The main purpose of the Spinner Anti Down Draught Chimney Cowl is to prevent the penetration of the chimney by moderate or severe winds which causes smoke to escape from the open fireplace or stove or any other appliance.

Thanks to ‘sail’ design blade fins the Spinner Anti Down Draught Chimney Cowl responds to wind coming from any direction

Its response is immediate because of its double bearing pivot action.  The more severe the wind – the more effective the Spinner cowl becomes.

When revolving, the Spinner Anti Down Draught Chimney Cowl also ventilates the chimney shaft helping keep it dry and it can also help prevent back up smells coming down into the room via the fireplace or stove.

Does not impede the performance of the chimney in any way.

Suitable for use with all fuels - oil, gas & solid fuels (except anthracite)

The Spinner Anti Down Draught Chimney Cowl also protects the chimney from moisture ingress and nesting birds. If your problem is excess moisture ingress a Static Anti Down Draught Chimney Cowl offers more protection from driving rain than either the Spinner Anti Down Draught Chimney Cowl or Anti Bird / Anti Rain Chimney Cowl
