This hybrid rooftop ventilator combines gravity and motorized ventilation to reduce the cost of energy for cooling and ventilation in a wide spectrum of building types. Its high-performance turbine delivers higher cfm than gravity ventilators with flat rainproof hats, resulting in more free air flow from wind or hot air.

An EC German motor boosts the air flow further. Available in 16-, 24-, and 36-inch throats delivering 1,400, 2,519 or 5,885 cfm and consuming 68, 106, or 260 watts.
