Chimney cowls

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

In MK Sp z o.o. offer there are rotary chimney cowls used to improve draught in ventilation ducts and self – adjusting chimney cowls that can be used for flue/smoke ducts.

• Rotary chimney cowls are devices, which, in a dynamic way, use force of the wind to increase chimney draught. The turbine always rotates in the same direction no matter of the wind strength or its direction. They are to be mounted on gravitation based ventilation chimney duct endings. 
• Self-adjusting chimney cowls are devices, which, in a dynamic way, use force of the wind to increase chimney draught. The cap always places itself in the opposite direction to the wind no matter of its strength or direction. Some versions, thanks to the materials used and their design can be mounted on flue (gas, oil) and smoke chimneys.
