Self-adjusting chimney cowl Rotowent DRAGON is a device, which, in a dynamic way, uses 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.

When to use:

  • when there are wind fluctuations on the chimney duct ending, caused by its bad location
  • when there is downdraught
  • when there is an unfavourable 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
