Beschreibung
Zusammenfassung:	An exemplary ventilation air mixer includes a branch air duct and a trim air mixer. The branch air duct has an inlet that is configured to be coupled to a takeoff port of a main air source duct. The branch air duct has multiple holes arranged about a wall of a mixing portion. The trim air mixer at least partially surrounds the branch air duct and forms a cavity extending from the inlet of the branch air duct to at least the mixing portion. The trim air mixer has a trim air source duct connection coupled at an angle about a midsection. The angle is substantially acute relate to a longitudinal axis of the branch air duct such that trim air entering into the trim air mixer via the trim air source duct connection is directed toward the inlet of the branch air duct.
