ABSTRACT:
A filter assembly for an electrostatic filter for removing solid contaminants in parts-washing solvents and other fluids is disclosed. The filter assembly provides a back flushable filter pack for continual use. When the flow of cleaned fluid slows, a simple procedure of back flushing will give user full flow and complete filtration again. This provides continual use by cleaning clogged porous filter media without the expense of a new filter pack each time it clogs with contaminant. The filter pack provides a stacked array of alternatingly charged electrode plates sandwiched between porous filter media. Appropriate electrical connections are disclosed and an electric monitoring circuit for monitoring the condition of the electrostatic filter is also disclosed.
