ROTOWENT DRAGON
Self-adjusting chimney cowl ROTOWENT DRAGON is a device dynamically using wind power to support chimney draft. Regardless of the direction, strength and type of wind, the outlet of the root cap is positioned on the leeward side of the wind blowing.
It is mounted on ventilation chimneys with gravity, combustion and smoke. Thanks to the patented method of bearing placed outside the area of high temperature of exhaust gases, it is recommended for pipes that discharge fumes from fireplaces and solid fuel stoves.
