The Noctua industrialPPC fans provide superior airflow and pressure capacity while keeping noise levels and power consumption moderate compared to other high-speed fans. While its fibre-glass reinforced polyamide construction and certified water and dust protection make the NF-A14 industrialPPC 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 and 6 year manufacturer’s warranty, the NF-A14 industrialPPC is an ideal choice for highly demanding applications that require superior flow rates and ultimate dependability.
Relaxed Tech Review
"We strongly recommend the Noctua NF-A14 industrialPPC fans to anyone who's looking for the best of the best. Noctua continues to release high quality products so with all that being said, we are proud to give both the NF-A14 iPPC-3000 and 2000RPM PWM fans our Gold Award." Full review
Features
Award-Winning NF-A14 Design
Having received more than 100 awards and 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 and pressure performance. Combined with the Industrial PPC 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 Industrial PPC 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 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 and 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 and makes the fans even more robust and break-proof than Noctua’s standard fibre-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 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
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 Optimisation) 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 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 and improved airflow and 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 screws and other mounting systems.
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 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 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 and thus makes the fan quieter at lower speeds.
6-Year Manufacturer’s Warranty
Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A14 Industrial PPC features an MTTF rating of more than 150.000 hours and comes with a full 6-year manufacturer’s warranty.
Backed by a 6-year Noctua warranty.
