Morphology
The meaning 'a passage for moving air' is transparently composed from 'air' (gases) + 'duct' (a hollow channel conveying fluid or air) and follows the regular noun–noun compound pattern in English. This compositional structure is common across languages and should be immediately understandable to a B1 learner who knows both constituents.
Etymology
The compound noun air duct shows a simple picture: air plus duct, a tube or channel, means a tube that carries air around a building. That's why it means 'a passage or pipe for moving air'.
