Dragon - Square Base

Cowls designed especially for smoke ducts – the unique construction makes it extremely durable against temperature. The Dragon self-adjusting chimney cowl is a device that uses the force of the wind to increase chimney draft. The cap always places itself in the opposite direction to the wind regardless of its strength or direction. It is mounted on gravitation based chimney duct endings: ventilation, flue (gas, oil) and smoke. Thanks to the special, patented, rotating system with ball bearings placed outside the cap, it can withstand the very high temperatures that occur when using a wood or coal burning stoves.
