Brand：Lomanco
The Lomanco Whirlybird Wind Turbine Ventilator harnesses the natural power of the wind to efficiently expel heat and moisture from your attic or roof space, helping to reduce energy costs and extend the life of your roof. Crafted from 100% rust-free aluminum, this turbine features 21 precision air-foil vanes, each individually riveted for maximum strength and water deflection. Designed for both internally and externally braced models, the Whirly bird Lomanco offers unmatched durability, with permanently lubricated upper and lower ball bearings ensuring smooth, maintenance-free operation. Its exclusive vari-pitch base easily adjusts to a 12/12 roof pitch, and the unit has been tested to withstand winds up to 110 mph, guaranteeing long-lasting reliability in any climate. Available in 12", and 14" sizes, the 14 Big Whirlybird moves up to 37% more air than the 12 version, making it ideal for larger ventilation needs.
