Hi,
I am looking to upgrade the cheap builder installed exhaust fans in my
bathrooms. They are incredibly loud.
I can find lots of nice quiet ones, but they all required 4 inch (or
greater) ducts. The only 3 inch duct vents I can find are...cheap and
loud.

Does anyone know of a decent fan that will work with 3 inch ducts?

Thanks
Steven

One reason they are quieter is because of the larger ducts. That and
they generally also move more air.

I think you can get an adaptor that will connect the 4" to the 3". It will
make the fan a little louder than it should be, but if you buy a good
quality quiet fan it will be a lot quieter than the cheap one you have now.
Have you checked out the Panasonice "Whisper" fans? They're the wuietest
(and most energy efficient) on the market. They're expensive, but good. Good
luck.

bath exhaust fans are a bad idea anyway for a home...

in the winter they draw heated moist air outside,,,,instead... after
your shower, just open the inside door and keep that warm moist air in
your house..

in the summer, open a window...

if your using central AC in the summer, you are still better off
closing the AC vent in the bath and opening the window...

May be he is trying to remove the smell instead of moist warm air.

For the home as a whole, your comment makes some sense. However since
that warm moist air stuck in the smallest room in the house means mold and
mildew, they do make sense. Even your examples do not apply at all likely
combinations of conditions.

Use a 4 inch duct nothing less than 125cfm,s to make it worthwhile and
insulate the duct if you live where it snows

Yea I picked up an hard plastic adapter for a buck or two at the Borg.

When I got the fan, I noticed they had a noise rating on the boxes or
display.

Not sure I can buy into that one.


in the winter they draw heated moist air outside,,,,instead... after
your shower, just open the inside door and keep that warm moist air in
your house..

While higher humidity can make it feel warmer, that moisture in a tightly
insulated house can raise hell in various ways. In cold climates it can
contribute quite a bit to icing windows.


in the summer, open a window...

for quietest installation the fan goes in the attic and the intake
feeds to it from the bathroom.
see:Bathroom Exhaust Fans:
http://www.energyfederation.org/cons...hp/cPath/30_85
"A sone is a measure of loudness. The higher the sone rating the louder
the sound.
Understanding how loud an exhaust fan will be can be difficult, largely
because bathroom exhaust fans are measured in sones, while most common
noise levels we are familiar with are measured in decibels.
Scientifically, one sone equals 40 phons, which is the loudness of a
1,000 hertz tone at 0 decibels above our threshold hearing level. The
relationship between phons and decibels is not one-to-one (affected by,
for instance, frequency), but for our purposes we will assume that
decibels are roughly equivalent to phons. The chart below compares the
sound level of a sampling of exhaust fans with the sound level of a
number of other common sounds.
Sone

0.3
Panasonic 60 cfm FV05VQ2 Fan
0.5
30 Phons
0.5
Rustling Leaves
1.0
40 Phons
1.0
A Quiet Refrigerator
1.5
Panasonic 100 cfm FV11VQ2 Fan
2.0
50 Phons
2.0
Quiet Home
3.0
Panasonic 380 cfm FV40VQ3 Fan
3.0
Normal Office
4.0
60 Phons
4.0
Nornal Television Volume
Note that two sones are twice as loud as one sone, three sones are
twice as loud as two sones, four sones are twice as loud as three
sones, and so on."
