Darco - chimney cowls - rotowent dragon square base (opened)

Rotowent dragon square (open) base is a base designed especially for use on flue and smoke ducts (from a fireplace). It uses wind most efficiently to create a chimney draft.

Open bases available only for diameters 150 to 250. Ballast - wing included.

The ROTOWENT DRAGON self- adjusting chimney cowl is a device that dynamically uses wind power to support the chimney draft. Regardless of the direction, strength and type of wind, the hubcap outlet is positioned on the leeward side of the blowing wind. It is mounted on gravitational, exhaust and smoke exhaust chimney outlets. Thanks to the patented bearing arrangement, located outside the area of high temperature, gas in flue gas is recommended for flues discharging flue gas from the fireplace and the stove for solid fuels.
