Static chimney cowl H-TYPE 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.

USAGE:

• when there are wind fluctuations on the chimney duct ending, caused by its bad location
• when there sto unfavorable terrain configuration, with strong and frequent winds
• when there is a lack of chimney draught or it stoo weak
• in order to improve the natural (gravitation) ventilation.
