Hey there, I'm looking for an exhaust fan for a 2'x5'x7' closet.. wondering if anyone has any recommendations? I've found a few online but I dont know how loud they are or if they're quality products. Thanks

If you have room I like this one

http://www.iaqsource.com/product.php?p=panasonic_fv-40nlf1&product=111092

they make many different cfm versions. The name is "panasonic whisper" and they are rated continuous run. You would want a remote install (attic/etc) they are fairly big, the only noise it makes is the air moving through the vent. Found this when my buddy showed me his new bathroom fan and it had 0 sound and was flowing 440 cfm.

FYI to compare these to the vortex fans, the sonne rating on the pannisonic for the 440 cfm model (which is actually 472cfm at static pressure) is 2.1 which is 36.4db in contrast the Vortex CFN-600 which is 449CFM runs at 49db. In other words its F'in quiet.

If you get a 6" 400+cfm inline fan and add a $20 speed controller (and decrease the speed a bit) it will be a bit more quite than getting a smaller inline fan if noise is a concern. It also gives you more control with fine-tuning temperatures in the closet.

Also, you can easily sound-dampen an inline fan since they internally cool themselves with the air they move.

Id go www.htgsupply.com here are a few that I looked at and ended up getting some of: GrowBright 4" Inline fan uses 80 watts and pushes 170 cfm flange size 4" $75.95.
GrowBright 8" Inline Fan uses 170 watts and pushes 590 cfm of air, flange size 8" $128.95 (I got this one)
GrowBright 10" Inline Fan uses 230 watts and pushes 790 cfm of air, flange size 10" $166.95 (I got this one too)
GrowBright 12" Inline Fan uses 295 watts and pushes 1050 cfm of air, flange size 12" $196.95
Also if your looking not to spend a whole lot of money I use to use an inline duct fan to do my friends closet that was 6'x6'x8' and we used inline duct fans which are way cheaper and do work on small spaces (not biger than 8'x8'x8') here a acouple from HTGSupply.com:
1)4" Inline Duct Fan 80cfm: $19.95 (Wouldnt use on anything bigger than 2'x2'x6')
2)6" Inline Duct Fan 160cfm: $24.95 (Wouldnt use on anything bigger than 4'x4'x8')
3)8" Inline Duct Fan 300cfm: $29.95 one I had and it worked well for what I needed (Wouldnt use on anything bigger than 8'x8'x8')
If you have money to spend then the GB Listed above or a squirrel cage fan are the way to go but if $ is an issue and your only venting a small space then the Inline Duct Fan are what Id get. Like I said I had the 8" 300cfm fan w/ 25' of ducting and we vented a closet that was 288cf 25' to his chimney and it keep the closet/smell/humidity the way we wanted it. Also the inline duct fans that come from HTGSupply are come with the plug installed, so all you have to do is plug it into your outlet or timer. I noticed the ones that are sold at Lowes or HomeDepot dont come w/ and plug and you have to wire them into your electric lines yourself.

If sound is your primary concern, check out the SP100 from Broan. CFMs are lower than the centrifugal models, but the sone rating can't be beat. Slap a switchbox/dimmer and an appliance cord on it and you're good to go. I use mine with a homemade carbon filter to take care of odor.

I noticed on the HTGSupply site they had a note that the inline duct fans were not compatible with Carbon filters? Why is this?

I understand the 250cfm 6" inline duct fan will only move ~175cfm if used by itself(not as a booster).. how is this any different from a 170cfm normal inline fan?

That's because some of the fans don't have enough suction power to pull air through a carbon filter bigger than it can handle, therefor making the fan AND filter useless.

The CFM rating vs. the actual CFM you achieve depends on how long your duct runs are, how many elbows you're using, added resistance from filters, etc. Flexible duct is really tough on airflow (friction), so you can get away with less CFM if you use rigid duct and try to plan a nice straight duct run. If you do things right, you should end up with a quiet and efficient system. Of course, if noise isn't an issue you could always just throw a high CFM fan at it. As far as the inline fan/carbon filter question goes, I'm pretty sure you can slap one on anything that's moving enough air. Maybe they're worried about charcoal dust in the motors or something. :bigjoint:
