ABSTRACT:
A coolant filter for use in filtering a coolant solution which flows through the coolant filter includes a filter housing assembly which is made up of an outer housing which is crimped to a nutplate which defines an internally threaded flow outlet. A generally cylindrical filter element is positioned inside of the filter housing assembly and a first endplate is bonded to the end of the filter element which is adjacent to the nutplate. A second endplate is bonded to the opposite end of the filter element and helps to define an interior space within the filter element. A supply of supplemental coolant additive is contained within an osmotic film enclosure which is positioned within the interior space. The osmotic film enclosure provides a slow release mechanism for controlling the rate of release of the supplemental coolant additive into the coolant solution. In one embodiment of the present invention, the slow release mechanism includes a diffusion tube which defines a diffusion orifice.
