Abstract
A cylindrical oil contamination collector for removal of ultra-fine particulate includes a rectangular and continuous length of single-sided, corrugated, phenolic coated paper overlaid with three rectangular electrodes affixed thereto in a spaced-apart, side-by-side arrangement. Two of the electrodes are electrode grounds and the other electrode is a high voltage electrode. The phenolic coated paper is spiral-wound into a continuous spiral with at least one of the three rectangular electrodes sandwiched between adjacent, overlapping turns of the spiral-wound phenolic coated paper.
