Surface Mount Solar Powered Attic Ventilators

Broan® 537 CFM Solar Powered Attic and Garage Ventilation Fan, Surface Mount, Weathered Wood

Prevent heat and moisture build-up with the Broan® 345SOWW Solar Powered Attic/Garage Ventilation Fan.  Attics can reach over 150°F in summer, warming your living area, increasing the air-conditioning load and your energy bill. In winter, ice dams can form, and moist air can condense causing mildew, rotting wood and wet insulation. Year-round attic ventilation ensures a cooler, drier attic which can extend the life of your roof and air conditioner, while lowering air conditioning expense.   Besides the attic, this ventilation fan is also designed for one and two car garages.  Say goodbye to unbearable heat, humidity and unwanted smells that accumulate in the garage.  The Broan® 345SOBK Solar Powered Attic/Garage Ventilation Fan uses energy from the sun to operate and requires no additional electricity, which means you save up to $180 per year that you might pay to operate an electric powered attic and garage ventilation fan, depending on your local electric rates, size of attic, climate, etc... Plus, you can save even more with a 22% Federal Tax Credit on both the purchase price and installation costs of your Solar Powered Attic/Garage Ventilation Fan. Because these solar ventilation fans operate without fuel, waste, or pollution, they earn points towards Green building. So you can save money on electricity without using any to do it, which is green for the environment, and puts some extra green in your wallet.  For most roofs, our one piece Solar Powered Attic Ventilator is the perfect solution. Because our solar cells are highly efficient at capturing the sun’s energy, there is no need for unsightly raised panels or tracking systems. Instead, what you see is a low profile ventilator in a contoured design that integrates well with the roof.
