How it's used
Primarily used in the context of mechanical ventilation, particularly regarding kitchen or bathroom exhaust systems. While it literally refers to the action of extracting air, it is almost exclusively paired with 扇 to refer to the appliance itself. It is rarely used to describe the general concept of room ventilation, for which people prefer terms like 通風.
Examples
The exhaust fan in the kitchen is broken.
Turn the exhaust fan up higher to ventilate the room.

exhaust fan
Common mistake
Do not use this to mean breathing or inhaling air, as that would be 吸氣. It specifically refers to the mechanical removal of air from a confined space.
