WAL - Liquid Filter Separator (Three Stage Horizontal) Engineered Products and Packages

The WAL Series Liquid Filter Separator provides water coalescing and filtration of hydrocarbon fuels, such as jet fuel, kerosene, diesel, gasoline and similar liquids, where greater efficiency of water removal is required. The WAL is a three-stage horizontal liquid filter separator. The first stage removes particulate and coalesces the water contaminant, while the second stage separates water droplets from the fuel. The third stage is an extra safeguard to absorb any remaining water.
