Important: This Spinner Anti Downdraught Chimney Cowl will fit a standard chimney pot. In Ireland, a standard chimney pot measures 8 inches internal diameter. This is the most popular sized chimney pot in Ireland. Some chimney pots measure 9 inches internal diameter and this Spinner Anti Down Draught Chimney Cowl will also fit this size.
The main purpose of the Spinner Anti Downdraught Chimney Cowl 8" 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 such as a insert stove or range.
Thanks to ‘sail’ design blade fins the Spinner Anti Downdraught Chimney Cowl 8" 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 Downdraught Chimney Cowl 8" 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 Downdraught Chimney Cowl 8" also protects the chimney from moisture ingress and nesting birds. If your problem is excess moisture ingress a Static Anti Downdraught Chimney Cowl offers more protection from driving rain than either the Spinner Anti Downdraught Chimney Cowl 8" or Anti Bird / Anti Rain Chimney Cowl
Technical:
The revolving mechanism is a sealed double bearing unit for long lasting life – the high temperature grease used is rated to 260 degrees C
Manufactured to EN16475-7:2016 and EN1856-1:2009, CE Marked Independently tested and certified by BSRIA UK

The high grade stainless steel construction & finish is of the best quality.
Has been tested for many years in the most varied of weather conditions & has proven to be successful in solving downdraught problems, regardless of wind severity.
What the Spinner Anti Downdraught Chimney Cowl 8" will not do:
Should not be used with Anthracite fuel or fuels high in sulphuric acid.
The Spinner Anti Downdraught Chimney Cowl 8" must not be used on a chimney shorter than 18 feet
Will not prevent a downdraught if the chimney is more than 4 feet lower than the apex of the roof or 4 feet lower and in close proximity to a taller structure, hedge, or tree(s)
This Spinner Anti Downdraught Chimney Cowl 8" will not prevent a draughting problem when there is no wind – if the problem still exists when there is no wind (in conditions such as cold, calm and frost) the problem is a lack of draught (not a downdraught) and an electrical chimney cowl is required such as the Super C Electric Fan Cowl. No anti downdraught chimney cowl can solve a lack of draught.
