WHB Series


The Whirly reduces summer temperatures inside the building by helping ceiling insulation to work more effectively. Because it is powered by the wind, it is very cost effective and therefore saves energy in summer. In winter it reduces condensation in roof spaces.
The Whirly helps extract fumes and also protects paint and insulation.

The Whirly is an Stainless Steel construction turning on ball bearings with a turbine ventilator.  The 21 aerofoil blades are shaped to prevent rain and dust from penetrating the unit. It is tested to withstand hurricane-force winds and temperatures up to 80°C.
The Whirly is resistant to rust and corrosion and the bearings are lubricated with heat-resistant grease and permanently sealed.
