Function
The maintenance units NWE are used for the preparation of compressed
air. They consist of the filter regulator unit NFR and the lubricator unit
NOE.
The incoming compressed air is filtered and condensate is separated. The
filter control valve regulates the supplied compressed air to the operating
pressure set on the pressure regulator and compensates any pressure
fluctuations.
The lubricator unit adds an oil mist to the filtered compressed air to lubri-
cate the pneumatic vibrators supplied with it. The oil quantity can be ad-
justed with the dosing screw.
