The items included with this Item description are vaneaxial fan assemblies or an axial fan impeller. An axial fan impeller is a type of fan that causes gas to flow through it in an axial direction, parallel to the fan axle. Maximum gas pressure is observed at the discharge of the impeller blade and minimum pressure on the side opposite to the discharge side. A vaneaxial fan assembly is an axial fan impeller contained within a housing that includes vanes designed to straighten air flow to more efficiently pass through a heat exchanger to maximize heat rejection.
