Separator systems play a crucial role in removing contaminants such as oils and other light liquids from water, particularly in industries where water pollution can be a significant concern. These systems are classified according to their size (NS) based on the EN 858 part 2 standard, and are essential for industries like car washes, workshops, fuel stations, vehicle fleets, and hazardous goods stores.

GRAF proposes 2 types of Separators - Coalescence Separators (Class I) for reducing oil content in water to less than 5 mg/l. Organic & Fuel Separators (Class II), achieving oil levels of less than 100 mg/l.
