Self-adjusting chimney cowl ROTOWENT TWISTER 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. Its advantage is simple, reliable construction and low price.
application:
– support of gravitational exhaust ventilation and draft in the flue and smoke chimneys
– when there are air swirls at the outlet of the chimney
– with unfavorable terrain configuration, strong and frequent winds
– in the absence of a stabilized chimney draft or when it is too small
