Chimney Cowls

Rotary Chimney Cowls

Chimney cowls are designed to stabilize and increase chimney draught in ventilation and smoke ducts. They are to be mounted on gravitation based ventilation chimney duct endings.

Chimney cowls are mounted on the top of chimney ducts. Their purpose is to prevent the chimney from downwind, rainwater, ice buildup and bird nesting, but most of all they are designed to generate chimney draught using force of the wind.

Chimney cowls are available in two versions, the one with flat square base is suitable for flat chimneys, while the inlet pipe version is easy to install on existing chimney tubes.
