Static chimney cowl CAGI is a device, which uses the dynamic force of the wind to increase the chimney draught. The head creates a pressure difference forcing the air in the duct to move up. It is to be mounted on gravitation based chimney ducts endings: ventilation or flue-gas heating (dry fumes).


!   This cowl, as all cowls of Darco production, is openable, which allows the cowl to be opened easily in case of cleaning purpouses.
