    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.

  • 349BR is rated 4.2 out of 5 by 16.
    Rated 5 out of 5 by from Product is well-engineered; durable; economical and, dependable! Purchased in June 2010 from Grainger through my employers' corporate discount program with them. Need was to ventillate attic space with goal to reduce cooling costs--performed above my expectations! Moved to new location and, re-installed this unit in this location. Runs virtually continuously for long periods of time, and, only gets a squirt of oil every year. This is probably one of the best $113.09 investments I have ever made in terms of return and cost-to-maintain. Quiet and trouble-free, also. Every residence should have these in their gable vent(s) where extreme high temperatures prevail. Quality products like Broan/NuTone don't really 'cost' in light of the 'values' they 'pay'/return.

    Rated 5 out of 5 by from the model is quiet working now and I cant really hear it. I had a electrician install the fan on the roof. Its seald and up and running I cant hear it , I hope this will hel cool down the attic in the hot humid days of summer. I selected Broan because of its name and reviews.

    Rated 4 out of 5 by from Great product Nice fan matched the color of my roof works fine turns on & off when needed, except I had to change the thermostat I added a humidistat to it. The other thing the location of the thermostat is under the fan so when it rains it splashes on the thermostat & rots faster, dont like that, I purchased this fan before, so I know, Broan should have a made better thermostat cover to protect the inner parts of the thermostat.

    Rated 2 out of 5 by from Makes alot of noise Great fan except it's incredibly noisy. When it's on you can hear it from any room in the house. It does pull alot of air and looks nice but it's a headache to have on. It's pretty dissappointing to go through the hassle of hiring an installer just for it to be so noisy. I'm overal not happy with the fan because of this one key defect.

    Rated 3 out of 5 by from Doesn't last as long as they used to Put 2 of these in in 1980. Both lasted till 2010 (30 years). Of the two, one stopped running at all and the other still ran OK but it had gotten noisy and the neighbor paid for a replacement. One of those I put in in 2010 has now failed (6 years). I don't know if it was just a bad one or if the manufacturing quality changed between 1980 and 2010. I suspect it did. I'm not sure any other brand would be any better as I suspect they are all now manufactured in cheap labor countries with marginal quality assurance and least expensive materials. So, I'll be ordering a new one of the same model so I can just replace the fan and control unit from inside the attic without having to muck around with roof shingles to replace the whole housing that I'd have to do with a different brand or model..

    Rated 4 out of 5 by from 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!

    Rated 5 out of 5 by from works like a charm! bought this to reduce the temp in the storage space above my garage, does what i wanted it to do!

  • Thermostatically controlled

    Does this fan have a thermostat so it will come on automatically? Is that is what is considered other controls?
    Asked by: Mike
    Thank you for your inquiry. You might be hearing a back draft damper that is being affected by over pressurization of your house on a windy day. It would help us to know the model number of your product which can be found above the grille on the ceiling. If you cannot remove the grille, contact us in the Technical Service Department at 1-800-637-1453 for further assistance with your questions. We'll be happy to assist you.

    I am going to replace my exisiting solar attic fan # 3555SO with an electric fan. Can I swap the fans and install in the existing fan housing?

    Asked by: Chops
    Thank you for your question on the model 356BK. The solar and the electric attic fan lines are totally different sizes and parts are not interchangeable. Please feel free to contact the Technical Service department at 1-800-637-1453 with more questions.

    Thermostat backwards?

    I just installed the 35316. It's 68 degrees in the attic. I set the thermostat to 70 degrees, and it does not come on. Good. I set it to 80 degrees and it comes on. Same thing for anything higher than 80, it stays on, even though the attic temperature still at 68. I expect it would not turn on at all until the temp rises. Is this a defective unit or am I misunderstanding this? Thanks.
    Asked by: JPJ
    My unit has performed in the temperature range on the unit. Attics get very hot quickly in my geography--the power used by my model Broan is roughly equivalent to a 100 watt (or less) light bulb, I've been told.

    15 amp breaker

    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?

    Thank you for your question on the model 353 gable mounted attic exhaust fan. From your description it sounds like a wiring problem or defective unit. Please contact the Technical Service Department at 800-637-1453 for assistance.

    If a model 353 vent fan is mounted on the underside of a roof will it still perform well?

    Asked by: The bass man 57
    Probably-but be sure the exhaust side you want is positioned to either draw out or in....
