DAHL / BALDWIN - Fuel/water separator ADVANTAGES DAHL / BALDWIN patented fuel/water separator, works using a 3-stage separator system. Fuel flows straight from the upper part of the separator to the bowl, so that air bubbles are not entrapped in the system and flow resistance is reduced. The depressurizer cone separates 100% of the water and 80% of the solid contaminants. The filter element of the separator, which can be made with paper of 30, 10 or 2 microns, holds the rest of the solid particles before they reach the fuel pump. The paper of the filter element is impregnated with resin, so that can hold all moisture, which may be contained in the fuel. DAHL fuerl/water separator includes a reverse flow valve which does not allow fuel to flow back to the track during shut-down.   FLOW DIAGRAM 1. The contaminated fuel enters the inlet port 2. The T-Bolt redirects the fuel downward through the centertube 3. Fuel flows through the reverse flow valve 4. Fuel flow is spread by the depressurizer cone 5. As fuel is discharged from the depressurizer cone, 80% of contaminant separation takes place. Most of the solid particles and water settle into the quiet zone of the bowl 6. As the fuel rises upward, any remaining minute water droplets coalesce on cone, baffle and bowl surfaces. Droplet size and weight gradually increase causing downward flow into sump 7. Fuel is filtered completely by the element. The clean fuel then continues upward through the outlet port and on to the pump and injection system
