Motorized roof exhaust fans (also called power roof extractors) are electrically powered forced-ventilation systems installed directly on building roofs. Unlike passive or wind-driven turbine ventilators that rely strictly on ambient wind currents, motorized units use an electric motor (typically 0.5 HP to 3 HP or more) to drive high-capacity axial or centrifugal fan blades.
This guarantees constant, controllable, and high-volume air extraction regardless of weather conditions or wind speeds.
