The NV-AA1-12 is an airflow amplifier for NF-A12x25 120-mm fans, ideal for boosting performance in desk and room ventilation applications. Thanks to a three-way airflow amplification system that combines helix energy recovery, progressive flow acceleration and a Venturi effect-based volume enhancement, the NV-AA1 enables these fans to produce a strong, focused stream of air while maintaining exceptionally quiet operation. The NV-AA1-12 is therefore not only the perfect solution when it comes to blowing air over across a room or other larger spaces, but also for applications with shorter working distances like typical desk fans, where the boost effect of the NV-AA1-12 enables the same ventilation performance to be achieved at lower speeds and noise levels. https://elecena.pl/product/27803743/nv-aa1-12-noctua-nv-aa1-12-airflow-amplifier 2025-02-06 https://elecena.pl/product/27803743/nv-aa1-12-noctua-nv-aa1-12-airflow-amplifier 2025-10-10
