Turbine installation

Lomanco is the home of the one and only 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® wind turbines are available in three sizes—8", 12", and 14". The 14" Big Whirly turbine moves 37% more air than the 12". The 12" 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 the internally and externally braced turbines both have the same internal construction, the externally braced turbines have three braces that surround the outside of the turbine.

Common Features

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 M.P.H.,21 air-foil curved vanes with rolled edges to deflect water, and 100% rust-free all-aluminum construction.

Easy Installation

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.
