HOW DOES THE pura DYN ® BY-PASS OIL FILTRATION SYSTEM (puraDYN ® System) WORK?
A. In Stage One , oil enters the unit from a by-pass oil pressure line, typically from the oil pressure sending unit or an oil galley plug near the full flow filter. The oil enters the pura DYN ® System through a metering jet that limits the flow to 3 to 6 gallons per hour (11 to 23 liters), depending upon the pura DYN ® System’s size, into the hydraulically compressed 100% long strand unbleached natural cotton filter element. The solid contaminants, such as carbon, gum, sludge, fuel soot, varnish, wear metal particles, dirt and other foreign matter, are trapped down to the ½ to 1 micron in size. In Stage Two the oil, free of solid contaminants, flows into the heated evaporation chamber onto the 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 heat evaporation chamber at atmospheric pressure. The temperature in the evaporation chamber is approximately 200° F, and may vary slightly depending on
