Abstract

An electrostatic filter for removing contaminants from a dielectric fluid when the filter comprises a plurality of electrically conductive plates positioned in a housing and having filter media disposed between the plates so that during the operation of the filters, fluid flows axially through the media between the electrode plates and into a central recovery zone and is discharged from the filter. A replaceable filter cartridge, a method for removing contaminants from a dielectric fluid using the filter, a filtration system for removing both water and other contaminants from a dielectric fluid using the filter in combination with a water-removal filter and a system for maintaining a supply of filter dielectric fluid for a dielectric fluid user on a continuous basis are disclosed.
