  • Roof matching domes means ventilation is less noticeable.

    Too often, attic ventilation is overlooked, not to mention ignored as a place for energy savings. That’s where Broan solutions make sense. Consider this: air trapped in your attic can easily reach 150 degrees or more. With Broan ventilation solutions, it’s still a full 60 degrees cooler in the attic on a 90 degree day. That’s why attic ventilation is critical to making any home more comfortable while lowering energy costs. Air conditioners can run less and won’t have to work as hard. Humid, stagnant air can be removed, drawing fresh dry air across the surfaces. Your attic can be drier and cooler – the perfect tools to help fight potential moisture damage.

    Each PVC dome is available in three popular performance ratings along with two metal dome models. Select one that best suits the attic size and shingle color.

    Solar Options For Your Attic Ventilation

    Solar Powered Attic Ventilation - Pittsburgh Today - Live KDKA TV

  • Effective attic ventilation requires air to exit at or near the peak of the roof and replacement air to be drawn in under the eaves of the house, via soffit venting. The Home Ventilating Institute (HVI) recommends that powered attic ventilators provide at least 10 air changes per hour to equalize attic temperature.

  • Rated 4.4 out of 5 by 10 reviewers.
    Rated 4 out of 5 by Great job for about 8 years My fan died after about 8 years. Other than that it worked just fine. Could not be more pleased, all motors die sooner or later. Considering the extreme attic temperatures I was surprised it lasted over 4 years. For the price at Lowe’s you can’t beat it. Off to get another one! May 30, 2016
    Rated 5 out of 5 by product name replaced old fan 25 + years old so far so good works as expected if it lasts 25 years I will be happy September 5, 2014
    Rated 5 out of 5 by Powerful enough to get the job done! Bought this as a exact replacement. We live in the south and an attic fan is a must! We have a 6 in 12 pitch roof, plenty of draw space for this fan. This house does not have gable end vents but has properly vented soffits and vinyl clad porch ceilings. It gets plenty of cool air pulled into the attic. BE SURE TO HAVE UNBLOCKED VENTING for this fan! It has made a huge differance in the a/c bill. This is a very powerful exhaust fan (8 amp motor) and it will be a little noisy. You get used to it. There are days in the upper 90's that it will run 12 hours or more. I have it set at about 110 to 115 degrees. The instructions will tell you that it cools to 10 degrees below the starting temp before it turns off. Be sure not to have it set to low. Think about it, if your outside temp does not cool down in the evenings it will continue to run to reach this 10 degrees below start temp. The attics can get brutal here in the south. I made the mistake of setting the temp to low on my first setting of the thermastat and had to re visit the attic to adjust it up some. I would suggest that you put it on a switch up in the attic close to the installation point of the fan. It sure does make it easy to service or replace in the future. It was a perfect fit into the existing casement for the old one. Did not have to remove the fan housing from the roof. Sure it was a little rough working with it above your head in the attic standing on the trusses but it was very do-able. I read on a couple of the reviews that it can be replaced from the outside of the roof also by removing the top cover if your screws aren't to badly rusted. You still may find yourself in the attic to hook up the wiring. IT IS NOISY! GET USED TO IT. It is to be expected with this type of a fan. It totally out ways the benifits of what this will do for your cooling bill! I believe our attic is about 2300 square feet and is properly insulated and the soffit vents are not blocked by any insulation. With that being said there is only one of these needed in our attic. If the noise is a concern I would suggest you check into a gable end attic fan. Most of the time they are larger and quieter. As for the life expectancy of this fan I can not yet say ( the original one was burnt out when we purchased this house), I have had this one in for 3 months now. I would highly recommend this fan!

    Rated 4 out of 5 by 35316 works as designed I purchased a house where the two old gable fans no longer were operational. I found the 35316 on-line at Amazon.com and ordered two fans. My contractor installed them with light switches so I could manually turn them off without using the built-in thermostats. As it turns out, one of the fans failed to work when I turned it on. The contractor checked that there was power to the fan. I called Broan and they immediately sent me a new thermostat and motor. As it turned out, the original motor was defective - DOA, but the thermostat was OK. I unbolted the fan from the housing and disconnected the wiring and installed the replacement motor into the housing and reconnected the wiring. The customer service person was very helpful telling me that I needed about 4 square feet venting/fan for each fan to operate properly and that I should set the thermostat to about 30 degrees above the normal room temperature for each attic. This was very useful since the fan that was working was on all the time because I set the thermostat temperature too low at 80 degrees causing the fan to stay on all the time. Broan makes good stuff! My stove top exhaust fan is still in perfect condition after 50 years of service. I highly recommend Broan for the quality of their products and honoring their warranties. July 20, 2014
    Rated 5 out of 5 by The attic fan has great features The instructions are helpful and make for an enjoyable install. I am wiring in the thermostat bypass and fan motor switches. I am looking forward to the first summer with an attic fan and expecting the house to be more comfortable. April 29, 2014
    Rated 1 out of 5 by The 35316 exhibits a horrible vibration that shakes the entire house. Great potential if only the fan was balanced at the factory. Vibration is horrible. April 23, 2014
    Rated 5 out of 5 by Easy to install and relatively quiet This power ventilator is rather easy to install on a cool day. A cool day is easier on the installer and on the shingles. This ventilator was installed in the early spring with the temperature setting on about 100. As a consequence, it did not operate until several months later. One evening I noted a noise on the roof and sure enough the power ventilator was operating as it should. Later in the evening it was OFF. As it is now March 2014, the unit is OFF and very quiet. March 13, 2014
    Rated 5 out of 5 by Much Improved Product This model replaced an older Broan ventilator installed around 15 years ago. This newer model is much quieter, has a better thermostat adjustment and is definitely more efficient. March 10, 2014

    We have sealed and conditioned attic that I want to ventilate periodically using a switch or timer. The attic stays cool so the thermostat would likely not cause it to come on often.

    Maintenance for 356-G?

    Customer avatar

    matlinp

     on 356BK
    I have a 356-G attic fan which was installed a number of years ago. I'm now detecting a strange noise from that area of the attic - like power is being applied to the fan, but nothing is moving. This lasts for maybe 10 seconds, dying out over the duration of the incident. Recurs every 5-10 minutes, when the fan is off. I haven't as yet climbed up into the attic, but I don't see any information concerning maintenance in the installation manual. I'm sure that there is dust buildup over time, etc. What are the recommended user maintenance procedures, if any?

    Answer: 
    Thank you for your question on the model 353 gable mounted attic ventilator. The setting of 105 degrees is our standard recommendation. You can always change the desired setting and see how it works out for you. It is not unusual to have long run times in the summer months.
