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]. This linear flow is achieved through the aerodynamic design of the fan blades which function similarly to an airplane‘s wing or propeller[4]. As the motor drives the hub and the attached blades to rotate the airfoil shape of each blade creates a pressure differential[2]. The convex （curved） side of the blade experiences lower pressure while the concave （flatter） side experiences higher pressure. This pressure difference generates an aerodynamic lift force and because the blades are angled this lift force is primarily di |
