Noctua NF A14 Industrial PPC 140x140x25mm PWM Fan IP52 Rated
2000 RPM 840556102410 / 3000 RPM 840556102434
Conceived for industrial heavy duty applications that require enhanced cooling performance and advanced ingress protection, the NF-A14 industrialPPC (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 and the use of a novel three-phase motor, the industrialPPC version provides superior airflow and pressure capacity while keeping noise levels and power consumption moderate as against comparable 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 Noctuas trusted reliability and 6 years manufacturers warranty, the NF-A14 industrialPPC is an ideal choice for highly demanding applications that require superior flow rates and ultimate dependability.
Award-winning NF-A14 design
Having received more than 100 awards and recommendations from the international press, Noctuas 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.
Industrial PPCversion
Thanks to its elevated top speed, the NF-A14 industrialPPC- provides a significant performance boost over the 1500rpm 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, 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.
Class-leading energy efficiency
While the standard NF-A14 is one of the most energy efficient 1500rpm 140mm fans on the market, the industrialPPC versions 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 Noctuas industrialPPC 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 Noctuas 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 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 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
Noctuas AAO (Advanced Acoustic Optimisation) 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.
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.
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 mounting systems and fan clips used on heatsinks.
SSO2 Bearing
The NF-A14 industrialPPC features the further optimised second generation of Noctuas 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 industrialPPC sports a CNC milled bearing shell made entirely from brass.
PWM Custom designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NF-A14 industrialPPC uses Noctuas custom designed NE-FD2 PWM IC for three-phase motors. The NE-FD2 integrates Noctuas proprietary Smooth Commutation Drive (SCD) technology, which suppresses PWM switching noises and thus makes the fan quieter at lower speeds.
