Noctua IndustrialPPC NF-A14 - Case fan NF-A14 IPPC-3000 PWM

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. 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. 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. 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 versions three-phase motor provides a further 10% reduction in power consumption when compared at 2000 rpm. 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. 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. AAO frame. Noctuas AAO (Advanced Acoustic Optimization) frames feature integrated anti-vibration pads as well as Noctuas proprietary stepped inlet design and inner surface microstructures, both of which further refine the fans performance/noise efficiency. Three-phase motor design. While most axial fans use single-phase motors with 4 slots, Noctuas 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. 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. Fiber-glass reinforced polyamide construction. Both the impeller and the frame of Noctuas 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 Noctuas standard fiber-glass reinforced PBT fans. SSO2 bearing. The NF-A14 industrialPPC features the further optimized second generation of Noctuas renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilization, precision and durability. Stepped Inlet design. Noctuas 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.
