Key principles include blade aerodynamics, motor efficiency, and housing configuration, balancing airflow, pressure, and energy use. Blade design is central. Typically, 2–20 blades, shaped like airfoils, generate lift, creating a pressure differential that drives airflow. Sat, 13 Dec 2025 13:25:22 UTC en
