Polypipe Domus 40119 Circular Reducer 125 - 100mm

This circular reducer is intended for joining 125mm and 100mm ventilation ducting systems, enabling a secure connection when transitioning between duct sizes. It is suitable for use in a range of domestic or commercial applications where ventilation runs require adaptation.

On-site, this reducer is typically installed to connect different sizes of ductwork or link extract fans to smaller ducts. It supports effective air movement in areas such as kitchens, bathrooms, and utility spaces by maintaining duct system continuity where pipe size changes.
