At low fan speed, the motor noise is key. A motor developed by professionals with alloy/lubricant combination reduced friction and noise. The fluid dynamic bearing features an oil capsule that avoids lubricant leakage. Thus this bearing is as quiet as a sleeve bearing but provides a significantly higher service life. The advanced design of the fan blades improves the airflow and facilitates a highly efficient ventilation. The impeller was designed with a focus on minimizing the noise level yet delivering the desired airflow and pressure.
