ABSTRACT:
A system for filtering electric discharge machine dielectric fluid wherein the filtering apparatus is mounted on a moveable platform and attached to the electric discharge machine that needs it's dielectric fluid filtered of foreign matter. The filter system has a plurality of filter casings connected in parallel by each casings inlet and outlet fittings. Each filter casing consists of a tank having a removable lid and a replaceable filter element inside the tank. The fluid flows into the filter tank, through the filter element, into a perforated tube and out of the filter tank into the interconnecting piping system. The filter system is separate from the reserve dielectric fluid tank of the electric discharge machine and can be operated either with the reserve tank system or connected directly to the electric discharge machine.
