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. The 24V variant uses a dedicated wide
input range version of Noctua's NE-FD2 motor driver IC in order to
support 24V-based industrial applications. 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 Noctua’s trusted reliability and 6 years manufacturer’s warranty,
the NF-A14 industrialPPC is an ideal choice for highly demanding
applications that require superior flow rates and ultimate


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.

2000rpm industrialPPC version

Thanks to its elevated 2000rpm top speed, the NF-A14 industrialPPC-2000
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.

24V version

The industrialPPC 24V models use a dedicated wide input range version of
Noctua's NE-FD2 three-phase PWM motor driver IC. Supporting operating
voltages from 6 to 30V, these models are ideal for 24V-based industrial
applications and voltage- or PWM-based speed control.

Lower speed and noise levels in 12V PC environments

While the industrialPPC 24V model has been designed with 24V industrial
applications in mind, it runs at a maximum speed of around 1100rpm in
12V PC environments and can be slowed down further via PWM, thus
combining industrialPPC features and design with Noctua’s signature

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.

Certified IP67 water- and dust protection

The motor and PCB of the IP67 version are completely cast in a special,
highly heat conductive resin that combines thoroughgoing protection and
effective motor heat dissipation. Complying with the ingress protection
rating IP67, this fan is not only fully dust tight but also completely
waterproof up to 1m water depth.

Fibre-glass reinforced polyamide construction

Both the impeller and the frame of Noctua’s 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 Noctua’s standard fibre-glass reinforced PBT fans.

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.

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.

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

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

SSO2 Bearing

The NF-A14 industrialPPC 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 industrialPPC 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 industrialPPC
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 industrialPPC features an
MTBF rating of more than 150.000 hours and comes with a full 6-year
manufacturer’s warranty.

Customisable for industry clients

For industry clients, various features, certificates, packaging options
and accessories can be customised on requests. For example, we can
provide 24V versions, different connectors and speeds, different cable
length or UL and TÜV certification. Please feel free to contact us for
