A filtering device for fluids includes a filter housing (1) and a filter element (9) received in the filter housing. The filter element has an end cap (17) on at least one end. The end cap forms an enclosure for the corresponding end edge of the filtering material (23, 35) and is fixed on an element receiver (13) interacting with the bottom part (5) of the filter housing (1) to fix the position of the filter element (9) in its functional position. The element receiver forms a fluid path for the cleaned fluid exiting the hollow chamber (19) of the filter element (9). The element receiver (13) contains a valve arrangement (55) blocking the fluid path (35). A control device (79, 83) releasing the valve arrangement (55) in the functional position is on the end cap (17) of the filtering element (9). The end cap is fixed on the element receiver (13).

This disclosure provides for an improved electrostatic filtration system for removing contaminants from a dielectric fluid that overcomes arcing concerns, resistance burns and fluid flow concerns. The system has three major elements: an electrostatic filtration cartridge; an electrostatic filtration cartridge housing; and an electrostatic filtration system housing. It is within the electrostatic filtration cartridge where the apparatus and method for addressing the arcing concerns and fluid flow concerns reside. The electrostatic filtration cartridge includes at least one set of m conductive plates (m set) and at least one set of n conductive plates (n set). Within the sets (m set and n set) of conductive plates, the conductive plates are directly coupled by a series of conductive connecting portions. Each individual conductive plate includes a cutaway portion to avoid electrical contact between one set of conductive plates and an adjacent conductive connecting portion within another set of conductive plates.
