Replacement Facet ST424FB-5 Fuel Separator Filter Element

Product Overview

Facet ST424FB-5 belongs to the classic ST-series FB heavy-duty separator lineup, optimized for stable operation under medium-large flow and slightly high impurity working conditions. Different from FA standard type and FC precision type separators, FB-type elements adopt enhanced fiber structure and optimized pore distribution, balancing high flow throughput and reliable water blocking performance.

Matched with front-stage coalescing filter elements, ST424FB-5 undertakes the final fuel-water separation procedure. With permanent hydrophobic modification treatment, the filter media never absorbs water and completely blocks water penetration, ensuring only dry, clean jet fuel and diesel pass through. The integral epoxy sealing and reinforced internal support structure effectively resist pressure fluctuation and fluid impact, avoiding media deformation and bypass leakage during long-cycle 24/7 continuous operation, greatly improving finished fuel qualification rate and downstream equipment safety.

Working Principle

The Facet ST424FB-5 separator adopts professional hydrophobic water-repellent separation principle, completely different from coalescing filters:

1. After primary coalescence treatment, fuel mixed with aggregated large water droplets flows from inside to outside through the separator element.

2. The specially modified hydrophobic glass fiber media produces absolute repulsion effect on water droplets, thoroughly blocking all free water without penetration.

3. Qualified dry fuel smoothly passes through the filter layer and flows out of the equipment, realizing fuel purification.

4. Blocked water droplets continuously accumulate on the filter surface, merge into large water masses, and settle to the bottom sump by gravity, completing thorough fuel-water separation.

Product Features
