Lüfterrads

Lüfterrads, also known as a fan wheel or impeller, is a mechanical component designed to move air or other gases. It typically consists of a hub with a series of blades or vanes attached. When the Lüfterrads rotates, its blades impart kinetic energy to the surrounding fluid, causing it to be drawn in from one side and propelled outwards. This action creates airflow.

The design of a Lüfterrads can vary significantly depending on its intended application. Common types include axial flow fans, where the air moves parallel to the axis of rotation, and centrifugal fans, where the air is drawn in axially and discharged radially. The shape, number, and angle of the blades are critical factors influencing the fan's efficiency, airflow rate, and pressure generation.

Lüfterrads are integral components in a wide range of systems. They are used for cooling in electronics, HVAC (heating, ventilation, and air conditioning) systems, automotive engines, and industrial machinery. They also find applications in ventilation systems, dust collection, and pneumatic conveying. The materials used in their construction range from plastics and aluminum to steel and specialized alloys, chosen based on factors such as operating temperature, corrosive environments, and required strength. The performance of a Lüfterrads is often described by its airflow capacity and static pressure, which are determined through performance curves generated during testing.
