Sound-optimised blade geometry and profile: The NF-R8 is the first fan employing a novel 80mm rotor which was developed by the Austrian Institute for Heat-Transmission and Fan Technology (sterreichisches Institut fr Wrmebertragung und Ventilatorentechnik, IWV). Thanks to the special optimisation of the blade geometry towards ultra low noise application, the NF-R8 is up to 10% more quiet than current high-end fans at the same flow rate.

Self-stabilising oil-pressure bearing (SSO-Bearing): The NF-R8 series are equipped with a magnetically centred, self lubricating oil-pressure bearing that provides a new level of quietness and long-term stability.
