Noctua IndustrialPPC NF-A14 - Case fan - 140 mm

Key Features and Benefits:

• 2000 rpm industrialPPC version
  Thanks to its elevated 2000 rpm top speed, the NF-A14 industrialPPC-2000 provides a significant performance boost over the 1500 rpm retail version. Combined with the industrialPPC series' robust polyamide construction and advanced protection features, this makes the fan ideal for challenging industrial applications.
• Three-phase motor design
  While most axial fans use single-phase motors with 4 slots, Noctua's industrialPPC fans feature a three-phase design with 6 slots, which provides smoother transitions between the slots and thus allows for even higher running smoothness, further reduced vibrations and unprecedented energy efficiency.
• Class-leading energy efficiency
  While the standard NF-A14 is one of the most energy efficient 1500 rpm 140 mm fans on the market, the industrialPPC version's three-phase motor provides a further 10% reduction in power consumption when compared at 2000 rpm.
• Fiber-glass reinforced polyamide construction
  Both the impeller and the frame of Noctua's industrialPPC fans are made entirely from fiber-glass reinforced polyamide. This material can withstand high temperatures and makes the fans even more robust and break-proof than Noctua's standard fiber-glass reinforced PBT fans.
• Certified IP52 water- and dust protection
  Thanks to a special varnish coating that covers the motor and PCB, the NF-A14 industrialPPC complies with the ingress protection rating IP52. This means that it is not only highly dust resistant but also withstands dripping water equivalent to 3 mm rainfall per minute.
• Flow acceleration channels
  The NF-A14 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.
• AAO frame
  Noctua's AAO (Advanced Acoustic Optimization) frames feature integrated anti-vibration pads as well as Noctua's proprietary stepped inlet design and inner surface microstructures, both of which further refine the fan's performance/noise efficiency.
• Stepped Inlet design
  Noctua's stepped Inlet design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space restricted environments.
• Inner surface microstructures
  With the tips of the fan blades ploghing through the boundary layer created by the inner surface microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.
• Integrated anti-vibration pads
  Integrated anti-vibration pads made from extra-soft silicone minimize the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks.
• SSO2 bearing
  The NF-A14 industrialPPC features the further optimized second generation of Noctua's renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilization, precision and durability.
• Metal bearing shell
  In order to guarantee the highest possible degree of manufacturing precision, minimum tolerance and excellent long-term stability, the NF-A14 industrialPPC sports a CNC milled bearing shell made entirely from brass.
