In prevention of two different kinds of fluid from intermixing caused by internal leakage, KAORI precisely designed the D Series solution with the double-stacked plates, to eliminate the possibility of cross contamination. The unique air gap is created between the two plates. Once the internal leakage occurs, the 2nd plate becomes the shield to keep the liquid stay and flow on the same channel through the air gap. Meanwhile, vent holes outside the plate will seep out the liquid as an indication of leakage.
