Abstract:
A reliable, cost effective system and method are disclosed for exchanging fluid-filtration filters associated with electrical discharge machines (EDMs) and other applications. The basic system comprises a housing to receive the filter, the housing having a top that opens and a bottom cap with an interior inlet fitting coupled to a supply line carrying fluid to be filtered. A pair of opposing swing arms, each having one end pivotally connected to a filter cabinet or other suitable base and another end pivotally connected to an opposing side of the housing, facilitate a first state, wherein the housing and filter are vertically oriented with the bottom opening of the filter sealed against the fitting for filtering operation, and a second state, wherein the housing is pivoted such that the top is oriented downwardly allowing the filter to disengage from the fitting and slide out of the housing.
