What does the fan symbol represent in TPC schematics?

The fan symbol in TPC schematics represents a visual depiction of ventilation or air movement, typically featuring rotating blades. This symbol effectively conveys the functionality of a fan, illustrating its role in facilitating airflow within a system. This representation helps technicians and engineers quickly identify fan components within complex schematics, ensuring that they can easily understand the layout and arrangement of various parts within a project.

Each option presents a different geometric representation, but only the icon showing rotating blades accurately captures the essential characteristics and purpose of a fan. The other shapes, such as lines, squares, or triangles, do not convey the specific mechanical function and visual aspect associated with a fan's design and operation.
