Love the website-- really user friendly and great deals to see! Axial fans while efficient for high-volume airflow often generate noise （65–85 dBA） posing challenges in noise-sensitive environments like offices or data centers. Noise arises from blade turbulence motor vibration and airflow dynamics but advanced designs and installation techniques mitigate these issues. Blade geometry is a primary noise source. Turbulence at the leading and trailing edges creates sound radiation; poorly designed blades amplify this. Aerodynamic profiles like skewed or sickle-shaped blades reduce turbulence by 3–5 dB per ZIEHL-ABEGG. Curved blades mimicking aircraft wings smooth airflow lowering noise compared to straight blades. Adjustable pitch blades optimize flow avoiding stall regions where unstable airflow generates vortices and noise spikes. Motor quality matters. High-quality EC motors operate smoother reducing vibration-related noise by 10% versus AC motors. Low-rpm designs （1200–3600 R |
