  • 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.

  • 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.

    Are 3D models available to the public for this Attic fan?

    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.

    I just replaced the motor on my 355F unit, rewiring the same way I removed the old. Now the fan does come on. I have thermostat set for 90 and its well over that today. All was working prior to replacement and the new motor was tested prior to installation.

    The fans ( I have 2 ) run continuously and I would like to change the setting so that they will shut off during the cooler night time periods.

    Answer: 
    Thank you for your question on the model 350BR roof mounted attic fans. The thermostat would be accessed from the attic side. It should be mounted within approximately three feet of the fan itself. The thermostat will be adjusted with a small flat blade screwdriver.
