Lomanco Whirlybird BEB12B Turbine Ventilator, 12 in Dia Throat, Aluminum, Black

All Lomanco Whirlybird turbines come with a lifetime transferable warranty. Simply put, you can't buy a better turbine. The turbine design features permanently lubricated upper and lower ball bearings that ensure long life and no maintenance. Other common features of the turbine are its rigid spider-type construction riveted at every connection and tested to withstand winds of 110 mph, 21 air-foil curved vanes with rolled edges to deflect water and 100% rust-free all-aluminum construction. The Whirlybird turbine's large flashing makes installation easy. The Whirlybird turbine's exclusive vari-pitch base adjusts to a 12/12 roof pitch for use on many roof applications. When installed properly, the Whirlybird turbine reduces energy bills and the likelihood of winter ice buildup.
