The fan has a 6" exit duct but our old house has 3" duct work going from our old bathroom fan to the attic. Can this fan be installed properly by connecting the 6" duct to the 3" duct?

Answer: 
Physically, yes it can be attached to a 3" duct, but that's a bad idea. This fan is rated to push 140 CFM through a 6" port, which is ~28 square inches in cross-sectional area. A 3" duct is about 7 square inches. So the fan will be trying to push air through a pipe that's one-fourth the size of of the 6" duct for which it's designed. This will do two things: 1) airflow (CFM) will be reduced (imagine Read More

This will do two things: 1) airflow (CFM) will be reduced (imagine yourself trying to blow air through a drinking straw vs. blowing air through a bigger pipe), and 2) the motor will be working harder than it should, which will ultimately shorten the life of the motor.
Install 6" ductwork, or buy a smaller fan designed for 3" or 4" ductwork. Read Less

No although some may try to tell you less.by using a reducer you are causing a bottle neck which results in back pressure. Eventually this causes undue strain on the fan motor and premature failure. At the very least, you will never attain the 140 from this fan is designed for.

Answer: 
You will have to reduce from 6" duct and match your duct. It can be done but you will lose(air flow) capacity as fan will be operating with higher back pressure. Short duct may not be to bad (5' to 10'). Longer lengths will increase the loss of air but still more than a smaller fan. It is critical to exit the fan and make any turns with 6" and then reduce to 4" or 3".

Answer: 
You could adapt it down to 3", but that will provide only 1/4 of the air flow in a 6" vent. Better than nothing, but it would function a lot better if you could run a 6" vent.

Answer: 
You can use reducer fittings to take the 6" outlet and step it down to 3". Personally, I was set up with an existing 4" duct connection I did not feel like changing out on the day when I was installing the new fan.
The biggest drawback to all of this is that the fan will be noisier than it would be with a larger duct.
You can reduce to 3" but it will not be as efficient as using a 6". It will still pull

You can reduce to 3" but it will not be as efficient as using a 6". It will still pull the moisture from the bath, it will just take a bit longer and be a lot noisier than it would be with a larger duct. Good luck!

My Home Depot had plenty of 6" components -- flexible ducts, ports, hose-clamps, etc. -- everything I needed for the installation I was doing, no problem.

Why does condensation collect and then dip from the fan

After someone takes a shower, there's condensation which collects on the plastic grids and then the water begins to drip. Doesn't seem right to have water collection around an electric item - is there a setting that needs to be adjusted?

Answer: 
Yes. I mounted mine vertically, no problem. If there's something in the product installation instructions that recommends against vertical installations, I didn't see it; but maybe you should check just to be safe. Mine's working fine vertically, super quiet, very pleased.

Rated 3.3 out of 5 by 38 reviewers.
Rated 5.0 out of 5.0 by Super Quiet We needed both quiet and plenty of air movement (CFM). This is by far the quietest bathroom exhaust fan I've bought or used, very pleased. Didn't even realize it was running the first time I turned it on, until I saw the exhaust damper move in response to the airflow. Seems to be a quality build, everything worked right out of the box (as it should!). Will buy again (my wife and I renovate homes), and gladly recommend to others. Note that it's exhaust port is 6" diameter, whereas many bathroom fans are 4" ports; so there's slightly higher cost for 6" ducting vs. 4" ducting, add'l clearance required to run the duct from the fan to the outside of the house, etc. August 30, 2016
Rated 5.0 out of 5.0 by Excellent fan This fan was installed during a bathroom remodel. It is extremely quiet, yet moves air very efficiently; installation was straightforward, and it worked exactly as expected. This is a great value if you only need a fan. August 2, 2016
Rated 1.0 out of 5.0 by Terrible product! 1. Fan sucks air out in the middle, but around the edges of the grate, it blows air back in the room. 2. Fan is VERY LOUD and has a rattling sound - we believe it to be the fan damper. Paid someone to install - now have to pay them again to remove and replace with one that works properly - will go to Lowe's this time. I will never buy a Hampton Bay - anything ever again! Probably made in China! April 6, 2016
Rated 2.0 out of 5.0 by difficult to install Don't buy this fan as a replacement. It requires you to disassemble the box in order to fit it into your ceiling hole and then reassemble it from the attic space. A really poor design from Hampton Bay. Instructions suck. March 14, 2016
Rated 5.0 out of 5.0 by Great Ceiling Bath Fan Originally I purchased exhaust fan for my master bathroom and it worked great. Decided to add another fan to my second bathroom. I have owned the first fan 1 1/2 years and the second for a few months. Although the fans are not totally quiet, they do the job. The noise of the fan is not extreme. The product is a great buy and recommend for anyone remodeling their bathroom. March 5, 2016
Rated 2.0 out of 5.0 by For new construction only While the very poorly written instructions don't say it, this is really only designed for new construction. You can not install this without attic access and if you cut the rough opening per the directions there is no room to attach the mounting brackets and slide it into the opening. Yet, if you don't install at least the small one before inserting into the opening, and you intend to attach directly to the side of one ceiling joist, you will not be able to attach this bracket in the attic. Very poor design. So you will have to bend the small sliding bracket flat, insert into the opening, and then bend it back out again above. And despite the instructions saying the brackets support 24" rafter spacing, they really don't. You can cobble together two longer brackets to do it but it's not a firm mount. And to make matters worse, if you cut a rough opening to the size the instructions specify so that no drywall repair will be necessary, you can mount the panel that holds the electrical box and 4" duct. You have to cut away enough drywall to get that to slide down, which leaves almost no drywall lip on one side. The fan itself is well built and quiet. But the installation is a disaster. I've installed enough bath fans in my day and this is by far the worst installation. January 22, 2013
Rated 5.0 out of 5.0 by Good Quality Fan A little heavy but it does the job well (remove heat & humidity) and not very noisy for a 140 cfm fan. It is quieter than 40 cfm fans I installed in another bathroom 35 years ago (still working as when new). Ceiling grille looks nice from inside bathroom. November 27, 2015
Rated 5.0 out of 5.0 by Great fan! I mounted this in an unfinished ceiling and framed around the fan to use the flanges as the mount rather than using the rails. The fan is not loud at all. It seems well built and the 6" venting helps move a lot of air. Time will tell if this thing holds up over the long haul. December 6, 2015
