Product Information


Improve the comfort, efficiency, and longevity of your home by removing hot air and moisture from your attic

Solar Attic Fan

By removing excess heat in your attic, you can be more comfortable in your home, reduce energy usage, and save money. Additionally, you can protect your investment by removing moisture build-up year-round.

  • Remove heat and moisture
  • Reduce energy usage
  • Protect your home and roof
  • Reduce premature aging of roof shingles

Cools your attic and reduces energy usage in the summer months

The Solar Powered Attic Fan 9025TR 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 ductwork and consequently heat the air passing through it, causing your air conditioner to work even harder.

Removes moisture and reduces mold in the winter months

Solar Attic Fan

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.
