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.
