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.

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.
Lomanco® Whirlybird® Bearings
Only the finest quality American-made bearings are used in the Lomanco® Whirlybird® turbine ventilator. Other turbines may skimp on bearing quality, but at Lomanco, we know that bearings are the heart of the turbine. If they’re out of round, poorly sealed or made with inferior materials, they simply won’t last or run as quietly as the Whirlybird turbine.
Compare and you’ll see the difference. You’ll see why Lomanco lasts forever. Guaranteed.

Molded and fully machined raceways for low drag and quiet operation.
DuPont Delrin® inner and outer bearing rings – the longest lasting and smoothest polymer ball bearing material available.

The Lomanco Whirlybird turbine and Big Whirly® turbine are guaranteed forever.
