The Fluid Dynamic Bearing comes with an oil capsule that avoids lubricant leakage. Thus this bearing is as quiet as a sleeve bearing but comes with a significantly higher service life.

The impeller was designed with a focus on minimizing the noise level yet delivering the desired airflow and pressure.
