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

Chimney cowl for more stable flue gas extraction in wind

A self-adjusting chimney cowl with wind vane Ø250 is intended to protect flue gas extraction from the influence of wind. It is made of acid-resistant stainless steel 1.4404 and is temperature resistant up to 650 °C.

Main advantages

• Automatic turning according to the wind: the wind vane always turns the cowl 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.
• Acid-resistant stainless steel: it is made of steel 1.4404 with a sheet thickness of 0.6 mm.
• High temperature resistance: it is suitable for temperatures up to 650 °C.
• Operation without bearings: the cowl rotates on a lubricated shaft in a sleeve with a height of 120 mm.
• 2-year warranty: the product has a 2-year warranty.

Use and installation

The cowl is suitable for ventilation chimneys and for chimneys for burning wood, pellets, gas or heating oil. It is not suitable for chimneys in which coal, including pea coal, is burned.

The connection diameter is 250 mm. The cowl also works without a base. A version with a base is also available on the product page, which includes a square plate 350 mm with 4 holes Ø8 mm and a ring with clamps with a height of 110 mm. When selecting, consider the chimney diameter and the type of fuel.

Frequently asked questions

Is the cowl suitable for a Ø250 chimney?

Yes. The connection diameter is 250 mm, so it is intended for chimneys of the appropriate diameter.

How does the cowl help in wind?

The wind vane turns the cowl so that its back faces the wind. This prevents the wind from obstructing flue gas extraction and from pushing smoke back into the chimney.

Is it suitable for burning coal?

No. The cowl is not suitable for chimneys in which coal or pea coal is burned.

Conclusion

The chimney cowl with wind vane Ø250 is a suitable choice for chimneys where wind disrupts flue gas extraction. Due to the acid-resistant steel, temperature resistance up to 650 °C and self-adjusting operation, it helps improve draught and reduce smoke return.
