The Round Back Attic Fan is a small low profile residential fan. It will exhaust air continuously even when the motor is off. It also works passively because of the Venturi Effect. This occurs when the wind blows against the outer louver to create an upward draft. As a result, allowing air to freely flow in and out. This residential attic fan is perfect for removing hot humid air from the attic during the summer. In addition, it will remove moisture from the attic during the winter. This will help to complete proper attic ventilation.
The Round Back Fan is ideal for venting out bathroom fans or range hoods. In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph. The Round Back Fan is great for residential roof applications because of its low profile. It can also be painted to match the color of the asphalt shingles.
