Fan Impeller System For Configuring And Constructing A Fan Impeller

A fan impeller system, comprising:

• a rotor element, a multiplicity of fan impeller blades and a multiplicity of adapter elements;
• the rotor element has a multiplicity of receptacles that are evenly distributed in its circumferential direction on an adapter element, from the multiplicity of adapter elements, can be arranged on each receptacles;
• a fan impeller blade, from the multiplicity of fan impeller blades, can be respectively arranged on an adapter element, the adapter element is arranged between the respective fan impeller blade and the respective receptacle and the respective fan impeller blade is connected to the rotor element by the adapter element;
• the adapter elements, from the multiplicity of adapter elements, can be selected from a group of adapter element types that differ at least in their shape and/or dimensions, and the fan impeller blades, from the multiplicity of fan impeller blades, can be selected from a group of fans impeller blade types that differ at least in their shape and/or dimensions;
• and a fan impeller that is suitable for a predetermined application can be configured by selecting an adapter element type that is suitable for the application from the group of adapter element types and a fan impeller blade type that is suitable for the application from the group of fan impeller blade types and can be constructed by mounting the adapter elements and the fan impeller blades on the rotor element.
