The Smart Vent (Aerodyne Brewer Cowl) prevents foreign bodies entering the chimney and is designed to increase updraught and reduce downdraught.

The closed upper surface of the terminal impedes the downward movement of wind which might otherwise create a down draught within the chimney. The curved shape of the four vertical walls behaves like an aerofoil which creates a negative pressure on the inner curved edge as wind passes over and through the terminal. This action creates a suction to increase the upward chimney draught.

• Promotes positive updraught
• Helps reduce downdraught
• Prevents foreign bodies from entering chimneys
• Fits most conventional chimney pots
• Durable construction and easy to install
• Manufactured from 1.2mm thick high grade aluminium alloy
• Suitable for use on solid fuel systems - logs, coal, peat

Smart Capping is easily secured to the top of a masonry chimney which is no longer to be used. It is designed so that a narrow gap is left between the cap and the top of the chimney pot or liner to enable trickle ventilation of the flue which is necessary to prevent residual moisture in the stack creating damp problems. The gap is sufficiently narrow to prevent the entry of bats and small birds.

The 260mm Capping Cowl was designed to be used on chimneys with multiple flues, where the tight space will make it impossible to use a 350mm standard cover.

• Tested to and complies with BS EN 16475-7:2016
• Available in 2 cap sizes: 350mm and 260mm
• Made from corrosion proof stainless steel
• Fits most standard chimney pot diameters
• Prevents foreign bodies from entering chimneys
• Easy to fit with 2 stainless steel worm drive locking bands
