Brewer Cowl - Positive Up Draught Internal Dia.:8" High qualityDESCRIPTION: The 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.
