Facet SS618FB-5 Long-Body Fuel Water Separator Replacement Filter

The Facet SS618FB-5 belongs to the SS-series long-body FB heavy-duty separator lineup, featuring longer effective filtration depth compared to conventional short and medium-sized filter elements. The extended filter area significantly improves flow balance and overall dirt holding capacity, effectively reducing clogging frequency during long-cycle continuous operation. Benefiting from SS-series upgraded synthetic fiber formulation, this element delivers better chemical stability, anti-aging performance and pressure fluctuation resistance than standard ST-series counterparts.

With permanent hydrophobic treatment on the entire filter media, SS618FB-5 maintains stable water-repellent capability without water absorption or performance decay under long-term fuel scouring. The integral epoxy sealing design eliminates bypass leakage, while the reinforced inner support tube prevents media deformation and collapse under high differential pressure. Balancing large flow throughput and heavy-duty filtration performance, it is widely adopted in mainstream two-stage fuel coalescence-separation systems.

Working Principle

SS618FB-5 operates based on Facet’s proven inside-out hydrophobic separation technology:

1. Post-coalescence fuel carrying large water droplets and fine impurities flows radially from inner to outer layers.

2. High-strength FB-grade hydrophobic fiber layer completely blocks free water and micro water droplets, allowing zero water penetration.

3. Only dry, clean and qualified fuel media passes through the filter smoothly.

4. Trapped water accumulates on the outer surface, merges into large water masses, and settles into the tank bottom by gravity to achieve thorough fuel-water separation.
