Rotary chimney cowls

Wind makes them rotate and create chimney draught in ventilation ducts.


Rotary chimney cowls are devices, which, in a dynamic way, use force of the wind to increase chimney draught. The turbine always rotates in the same direction no matter of the wind strength or its direction. They are to be mounted on gravitation based ventilation chimney duct endings. 

Types of rotary chimney cowls
