General Small Vaneaxial Information

These are compact, high-speed fans whose airflow is parallel to the motor shaft.  The impeller and guide vanes are of airfoil construction for maximum aerodynamic efficiency and minimum acoustical noise.

Vaneaxial fans are designed for use in tightly packaged airborne “black boxes” where sizes and weight must be held to an absolute minimum, where

reliability is critical, and where high heat loads must be dissipated with cooling air.
