The AMSOIL Dahl Fuel Filter/Water Separator removes water and solid contaminants from fuel before it reaches the fuel pump and injection system.

Water and solid contaminants reduce the effectiveness of fuel's lubricative coating on high precision injection components. If this protection continues to decrease, the results can include wear, erosion, surface pitting and eventual ly loss of pressure.

Many existing fuel filters are not designed to remove significant amounts of water. They are designed to simply filter in only one step. To accomplish this, they must be porous enough to allow a sufficient volume of flow. This limits its filtering ability to between only 10 and 30 microns. Using a tighter media would plug up too quickly and the filter would need frequent element changes.

The AMSOIL Dahl system has none of these shortcomings. Its dual chamber 3-stage fuel filter/water separators provide efficient water separation and contaminant filtration. The unique patented depressurizer cone spreads the flow of the fuel. With more area to flow over, there is greater separation of water and dirt from the fuel.

The AMSOIL Dahl system has less mechanical flow resistance than other separators, because the fuel only changes direction twice. The AMSOIL Dahl system removes virtually 100 percent of the water and most of the solid contaminants in the fuel.

The AMSOIL Dahl system prolongs system life by eliminating pump and injector overhauls caused by water-contaminated fuel. It also reduces downtime spent repairing the fuel pump and injection system. The loss of income from only a few hours of downtime is greater than the cost of an AMSOIL Dahl system.

The AMSOIL Dahl system includes a reverse flow valve that holds the prime in the fuel system by not allowing flow back to the tank during shut down. It also helps eliminate air entrapment because the inlet and outlet ports are at the top of the unit. The fuel changes direction only twice, creating less flow resistance and allowing longer pump and element life.

Most solid contaminants are removed by the depressurizer cone in the bowl before reaching the filter element, which has extra media. These characteristics allow the element to last up to 40,000 miles under normal conditions.

How The AMSOIL / DAHL System Works

 

1.      The contaminated fuel enters the inlet port.

2.      The T-Bolt redirects the fuel downward through the centerpipe.

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 the bowl.

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.
