HVAC bathroom exhaust fan routed to return air duct?
Oct 23, 2008 by thebinaryboi | Posted in Maintenance & Repairs
For HVAC experts.....I have never seen this before: a bathroom ceiling exhaust fan which is routed to the return air duct in the attic. Is this a code violation? If not, is there any problem with ducting a bathroom exhaust fan into the return air duct to the furnace? Seems odd to me.
NO NO NO NO, The Bathroom should be vented only to the outside. This air is HOT and Humid. Should Not be connected to the duct work at all. Quick fix, take the fan loose from the duct and let it go into the attic, until better weather, and get a piece of insulation and tape up the hole.
When weather turns nice route the vent to the outside. Keeping the run as short as possible.

Im not sure if it is a code violation, but it is different. I work for an air duct cleaning company, and we price bathroom exhausts seperate from other vents because they are not associated really with the normal vents. Sorry I dont really have an answer, but I figured I would throw something out there!

Most forced air ductwork's have a humidifier built in to add moisture, but it is usually only activated in the dry winter months to control static electricity in the home. Having an exhaust bath fan hooked up to a furnace sounds like a homeowner mistake, not done by a pro. Moisture would be blown into the non-operating furnace during the months when the furnace is not on, causing moisture related problems inside the blower/plenum, possibly mold or rust.

The exhaust should be vented directly to the atmosphere. usually using flexible dryer type vent.Attach it to the exhaust on the unit and lay it parallel stretching it out a couple of feet.

would my bath exhaust ducting be adversely affected if I doubled the RPM's of my fan motor?
Oct 17, 2007 by DannyBoy | Posted in Maintenance & Repairs
current exhausting is very poor with 1550 RPM motor. (approx. 90 CFM)
You should get a new vent fan rather than swapping out the motor in your existing one -- if that's what you're suggesting.
As far as the duct work is concerned, just check the requirements on the new vent.

HELP ME?? NEIGHBOUR DISPUTE- noisy exhaust fan ...?
Jan 13, 2007 by MOZ | Posted in Law & Ethics
I have just purchased an apartment in western sydney. I've done various inspections but none at night. Last night i went over to show my folks the place i'd bought when i heard the whole roof vibrating. It is caused by an exhaust fan on my roof from the chinese restaurant down stairs which only operates at night.
I'm afraid i'll have trouble keeping tennants with this noise... does anyone out there know how to handle this problem legally in australia??? I want to know as much as i can before i approach the body corporate and the owner of the restaurant. Any help would be appreciated.
PS. the fan and ducting are installed in a sub standard way where the duct is sitting directly on the roof tiles and the fan has someserious shaking going on.
EPA is the answer......
no matter if it is littering, smoke or noise polution.... they 'll investigate..... every hazardous situation......
open your phone catalog ....they must be somewhere in the front pages....
the number is a 1800 number

Exhaust setup Can you use an inline fan as an exhaust blower?
Nov 27, 2008 by Amy M | Posted in Do It Yourself (DIY)
Can an inline fan be mounted to basically hug the wall (or as close as it can be) so that it is the *exhaust blower* without there being a "line", with out their being any ducting on the other side of it? And if so, instead of it hugging a solid wall, what would that be called that makes the fan connect to the hole in the wall. The grill? or the register? or flange? or whatever?
Yes, you could use an inline fan as a thru-the-wall fan, however if you are venting over a stove or venting flammable solvent/fumes, the fan would need to be a sealed, explosion proof unit.
Mounting flanges would need to be attached in some fashion, along with some type of protective grill that would prevent fingers/hands or other things reaching the fan. Same would be necessary for the outside & probably some type of outside cover that would close when not in use.
Good luck...
