Wind Driven Terminal Additional Information
The Wind Driven Terminal is a British made revolving cowl designed to eradicate downdraught whilst the rotating action assists ventilation.
The Spinners are available with either the traditional chimney fixing method base or a cap base which makes the product less prone to allowing rain and debris to penetrate the chimney.
Tested to BS715: 1993 and against BSEN 1856.
Both bases are made for Prime Aluminium Sheet which is less porous than gravity cast bases.
The 12mm diameter centre shaft is made to a very tight tolerance which allows the bearing mechanism inside to run more smoothly and freely, thus giving ultimate draw qualities.
