MVHR 90mm Semi Rigid to Air Valve

[James-the-doubter]

Hi All,

feel like this is a silly question as i can't find the answer anywhere - indictaing that no one has ever needed to ask - but can anyone offer any guidance on connecting a 90mm semi-regid QuietVent duct to a 100mm air valve?

Use a duct adaptor

Usually your 75mm or 90mm duct connects to a plenum, that provides a 125mm outlet for an air valve

Is there a single connection plenum for a 90mm duct? Can only see a two duct connection and they’re quite expensive

Thanks - where would one find such a beast for 90mm duct to an air valve

They do: https://www.bpcventilation.com/90-single-plenum-90mm-round-pipe-pvc

But a dual one is cheaper, and they come with a blank for the second connection: https://www.bpcventilation.com/quiet-vent-90mm-plenum

In fact, this is all of the 90mm range!
