ABSTRACT:
An electrostatic filter for non-conductive liquids including an electrically conductive cylindrical housing having a fluid inlet at a first end portion thereof and a fluid outlet at a second end portion thereof with an easily removable filter cartridge disposed in the housing between the fluid inlet and outlet. The filter cartridge is made up of concentric spaced electrically conductive tubes having filter members disposed in the space between the tubes with an opposite electric charge provided to each adjacent tube. The non-conductive fluid passes through the resulting electric charged field such that positive charged particulate migrate to a negative plate and negative charged particulate migrate to a positive plate with no discrimination as to the type or size of particulate.
