A variety of styles to choose from: 40/50/60/70/80/90/120mm Voltage: DC5V, DC12V, DC24V Large air volume, efficient heat dissipation. High speed and large air volume, scientific fan blade design to increase wind pressure reasonably. Engineering mechanics, reducing air friction, quiet wind noise. Pure copper wire core, high efficiency and stability, pure copper material, strong conductivity, durable, stable and safer. Angled blades. The new blade design increases the air volume by 9% and reduces the noise by 5% compared with the previous generation. High-purity coils. Cold-rolled silicon steel sheet, ultra-high-purity coil, up to 12 grades, higher efficiency, providing stable and surging power for the fan.
