How does the puraDYN® bypass oil filtration system work?
In Stage One, oil enters the unit from a bypass oil pressure line, typically from the oil pressure sending unit or an oil galley plug near the full flow filter. The oil enters the puraDYN® system through a metering jet that limits the flow between 6 to 8 gallons per hour (22 to 30 liters per hour), into a 100% unbleached long-strand natural cotton fiber filled filter element. The solid contaminants, such as carbon, sludge, soot, varnish, dirt, silica, wear metal particles and other foreign matter, are trapped down to 1 micron in size. In Stage Two the oil, free of solid contaminants, travels into the heated evaporation chamber flowing over a diffuser plate. The oil pressure has dissipated to atmospheric pressure causing the oil to flow in a thin film over the floor and walls of the heated evaporation chamber. The temperature in the evaporation chamber is approximately 200° F but may vary slightly depending on the outside ambient temperature. The heat causes liquid contaminants like fue
