Features of our Butterfly Damper

Video Transcript:
Hi guys and thanks for joining me! For this video I will be explaining the key features of our Butterfly Dampers!
These are made from Galvanised Steel and come with a hand controller to move the blade. The blade allows you to regulate the air flow of the ducting system, or shut off when not in use. These can be locked in to place with a screwdriver. Our butterfly dampers are male ended so they slide easily into spiral – we stock a range of diameters from 80 -300mm, however larger sizes are available on request. They all also have a height of 190mm.
Thanks for watching and don’t forget to like and share!
