Air Duct Splitter

I made this as a splitter for the ventilation in a vintage Volvo PV. It has a 60 mm Intake and two 45 mm outlets. It has a bias system so that half of the flow goes to one side, and the rest is shared between both outlets. The reason for this is to allow more air to the passenger side.
I guess this can be used in any application where an airflow need to be shared, and biased.
