Rotowent DRAGON Self-adjusting chimney cowl 8"
 
Self-adjusting chimney cowl Rotowent DRAGON is a device, which, in a dynamic way, uses force of the wind to increase chimney draught. The cap always places itself in the opposite direction to the wind no matter of its strength or direction.
It works on the same principle as a lobster cowl.
 
It is to be mounted on gravitation based chimney ducts endings: flue (gas, oil) and smoke. Thanks to the special, patneted, 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
 
Warranty: 2 years
 
USAGE:
• When there are wind fluctuations on the chimney duct ending, caused by its bad location
• When there is an unfavorable terrain configuration, with strong and frequent winds
• When there is a lack of chimney draught or it is too weak
• In order to improve the natural (gravitation) smoke chimney draught
