Round Back Solar Roof Exhaust Fan

Roof Ventilation that looks great while running on sunlight

The Round Back Solar Fan runs on both solar and wind power. The solar panels work best in bright direct sunlight. However, it exhausts air continuously even when there is no sun and the motor is off. This happens because of the Stack Effect. This occurs when the outdoor temperature is colder than the inside temperature. Hot air rises, so the warmer, indoor air rises upward to exit through the vent. As a result, allowing air to freely flow in and out.

This exhaust fan works best if placed near the peak of the roof. It is designed to remove hot humid air during the summer and moisture in the winter. This Solar Fan comes in an array of diameters and collar heights allowing for installation in any climate zone. See the Climate Zone Chart to determine the proper collar height for installation in your area.

The 1/8 inch louvers are designed to prevent rain, snow, insects and animals from entering inside the fan.

The fan is made of durable rust-free aluminum. Powder coating is available to match the color of your roof. For any questions please see the frequently asked questions page. If you still have questions, email the sales team [email protected] or call 845-565-7770
