Our Buttefly Damper is designed to block the outside elements from entering the Extractor System, whilst still allowing for free air flow out of the Extractor System, when the Extractor Fan is in use.


The Butterfly Damper locates directly onto the Extractor Fan at the top of the Extraction system.
