Abstract
An apparatus for removing floating and subsurface contaminants from a machine tool coolant bath is disclosed. The apparatus comprises a floating skimmer for collecting floating contaminants from the surface of the bath connected to an oil trap having an imperforate shell with a fluid tight column extending below the interface. A return conduit and a positive displacement pump are in series with the skimmer and oil trap. A submersible pump is disposed in the bath near the bottom for collection of water and water density contaminants and is connected to a remote filter assembly having a housing and a removable filter element. The filter assembly and the oil trap are both accessible without affecting the operation of the machine.
