Highly optimised impeller with Bevelled Blade Tips
Thanks to its further refined blade geometry with extended leading edges and Bevelled Blade Tips, the NF-S12B achieves up to 10% more airflow and static pressure than its much acclaimed predecessor at the same noise level.

3 speed settings for full flexibility

Providing 1200, 900 and 600 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adapters, the FLX (Flexibility) version can be fine-tuned for superior airflow or maximum quietness.
