The Oil Boss skimmer keeps coolant free of oil and extends tool and coolant life. The Oil Boss coolant skimmer pumps oil-laden fluid from the sump through its chip-blocking SurfaceSucker. From there, it passes through coalescing media that separates the oil from the coolant. Clean coolant returns to the sump. Skimmed oil is held in a containment area until the operator easily removes the oil via the discharge tap.
