  • Wind-powered ventilator that creates positive and negative pressures
    Patent number: 8936506
    Abstract: A wind-powered rooftop ventilator that can create both positive and negative pressures to enable the exhaust and intake of air is described. The wind-powered rooftop ventilator includes a symmetrical cap that is aerodynamically shaped such that, when wind flows against the back of the symmetrical cap, a negative pressure area is created at the front opening of the symmetrical cap, thereby enabling the exhaust of air from an indoor area. When wind flows against the front opening of the symmetrical cap, the wind is captured by the symmetrical cap, thereby enabling the intake of air into an indoor area. As such, the wind-powered rooftop ventilator can create both positive and negative pressures without use of an external power source, fan, and/or worm gear.
