TJ9 De Laval Oil Purifiers continuously remove and discharge water while removing the dirt as well. And water is the real trouble maker as often as. not. In turbine lubricating systems, ' for instance, condensate water in the oil leads to the formation of sludge, and sludge, of couree, is well recognized as the source of trouble in turbine lubrication systems. Diesel oils, too, should be kept dry if the for mation of emulsions is' to be avoided. Purifica tion by centrifugal force is of more than ordinary importance with the heavier types, of diesel lubricating oil. Centrifugal force applied in the De Laval bowl gives equally positive protection against dirt . . . keeps the oil clean and in "like-new" condition. In short, De Laval Oil Purifiers afford tur bines and diesel engines full protection against the principal causes of lubrication failure, by removing the impurities that contaminate oil in service.
