The term that best describes a fan designed for a straight-line discharge of air is the axial flow fan. This type of fan operates by having the air move parallel to the axis of the fan blades, resulting in a direct, linear flow of air. Axial flow fans are commonly used in applications where large volumes of air need to be moved efficiently, such as in ventilation systems, cooling equipment, and various industrial processes.

The design of axial flow fans allows them to generate significant airflow with relatively low pressure drop, making them ideal for situations where the objective is simply to circulate air or exhaust it from a location. Their effectiveness in generating straight-line airflow is a key characteristic that sets them apart from other types of fans and blowers used in different applications.
