Noctua NF-A14 Industrial PPC 3000RPM PWM 140mm High Performance Fan Conceived for industrial heavy duty applications that require enhanced cooling performance & advanced ingress protection, the NF-A14 industrial PPC (Protected Performance Cooling) is a ruggedised high-speed version of the award-winning retail model. Thanks to the outstanding aerodynamic efficiency of the NF-A14 design & the use of a novel three-phase motor, the industrial PPC version provides superior airflow & pressure capacity while keeping noise levels & power consumption moderate as against comparable high-speed fans. While its fibre-glass reinforced polyamide construction & certified water & dust protection make the NF-A14 industrial PPC suitable for operation in challenging environments, the renowned SSO2 bearing technology guarantees an MTBF of over 150, 000hrs. Topped off with Noctua's trusted reliability & six year manufacturer's warranty, the NF-A14 industrial PPC is an ideal choice for highly demanding applications that require superior flow rates & ultimate dependability. Features Based on the award-winning NF-A14 design 3000rpm PWM industrial PPC version Three-phase motor design Fibre-glass reinforced polyamide construction Certified IP52 water & dust protection Integrated Anti-Vibration Pads Six year warranty Award-winning NF-A14 design Having received more than 100 awards & recommendations from the international press, Noctua's NF-A14 has become a proven premium choice for 140mm cooling needs. Its renowned efficiency has convinced tens of thousands of customers all over the world. 3000rpm industrial PPC version Running twice as fast as the 1500rpm retail version, the NF-A14 industrial PPC-3000 provides extreme airflow & pressure performance. Combined with the industrial PPC series robust polyamide construction & 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 industrial PPC fans feature a three-phase design with 6 slots, which provides smoother transitions between the slots & thus allows for even higher running smoothness, further reduced vibrations & unprecedented energy efficiency. Class-leading energy efficiency While the standard NF-A14 is one of the most energy efficient 1500rpm 140mm fans on the market, the industrial PPC version's three-phase motor provides a further 10% reduction in power consumption when compared at 2000rpm. Fibre-glass reinforced polyamide construction Both the impeller & the frame of Noctua's industrial PPC fans are made entirely from fibre-glass reinforced polyamide. This material can withstand temperatures up to 140°C & makes the fans even more robust & break-proof than Noctua's standard fibre-glass reinforced PBT fans. Certified IP52 water- & dust protection Thanks to a special varnish coating that covers the motor & PCB, the NF-A14 industrial PPC complies with the ingress protection rating IP52. This means that it is not only highly dust resistant but also withstands dripping water equivalent to 3mm rainfall per minute. Flow Acceleration Channels Designed for pressure demanding applications such as heatsinks & radiators, the Focused Flow„¢ frame features eleven stator guide vanes that straighten, channel & focus the airflow, which allows the NF-A14 to rival the performance of conventional fans running at much faster speeds. AAO Frame Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design & 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 & increases suction capacity, especially in space restricted environments. Inner Surface Microstructures With the tips of the fan blades ploughing 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 & enhanced airflow & pressure efficiency. Integrated Anti-Vibration Pads Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems & fan clips used on heatsinks. SSO2 Bearing The NF-A14 industrial PPC features the further optimised 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 stabilisation, precision & durability. Metal bearing shell In order to guarantee the highest possible degree of manufacturing precision, minimum tolerance & excellent long-term stability, the NF-A14 industrial PPC sports a CNC milled bearing shell made entirely from brass. Custom designed PWM IC with SCD Supporting fully automatic PWM speed control, the NF-A14 industrial PPC uses Noctua's custom designed NE-FD2 PWM IC for three-phase motors. The NE-FD2 integrates Noctua's proprietary Smooth Commutation Drive (SCD) technology, which suppresses PWM switching noises & thus makes the fan quieter at lower speeds. Six years manufacturer's warranty Noctua fans are renowned for their impeccable quality & outstanding longevity. Like all Noctua fans, the NF-A14 industrial PPC features an MTBF rating of more than 150.000 hours & comes with a full 6 years manufacturer's warranty.
