. Engineering Principles and Design of Axial Fans
Axial fans operate on the fundamental principle of generating airflow parallel to the fan's shaft axis, where rotating blades impart kinetic energy to the air, creating a pressure difference that drives flow. This design excels in high-volume, low-pressure applications, with efficiency optimized by factors like blade number (typically 2-6), shape, and hub-to-tip ratio.

Axial Fans for Server Racks is a critical topic in modern industry as thermal stability directly impacts performance, safety, and operational efficiency. DC and AC axial fans continue to be the preferred air‑movement solution due to their compact structure, high airflow capability, and flexible voltage options.
