1. The Fundamental Principle: How Axial Fans Achieve Linear Airflow
The axial fan is the most ubiquitous form of air-moving machinery, defined by its core operating principle: moving gas parallel to the axis of the rotating shaft[1]. Unlike centrifugal fans, which move air radially (at a 90-degree angle), axial fans draw air in and discharge it in a straight line, making them ideal for high-volume, low-pressure applications[2][3].
