New Darco Dragon Cowl

Hi, New Darco Dragon Cowl 10" The Anti-Downdraught Chimney Cowl self-adjusting chimney DRAGON is a device that, dynamically, utilises the force of the wind to increase chimney draught. The cap always places itself in the opposite direction to the wind, no matter its strength or direction. It is to be mounted on gravitation-based chimney ducts endings: flue (gas, oil, solid fuel) and smoke. Thanks to the special, patented, rotating system with ball bearings placed outside the cap, it can withstand very high temperatures, which can be achieved in wood or coal-burning stoves.
