulated ducting.Since it's oversized,the air will flow more freely due to less pressure losses thus making the fan work more efficiently.
4) Use a speed controler on an oversized fans...for the most part,the bigger the fan,the less rpm's.
5) Use of a duct muffler.

Agreed.
