Which ventilator works by rotating to draw attic air towards it?

The correct answer is C, Turbine Ventilators, as these devices are specifically designed to enhance ventilation in attics by utilizing wind power. When wind blows, it causes the turbine vents to rotate. This rotation creates a negative pressure area that helps to draw stale or hot air out of the attic space. The effectiveness of turbine ventilators comes from their ability to actively remove air, which can significantly reduce indoor temperatures and improve air circulation, particularly in warmer climates.

On the other hand, eave vents primarily function by allowing cool air to enter the attic from the lower areas, enhancing natural airflow when paired with other vents. Louvers and static roof vents do not have moving parts; hence they rely on the natural convection of air to promote ventilation without actively drawing air out of the attic. Unlike turbine ventilators, they do not create a suction effect, making them less effective in drawing warm air out under certain conditions.
