  • Final separator
    Patent number: 10569205
    Abstract: A separator for a separator device, for example a final separator for a final separator device for separating water from a liquid such as oil and/or fuel, may include a filter body including at least one filter material through which the liquid can flow. The filter body may have a first side and a second side. A nanofibre layer may be disposed on the first side in at least one region. The nanofibre layer may be configured hydrophobic. According to an implementation, the nanofibre layer is treated to produce the hydrophobic property. The filter body may have a porosity on the first side that is smaller than on the second side.
