Chimney cowl with wind vane on two ball bearings Ø200, acid-resistant steel (inox), up to 650 °C

Chimney cowl for stable flue gas extraction in wind

A self-adjusting chimney cowl with wind vane is intended to improve draught and protect flue gas extraction from the influence of wind. It is made of acid-resistant stainless steel 1.4404 and is suitable for a Ø200 connection.

Main advantages

• Self-adjusting wind vane: the cowl always turns with its back to the wind, so the wind does not disturb flue gas extraction and does not push smoke back into the chimney.
• Improved draught: special recesses on the cowl create negative pressure and help improve draught.
• Resistant material: it is made of acid-resistant stainless steel 1.4404 with a sheet thickness of 0.6 mm.
• High temperature resistance: the cowl is resistant up to 650 °C.
• Two bearings: it rotates on two maintenance-free ball bearings with balls in oil.
• For different fuels: it is suitable for chimneys fired with wood, pellets, sawdust, gas or heating oil.

When choosing, consider the connection diameter, fuel type and method of fixing to the chimney.
