Dixon Hall 2010 Wilkinson 2017. The air is pressurized by aerodynamic fan blades much like a propeller and an airplane wing frequently used in exhaust applications where air particulate sizes are small such as dust streams smoke and steam and applications that require reverse airflow. As a general rule axial fans are preferred for high volume low pressure and non-ducted systems. The flow is axial at entry and exit. An axial fan is a type of fan that causes gas to flow through it in an axial direction parallel to the shaft about which the blades rotate.
By comparison a centrifugal or radial flow fan moves air perpendicular to the axis of rotation.
