Professional grade Solar Attic Fan. New patent pending enhanced design will ventilate up to 2400 square feet of attic space with a single fan. The new, patent pending, Smooth-air Deflector in the shroud of the fan produces a smoother air flow and increases exhaust performance by up to 30% from previous models. This next generation solar powered attic fan is our most powerful and efficient model yet.

Cool your home in the summer. The Professional Series Solar Powered Attic Fan 9920TR effectively reduces attic heat build-up in the summer months and moisture in the winter months. With 43% of air conditioning base on high attic temperatures frequently up to 160F, lowering attic heat typically lowers air conditioning run-time.

Installing a Solar Powered Attic Fan will help remove the heat build-up in your attic and bring your attic’s temperature down closer to the ambient outside temperature. The reduction in attic temperature will also benefit the homeowner by preserving and extending the life of the roofing and attic construction materials. Additionally, hot air in your attic can then heat the metal exterior of your HVAC duct work and consequently heat the air passing through it, causing your air conditioner to work even harder.

Remove damaging moisture. In the winter months, the building materials in your attic can absorb up to 28 gallons of moisture, contributing to mold and mildew growth. Moisture migrates into the attic space from daily activities such as running the dishwasher, showers and cooking. Additionally, warm attic air meeting the cold roofing materials creates condensation, which drips onto the attic insulation causing it to lose its effectiveness. Warm attics in winter also contribute to ice damming as the snow melts on the roof and re-freezes at the eaves, causing water to accumulate.

Installing a Solar Powered Attic Fan will allow for better air flow and moisture control inside your attic and prevent the condensation which can lead to mold and mildew problems. Approved by Florida Building Codes and Texas Department of Insurance to withstand severe weather.
