Lomanco Whirlybird BIB-14WB Turbine Ventilator, 14 in Dia Throat, Aluminum, Weathered Bronze

Lomanco Turbine Ventilators are available in three sizes - 8, 12 and 14 in. The 14 in Big Whirlybird Turbine moves 37% more air than the 12 in Whirlybird Turbine. The 12 in Whirlybird Turbine is available in aluminum and galvanized finishes, as well as a tile roof design. Whirlybird turbines are also available in two models - internally or externally braced. While both internally and externally braced turbines have the same internal construction, our externally braced turbines have three braces surrounding the outside of the turbine.
