Rated 4 out of
very good fan nice and quiet
I agree with the other ratings except with mine when its windy the flap on the fan outlet bounces (and raps the side) with the wind. I'm going to take it apart to see if i missed something when I installed it.

XB80 Very Quiet
The contractor installed this XB80 Model without any issues. He used 6 inch solid metal duct. This unit is so quiet it can barely be heard. It looks nice, and works very well. Would highly recommend to others!

This product does a good job of removing steam/moisture from the bathroom
I would definitely recommend this product. It efficiently removes steam and moisture from the bathroom it is less noisy than my previous, less expensive fan, but not as quiet as I expected. There is a slight delay from turning on the fan to when it actually starts up, but doesn't affect its overall performance. I had someone install this for me and he didn't seem to have any difficulty with installation. Overall a good product for the money.

Not as easy to install as advertised
I will bet if you had 16 inch center rafters it would be as easy as advertised. I have 20 inch center rafters and it was much easier to install in the attic. Also, I needed to purchase a 4-6 inch HVAC adapter to hook into existing 4 inch duct. Oh and by the way HVAC foil tape will not stick to the included 6 inch duct adapter. I had to use a bunch of the best duct tape from Lowes and a lot of it to ensure no leaks in the future.

Is this fan rated to be operated via a rheostat?
Use the ZB series (ZB80 and ZB110) for rheostat controlled fans.

Are the motors brushless ,
Would like to use in a hobby paint booth , what type of
Motor,, brushless ??
I'm thinking it would have to be brushless or there would be maintenance parts. It is probably induction. One thing for sure, it is quiet.

I have an 80 CFM fan with 4" ducting. I noticed the soffit vent I chose is only 3.5" at the opening. Will this significantly degrade performance of the fan?
Yes, it could decrease the performance of the fan and increase the noise. Please contact our technical support department directly for further discussion at 1-800-637-1453. They are available Monday through Friday, 7:30 am until 6:00 pm CST.

If I must use a 3" duct
My bathroom fan sits atop a radiation damper with a very short run
to the roof, perhaps 24". The roof is only a foot over the ceiling. I have not removed the old fan/damper yet,
but I have bought the XB80 and an RDF1. If I use a 6" to 3" reducer
what would be the harm? A little less airflow I can live with. If the
motor is going to burn up quickly, well then, what would you suggest?
I'm really hoping the very short exhaust run will allow me to use this
awesome fan. Dale.
The XB80 is recommended to be installed on 6” duct. If this is not possible, the 6” to 4” reducer may be used. For reasons of excessive noise, reduced cfm (cubic feet per minute) and potential harm to the motor, using 3” duct is not recommended, even considering your short duct run.

I installed the XB80 in a 1st floor powder room & used the 6" to 4" duct reducer. I had to reduce further to 3" to meet the hard duct.
The 3" hard duct runs horizontally through the joist space on the 1st floor then vertically up in the wall stud space into the attic. In the attic I expanded from 3" to 6" in order to hook up to a 6" roof cap. Will my duct work hamper or damage the XB80 fan?
Thank you for your question on the model XB80 exhaust fan. The XB80 was designed to use six inch duct work or possibly four inch (using the six inch to four inch reducer), but you cannot reduce the duct work to anything smaller than four inch. With the installation you are describing, the fan will be mostly ineffective.
