Backward Courve Impeller

A backward-curved impeller is a type of centrifugal fan or blower component used in various HVAC (Heating, Ventilation, and Air Conditioning) systems, industrial applications, and other air-moving equipment. The term "backward-curved" refers to the shape or orientation of the blades on the impeller. In a backward-curved impeller, the blades curve away from the direction of rotation. This design is characterized by the curved shape of the blades, which helps to direct airflow efficiently and reduce noise and turbulence.
