Our BIG BIRD roof mounted Turbines has no bearings.
It operates on a machine hardened pivot device.
So no more bearings packing up due to loss of lubrication.
The base and adjustable neck is fabricated from 0.6 galvanize Steel. This gives the Turbine a strong and sturdy foundation to sit on. This type of construction prohibits any movement in high winds to unbalance the Turbine thus causing the Turbine to break up.
Our Big Bird is manufactured from imported aluminum and is super light.
Lightweight construction allows for unhindered spinning resulting in effective and efficient
Ventilation.
A Unique soaker sheet, to prevent leaks to suit most roof types. A specially machine form pressed Trimmer for the underside of the Turbine, to protect your roof insulation
