  • Flow Acceleration Channels; Reduced Motor Hub Size
  • Integrated Anti-Vibration Pads; Smooth Commutation Drive 2; SSO2 Bearing
  • Low-Noise Adaptor for full flexibility
  • 3 to 2-pin Adaptor and Polarity Protection
  • Extensive cabling options; 6-year manufacturer's warranty
  • The NF-A4x10 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.
  • Thanks to its streamlined, compact motor design, the NF-A4x10's motor hub is smaller than with conventional 4cm fans. This allows for more blade surface area and thus contributes to the NF-A4x10's superior airflow and pressure performance.
