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. It works passively because of the Venturi Effect. When the wind blows against the outer louvers this creates an upward draft which allows air to freely flow in and out of the vent.
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. This Attic Fan is also available with an optional Shut-Off Switch.
The fan is made of durable rust-free aluminum. Powder coating is available to match the color of your roof. For any questions, please e-mail us at [email protected] or give us a call at 1-800-766-3836
