MAD Spinner Stainless Steel Chimney Cowl

The MAD Spinner cowl is a directional cowl that provides complete dynamic protection from downdraughts, whilst the rotating action assists ventilation. To work properly a chimney must have draw, both to clear the products of combustion and to provide fresh combustion air to the fire. Because the spinner cowl rotates, a low pressure zone is created just above the chimney pot, resulting in better chimney function. The base of the spinner cowl is made from die cast aluminium with a strong cross section to give support and strength to the rotating spinner. The fins are made from stainless steel and are spot woven into place and then spot welded giving extra strength during rotation. All MAD Spinner cowls are supplied complete with a strap fixing kit, the most secure fixing available, and highly recommended for revolving chimney cowls.

Suitable for use with Coal, Seasoned Wood and Gas. The MAD Spinner Chimney Cowls are available in 3 colours: Terracotta, Black and Stainless Steel.
