Hello,
I need to install ducting for an extraction hood in the ceiling before it is re plastered shortly.
I've not yet bought the hood but it will be a standard 600mm wide one with an extraction rate of around 400m³/hr.
Due to the narrow space I have in the ceiling, it will need to be the 203mm x 60mm flat ducting around 2m long. Will it be ok to use a reducer from the hood 150mm output flu and this size flat ducting? (below) or would it need to be bigger?...
