Lomanco is the home of The Original Whirlybird® Turbine Ventilator, the All-Weather Turbine Vent. Whirlybird® Turbines offer all of the essentials for energy savings and are geared toward going green.

Lomanco® Turbine Ventilators are available in three sizes—8″, 12″, and 14″. The 14″ Big Whirlybird® Turbine moves 37% more air than the 12″ Whirlybird® Turbine. The 12″ 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.

Common Features

All Lomanco® Whirlybird® Turbines come with the Forever Guarantee, 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 M.P.H., 21 air-foil curved vanes with rolled edges to deflect water, and 100% rust-free all-aluminum construction.

Installation

The Whirlybird® Turbine features large flashing, making installation easy. The Whirlybird® turbine has an exclusive vari-pitch base that 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.
