Greater Efficiency - Less Noise at Higher Airflow At low fan speed, the motor noise is key. A motor developed in Germany with a new alloy/lubricant combination reduced friction and noise.
Long Service Life 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.
Innovative Design Enables Quiet and Efficient Ventilation The innovative design of the fan blades improves the airflow and facilitates a highly efficient ventilation. The impeller was designed with a focus on minimzing the noise level yet delivering the desired airflow and pressure.
