FIELD: lubricants. SUBSTANCE: invention relates to clarification of lubricating fluids containing suspended impurities and foreign inclusions and can be applied at metalworking enterprises having centralized treatment system. Assembly includes at least one centralized lubricating fluid system having accumulating tank, combination of full-flow lubricating fluid clarifiers, lubricating fluid preparation and lubricating fluid composition correction module, and additional group of lubricating fluid clarifiers connected over pumps to centralized system and including flotation machine provided with oil scraping drum, magnetic separator, emergency three-phase (oil-liquid-solid precipitate) separator constructed in the form of centrifugal separator mounted according to by-pass scheme in relation to magnetic separator and flotation machine, and pump. Outlet of additional group of clarifiers is connected to one or more centralized systems and equipment of additional group is made such as to ensure lubricating fluid clarification productivity within a range of 1 to 10% of the summary productivity of centralized systems connected. EFFECT: enabled continuous clarification of lubricating fluids. 5 cl, 2 dwg
