Designed for the most demanding industrial applications that need improved cooling performance and more advanced protection, the Noctua NF-A14 industrialPPC (Protected Performance Refrigeration) is a robust, high-speed version of the company's award-winning model. Thanks to the incredible aerodynamic efficiency of the NF-A14's design and the use of a new three-phase motor, the industrial version PCP offers superior air flow and pressure capacity, while maintaining low noise and energy consumption levels compared to high speed fans. While its construction in fiberglass reinforced polyamide and its certified protection against water and dust make the NF-A14 industrialPPC suitable for use in extreme environments, the renowned SSO2 bearings guarantee an average life time between failures ( MTBF) of more than 150,000 hours. This product has the proven reliability of Noctua and a 6-year manufacturer's warranty, so the NF-A14 industrialPPC is the ideal choice for the most demanding applications that need superior airflows and maximum reliability.
Award-winning NF-A14 design
After receiving more than 100 awards and recommendations from the international press, the NF-A14 of Noctua has become the best and safest choice for 140 mm refrigeration needs. Its recognized efficiency has convinced tens of thousands of customers worldwide.
Industrial version 2000 rpm PCP
Thanks to its high maximum speed of 2000 rpm, the NF-A14 industrialPPC-2000 offers higher performance compared to the 1500 rpm version. The robust polyamide construction, characteristic of the industrial PCP series, and advanced protection features make the fan ideal for the most demanding industrial applications.
Three phase motor design
While most axial fans use single-phase motors with 4 slots, Noctua industrial PC fans feature a three-phase design with 6 slots, which offers a smoother transition between slots and thus allows even smoother operation and silent, a reduction of vibrations and an unprecedented energy efficiency.
Improved energy efficiency
While the standard NF-A14 is one of the most efficient 140 mm and 1500 rpm fans, the industrial version PCP with three-phase motor offers a 10% reduction in energy consumption when compared to the 2000 rpm version.
Fiberglass reinforced polyamide construction
Both the rotor and the Noctua industrial PC fan frame are entirely made of fiberglass reinforced polyamide. This makes the fans even more robust and resistant than standard fiberglass reinforced PBT fans.
Certified IP67 protection against water and dust
The motor and the printed circuit board (PCB) of the IP67 version are completely covered by a special highly conductive resin that combines perfect protection with an effective heat dissipation of the motor. Complying with the requirements of the IP67 protection rating, this fan is not only made of dustproof, but also completely waterproof to a depth of 1 m.
Flow Acceleration Channels
The rotor of the NF-A14 has Flow Acceleration Channels on the suction side. By increasing the speed of the air flow in the crucial outer regions of the blades, this measure reduces the separation of the flow on the suction side, resulting in greater efficiency and lower vortex noise.
Frame with AAO
The frames with AAO (Advanced Acoustic Optimization) from Noctua have integrated anti-vibration pads, in addition to patented Noctua technologies such as Stepped Inlet Design (step entry design) and Inner Surface Microstructures (internal surface microstructures) that improve efficiency of fan noise performance.
Stepped Inlet Design
The Noctua Stepped Inlet Design adds turbulence to the inflow to facilitate the transition from laminar flow to turbulent flow, which reduces the tonal input noise, improves the adhesion of the flow and increases the flow suction capacity, especially in confined space environments.
With the ends of the fan blades colliding with the boundary layer created by the Inner Surface Microstructures (internal surface microstructures), the separation of the flow from the suction side of the blades decreases significantly, resulting in a noise of passage between the lower blades, better air flow and greater pressure efficiency.
Integrated anti-vibration pads
The integrated anti-vibration pads, made of extra soft silicone, minimize the transmission of smaller vibrations, while maintaining compatibility with all standard mounting systems and fan clips used in heatsinks.
The NF-A14 industrialPPC has the second generation, even more optimized, of the renowned and effective Noctua SSO bearings. With SSO2, the rear magnet is placed closer to the axle to provide better stability, precision and durability.
To ensure the highest possible degree of manufacturing precision, minimal tolerance and excellent long-term stability, the NF-A14 industrialPPC boasts a milled CNC bearing made entirely of brass.
PWM IC of own design with SCD
By providing fully automatic PWM speed control, the NF-A14 industrialPPC uses the NE-FD2 PWM IC, specially designed by Noctua for three-phase motors. The NE-FD2 integrates Noctua's patented Soft Switching Unit (SCD) technology, which suppresses PWM switching noises and thus makes the fan quieter at lower speeds.
