NV-AA1-12

Do 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.

The 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.

Following 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.

In 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.
