  • Double filtration for purifying coolant-lubricant liquids
    Publication number: 20030015482
    Abstract: A method for purifying coolant-lubricant oils which continuously circulate in metalworking installations and are purified by a vacuum filter assembly (13). The basic filtration takes place in the main stream, while additional purification by membrane filtration takes place in a secondary stream. The resulting method has a high filtration capacity and ensures an optimal purification of the coolant-lubricant liquid.
