The use of an oil skimmer in the machine shop setting holds multiple benefits. Removing the oil from a machine coolant tank will begin some aesthetic benefits like cutting down on the amount of the smoke created from the cutting tool coming into the contact with oil loaded coolant. When a machine is shut down for the weekend, the oil has a chance to come to the surface of the coolant tank. Bacteria that are living in the coolant tank use the dissolved oxygen in the coolant mix, a procedure that is increasing by having a layer of oil on the surface. It allows odor-causing anaerobic bacteria to thrive and giving off that familiar “rotten egg” smell.
