Below is a list of Oil Centrifuge manufacturers from St. Croix Falls, Wisconsin. Oil centrifuges are devices designed predominantly for the filtration and separation of contaminants suspended in oils. Some such centrifuges may be used in instances where oil is the contaminant, but more often industries rely on these devices to clarify industrial, edible and hydraulic oils that may carry undesirable solid, gaseous or liquid materials as a result of extraction or continued processing. This clarification is achieved by the application of the sedimentation principle.
