Stainless Steel Chimney Self Adjustable Cowl. Chimney cowls prevent backdraft and protect the flue from weather effects like snow and rain. The main function of cowls is to support a weakened draft. Chimney cowls utilise the energy of the wind and create exhaust vacuum which stabilises the draft. They are fitted on top of combustion, smoke and ventilation chimneys. Wind directional cowls (“Fireman” type) are constructed in a way that allows them to shift position in relation to wind direction. Even the smallest gust makes them rotate, which creates exhaust vacuum that sucks combustion gases out of the flue. They greatly improve the performance of heating appliances.
