Air Cyclone/Wind Driven Ventilator

A roof turbine cyclone ventilator is a wind-powered device designed to provide natural ventilation for buildings. Shaped like a rounded dome with evenly spaced fins or vanes, it sits atop the roofline, catching even the slightest breeze. As wind flows over and around it, the ventilator spins in a smooth, continuous motion, creating a cyclone-like suction effect that draws hot, humid, or polluted air up and out of the interior space.
