    Solar Options For Your Attic Ventilation

  • 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 5 out of 5 by Nice product I would use this seller again. excellent service. fast shipping. November 1, 2014
    Rated 5 out of 5 by Broan 358 attic fan. Great product I ordered this attic fan in August. I had a new roof put on and the roofers installed it for me. I am very pleased with the job it does pulling the hot air out of the attic. A friend told me about the attic fans, i am sorry i didn't put one in sooner. September 12, 2014
    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 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

    I just installed this Gable fan in my garage and it keeps tripping my breaker. This is rated for 3.4 amps and there is only 1 light on the same line which is an LED light.

    The fan was running for several hours before it tripped the breaker. Now it trips the breaker the second it starts.

    I'm wondering if it could be a bad motor causing it to pull to much and tripping the breaker.

    Has anyone else had this issue?

    Answer: 
    After doing a little more research and testing it turns out the fan was pulling too much current and causing the breaker to trip. Once replaced the item works great.

    I am trying to design a scale model of a secondary garage for a customer and would like the "true" model of this exhaust fan since I am choosing it for his build. Does a 3D model exist for this version? I downloaded the model catalog available on the website and could not find this attic fan as one of the options in there.

    Answer: 
    Thank you for your question on attic fans. A bad thermostat could either keep the fan running at all times or it could keep the fan from running at all. The adjustable thermostat would be part number 97008413 and you can get it through the “Shop for Parts” link at the top of our web site page. It should be pretty easy to replace.
