Anti-Downdraught Cowl


Availability: In Stock

Price: 0.00

The Anti-Downdraught Cowl eliminates down draughts in all weather conditions. Even if the wind is blowing vertically down, the cowl will convert that energy into a positive up draught. Pilot lights that extinguish themselves, due to down draught will keep alight.

The Cowl is non-directional and therefore does not have to be fitted facing in any particular direction, and it has no moving parts that can seize up. Rain, snow and birds are prevented from entering the chimney.

The design, which has been proven over many years, ensures that the cowl will continue to ventilate the chimney when the fire or appliance is unlit.

The Anti-Downdraught Cowl is manufactured in 0.5mm 430 grade stainless steel for use with Gas, or in .8mm 316 grade stainless steel for the greater corrosion resistance required with solid fuel and oil, it is available in 100mm to 300mm diameters.

Fitting is simple, the stem of the cowl is slightly undersize so that it can slide down inside the bore of most prefabricated metal chimneys, liners or conventional brick chimneys. This joint should be sealed.

Please ensure that the fire/appliance has enough combustion air to operate correctly. Many combustion air problems are caused by excessive draught proofing which can deprive the fire of the oxygen it requires to burn efficiently.
