Noctua NV-AA1-12 -Ilmavirran vahvistin
The nv-aa1-12 is an airflow amplifier for nf-a12x25 120mm fans that is ideal for boosting their performance in desk and room ventilation applications. Thanks to a three-way airflow amplification system that combines helix energy recovery, progressive flow acceleration, and venturi-effect volume enhancement, the nv-aa1 enables these fans to create a strong, focused beam of air while maintaining exceptional quietness of operation. As such, the nv-aa1-12 is both perfect for situations where fans are required to blow air across a room or other bigger spaces, but also for applications with smaller working distances like typical desk or ambient fans, where the amplification effect of the nv-aa1-12 makes it possible to achieve the same ventilation performance at lower fan speeds and noise levels.three-way airflow amplification systemthe nv-aa1-12 leverages a sophisticated three-step procedure to significantly boost the nf-a12x25’s performance in ambient ventilation applications. Through the combination of helix energy recovery, progressive flow acceleration, and venturi-effect volume enhancement, the nv-aa1-12 enables these fans to produce a strong, focused beam of air even when they run at near-inaudible noise levels.helix energy recoverythe air that comes out of an axial fan has a high amount of rotational energy, which results in a helix-shaped flow path. The nv-aa1-12 recovers this rotational energy and uses it to accelerate the airflow. With the inside shape of the nv-aa1’s funnel carefully fine-tuned to the helix structure produced by the nf-a12x25 fan, it achieves an extremely high rate of energy recovery.progressive flow accelerationfollowing the principle of mass continuity, a fluid’s speed increases when it’s forced through a reduced cross-sectional area, so when the air is driven through the nv-aa1’s progressively narrowing funnel, air speed increases continuously until it reaches maximum velocity at the outlet.venturi-effect volume enhancementin accord with the principle of conservation of energy, air pressure must decrease as air velocity increases (bernoulli’s principle). This reduction in pressure that occurs when a fluid flows through a constriction, the so-called venturi-effect, creates a suction force at the outlet, which draws in additional air from the sides and through the cuts of the nv-aa1’s funnel, thereby enhancing the airflow volume.ideal in combination with nv-fm1do you require strong but quiet airflow on your desk or somewhere in your room? Combine the nv-aa1-12 and nf-a12x25 fan with the nv-fm1 multi-purpose pivoting fan mount! With its solid metal construction and flexible mounting options, the nv-fm1 is the ideal solution for putting or fixing a fan literally anywhere – from your desk or shelf to your walls or ceilings.easy installationinstalling the nv-aa1 couldn’t be easier: first, remove the fan’s pre-installed anti-vibration pads on the outlet side of the fan and replace them with the na-avg1 anti-vibration gasket that came with the fan so that there will be no gap between the fan and the nv-aa1. Then, screw-fix the nv-aa1 to the fan’s mounting holes using the supplied screws.optimised for nf-a12x25the nv-aa1-12’s aerodynamic design has been created and carefully fine-tuned for use with noctua’s nf-a12x25 series fans. For home applications, the 5v pwm models with usb power adaptor cables can easily be run off power banks or standard usb power supplies. The nv-ps1 power supply is available for powering 12v models.
