Chimney cowl with wind vane on two ball bearings Ø250, acid-resistant steel (inox), up to 650 °C

Self-adjusting chimney cowl for improved chimney draft

Chimney cowl with wind vane Ø250 is intended to protect the flue gas outlet from the influence of wind and to improve draft. It is made of acid-resistant stainless steel 1.4404 and is suitable for use at temperatures up to 650 °C.

Main advantages

• Self-adjusting operation: the wind vane always turns the cowl with its back to the wind, so the wind does not disturb the flue gas outlet.
• Less smoke backflow: the design of the cowl prevents the wind from pushing smoke back into the chimney.
• Improved draft: special recesses on the cowl create negative pressure and help more efficient removal of flue gases.
• Resistant material: acid-resistant stainless steel 1.4404 with a sheet thickness of 0.6 mm is suitable for more demanding chimney conditions.
• Two ball bearings: the cowl rotates on two maintenance-free ball bearings with balls in oil.
