Vaneaxial

Vaneaxial refers to a type of fan that combines features of both vane-type fans and axial flow fans. A vaneaxial fan is an axial flow fan that incorporates stationary guide vanes. These guide vanes are typically located downstream of the fan impeller. Their primary function is to straighten the swirling airflow produced by the rotating impeller. This straightening action converts some of the rotational kinetic energy of the air into static pressure, thereby increasing the overall efficiency of the fan. Vaneaxial fans are commonly used in applications where high efficiency and moderate pressure are required, such as in industrial ventilation systems, HVAC systems, and wind tunnels. They are known for their relatively compact design compared to other fan types that can achieve similar pressure gains. The presence of the guide vanes adds to the overall length of the fan housing. The impeller of a vaneaxial fan is similar to that of a standard axial fan, featuring blades that move air parallel to the axis of rotation. The guide vanes are typically aerodynamically shaped to minimize drag and maximize the conversion of swirl to pressure.
