Facet SS640FF-5 Top-Grade FF Ultra-Dry Fuel Water Separator Filter

The SS640FF-5 FF top-grade separator defines the highest standard of secondary fuel-water separation. Different from FE single-layer precision filtration, FF-grade elements adopt dual-density composite fiber structure, achieving deeper interception of nano-scale emulsified water and ultra-fine floating particles. It completely solves common high-end system pain points such as slight fuel turbidity, trace residual water and secondary emulsification under variable flow conditions.

As an upgraded SS-series model, SS640FF-5 features optimized fiber solidification and high-temperature hydrophobic curing technology, providing exceptional anti-aging, anti-scouring and anti-deformation performance compared with ordinary ST-series filters. The fully sealed integral end cap structure eliminates any filtration bypass or dead zone, while the reinforced internal skeleton ensures stable precision output even under long-term high-pressure fluctuation and 24/7 continuous operation. It is the ultimate purification choice for high-standard fuel systems pursuing zero water residue.

Working Principle

SS640FF-5 adopts Facet’s flagship dual-gradient ultra-dry hydrophobic separation technology:

1. Post-coalescence fuel containing nano-level emulsified water and micro impurities flows radially from inside to outside.

2. The first dense fiber layer blocks large water droplets and coarse particles; the second ultra-fine FF-grade layer intercepts residual micro-water molecules.

3. Only ultra-dry, high-purity qualified jet fuel and light hydrocarbon fuel pass through the media smoothly.

4. Isolated micro-water accumulates rapidly, merges into macroscopic water masses, and settles by gravity to achieve zero-residue fuel drying effect.
