Elongated rotating chimney cowl Ø150 with base, aluminium

Rotating cowl for better draft in the ventilation flue

The elongated rotating chimney cowl made of aluminium sheet is intended for ventilation flues with a connection diameter of 150 mm. The wind turns the cowl head, which creates negative pressure in the ventilation duct and thus improves the draft.

Main advantages

• Improved draft: the wind-driven rotation of the head creates negative pressure in the ventilation duct.
• Protection against reverse draft: the cowl helps prevent air from returning through the ventilation flue.
• Protection against precipitation: the top protects the flue from direct ingress of precipitation.
• Aluminium design: made of aluminium sheet.
• Base included: the base plate measures 250 × 200 mm and is part of the cowl.
• 2-year warranty: the product comes with a 2-year warranty.

Use and installation

The cowl is intended for use on ventilation flues with a connection diameter of Ø150. Due to its elongated shape and rotating head, it is suitable for improving draft in the ventilation duct and for protecting the top against precipitation.

When choosing, consider the connection diameter of 150 mm, the diameter of the rotating part of 190 mm and the total height of 340 mm. The base with a 250 × 200 mm plate is part of the cowl, so check compatibility with the installation location before fitting.
