P-BIB14BRNLomanco Whirlybird Turbine Vent - 14"
Out Of Stock
The Whirlybird® Turbine Ventilator is an internally braced, self-flashing roof-mounted turbine attic ventilator. The 14" Big Whirly turbine moves 37% more air than the 12".
The turbine design features permanently lubricated upper and lower ball bearings that ensure long life and no maintenance.
The turbine also features rigid spider-type construction, riveted at every connection and tested to withstand winds of 110 M.P.H. Additionally, twenty-one air-foil curved vanes with rolled edges deflect water.
The Whirlybird® turbine's large flashing makes installation easy, and its 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.
