Abstract
The present invention is an apparatus and method for filtering particulate matter from dielectric fluids, and for maintaining and monitoring of the purity of said fluids. The invention operates by imparting an electrostatic charge, via a pair of convoluted perforated oppositely charged electrodes, to the particulate contaminates contained in the fluid. The positive electrodes and negative electrodes are each unitary and in combination with a filter media form a unitary cartridge which is removable and replaceable within the apparatus. A microcontroller may be provided to monitor, analyze and report certain parameters of the fluid to be filtered.
