  • QT140E is rated 4.8 out of 5 by 24.
    Rated 5 out of 5 by from Broan Exhaust Fan We had a bathroom fan that was too small for the space so upgrading to this unit has been great. We have had It over four months now. It eliminates any humidity while in the shower so no foggy mirrors or condensation on the walls. Due to the location in the attic we used the 4 inch exhaust line but 6 inch would have been better. We did have a few drops of condensation drop from fan on very cold days but using a portable heater while in the bathroom has eliminated that. Very quiet and well worth the investment!

    Rated 5 out of 5 by from large bathroom vent I wish my builder had installed this vent in our bathroom. Moves a lot of air using a 4" roof vent. Very quiet and an excellent value.

    Rated 5 out of 5 by from Powerful Great Product ! We were getting water marks down our walls because of long steamy showers. We thought we would have to repaint after only 18 months. Some one told us we should try wiping the walls down with a white rag and water and then install a more powerful fan. We did just that and have not had a problem since. I highly recommend this product!

    Rated 5 out of 5 by from Past Experience Chose Broan Again When remodeling our Master Bath there was no question which fan we wanted installed. We used Broan in our last home and they always worked as advertised. So when we needed one in our new home, we never looked at another product. The quietness and air movement are as advertised. Extremely pleased with the product.

  • Detail on installing flap into the Duct Connector - 6” would be helpful.

    1) If my roof cap has a built-in damper, do I need the flap in the Duct Connector? 2) Assuming that I do need the flap, then more help in installing the flap would be nice. Here is where I am confused: Looking through the 6 inch round connector as it goes into the rectangular shape to attach to the fan, the top of the rectangle has a "foam strip" glued to it. If I insert the flap with its top in front of the foam, then the flap will be restricted from fully opening, but the flap will close completely (see picture "flap top in front ..."). If I insert the flap with its top behind the foam, then the flap won't close, but can open fully (see picture "flap top behind..."). Please let me know which is the correct installation. It seems to me that the "foam strip" should be positioned more towards the front, so that the top of the flap can be behind it, which would allow the flap to both fully open and close. There are no details given on this part of the installation. I feel that this is important information, because the tabs on the flap seem weak and will only tolerate so many attempts at installing it correctly. Also, I believe that I have the orientation of both parts correct, but it would be nice to have confirmation.
    Asked by: jrfiedler
    The question is great and the photos are helpful. I am having the same issue and need some clarity. Unfortunately, I am not sure if the answer given by the manufacturer was foam in front or foam behind as you describe it. The bending answer they gave was confusing because I don't want a restriction but it would be nice to have a nice seal in the winter. Can you guys answer in the context that the question was asked? Flap top in front of the foam or flap top behind the foam???
