ventilation shaft
Building's breathing tube
A ventilation shaft is a vertical or angled passage that allows air to flow into or out of an enclosed space—a mine, tunnel, building, or underground structure.
These shafts provide fresh air and remove stale or contaminated air.
In fiction, ventilation shafts are famously used as escape routes or infiltration points: The spy crawled through the ventilation shaft.
