Chimney Stack

The Aerodyne has been a favourite option among our customers for over 50 years. Time and again this cowl has proven its worth as one of the top antidowndraught cowls on the market.

Its unique venturi shaped design causes a drop in air pressure which increases the amount of draw up the flue helping to exhaust smoke and fumes efficiently.

Fixing kit included.

Rain entry into redundant chimneys is one of the main causes of structural decay to chimney stacks. The decay, caused by the natural freeze/thaw cycle of the weather, can ultimately cause great expense. Water works its way into the mortar between the brickwork and as it freezes, expands, eventually leading to cracks in the brickwork.

The Brewer Chimney Capper offers a simple solution at a low price that prevents rain, bird and debris entry while still allowing nominal ventilation.

Chimney fans are a reliable option when trying to stop downdraught issues. There are multiple options available to suit individual customers’ needs. Please contact our technical department for information and advice.

Please take note that Brewer Cowls only recommend this product as a last resort and would suggest trying some of our rotating antidowndraught cowls such as the Aspirotor before committing to the expense of a chimney fan.
