Abstract:
An electrostatic filtration cartridge unit (100) for removing contaminants from a dielectric fluid and comprising : • at least one set m of conductive metal plates (122-1 to 122-6); • at least one set n of conductive metal plates (126-1 to 126-5); • the plates of the m and n sets being interleaved one with another and the plates of the m and n sets respectively being interconnected by conductive meta l connector portions (122-CP1 to 122-CP5; 126-CP1 to 126-CP4) attached fast thereto; and • a filter pad (128) disposed between each of the interleaved conductive meta l plates. The unit fits in a cartridge housing (102) which is openable and reclosable to enable replacement of cartridge units.
