Aerodynamics is a crucial aspect when designing blades for centrifugal blower fans. The efficiency of these fans depends on the careful consideration of blade geometry and impeller design. In this article, we will delve into the essence of aerodynamics in centrifugal blower fan efficiency and explore the balancing of blade geometry for optimal efficiency and noise considerations. Additionally, we will discuss the use of backward-curved impellers to achieve a balance between efficiency and pressure.
