An air shaft is a vertical or horizontal passage in a building that is designed to allow air to circulate.

Definitions
An air shaft is a duct or passage that connects a building’s interior to the outside air. It can be used for ventilation or as a means of escape during a fire. Air shafts are typically found in high-rise buildings, where natural ventilation is not possible due to the height of the building.
Origin
The origin of the term air shaft can be traced back to the early 19th century. It was first used in the context of coal mines, where air shafts were used to ventilate the mines and provide fresh air to the miners. The concept of air shafts was later adapted to buildings, where they were used to provide ventilation and natural light.
