Morphology
The meaning 'a device used to move air' is directly and transparently derived from combining 'air' (the gas) with 'pump' (a machine that forces fluids or gases), yielding a pump intended for air. This noun–noun compounding pattern is cross-linguistically common and follows straightforward compositional semantics, so a B1 learner who knows both constituents will readily understand it.
Etymology
Air pump is named for what it does: air is what moves and the pump is the tool that pushes it, so imagine pushing a handle and forcing air into a bicycle tyre or a balloon. Because it literally moves air in or out, the phrase means 'a device used to move air into or out of an object or space'.
