The assembly, in an embodiment, includes a housing defining an inner space. The housing enables a flow from an oil supply to an oil inlet of the housing. The assembly also includes an inlet pump that enables flow from the oil supply to the oil inlet. The housing's inner space is configured so that the oil and foam formed on the oil's surface and are released to an oil outlet of the housing. The housing is configured to output gas from the inner space of the housing, thereby removing water from oil. ## Claims ### Claim 1 An assembly usable to facilitate a separation and removal of water from an oil of an oil supply, wherein the assembly comprises: a housing defining an inner space, wherein the housing comprises an oil inlet configured to receive an oil that flows from an oil supply through an oil inlet tube to the oil inlet of the housing;
