ST618FB‑5 Large‑Flow ST‑Series Separator Filter Element

Oil Filtration Machine provides large‑capacity Coalescer Filter and separator parts for bulk fuel terminals. ST618FB‑5 separator filter element is large‑flow Facet ST‑series hydrophobic separator cartridge. Designed for high‑volume aviation fuel and light‑hydrocarbon coalescer‑separator vessels, it serves as secondary‑stage water‑repellent component after upstream coalescer cartridge, widely used for large‑scale fuel storage terminal and refinery fuel‑processing workshop.

High‑performance hydrophobic composite glass‑fiber media is adopted. After coalescer merges micro water droplets into large drops, mixed fuel flows to inner side of separator cartridge. Hydrophobic media blocks water droplets, water flows back to settling compartment, clean fuel flows outward to downstream pipeline. Heavy‑duty double‑side metal cage improves mechanical strength under large‑flow fluctuating working condition.

Each ST‑series separator completes ISO 2941 collapse‑burst test and hydrophobic performance inspection. Must work together with matched upstream CA‑ / CM‑series coalescer filter element. Check page: Separator Filter Element.

Frequently Asked Questions

Q: What is characteristic for ST‑series separator compare with SM‑series?
A: ST‑series is optimized for larger flow rate, fit high‑volume fuel‑processing working condition.

Q: Can separator cartridge be cleaned and reused?
A: Once hydrophobic property degrades after contamination, it belongs to consumable part, disposable replacement is recommended.

Q: What failure symptom indicates separator performance drop?
A: Continuous water carry‑over, outlet fuel water content exceeds technical specification.

Q: What differential pressure trigger full‑set replacement?
A: Replace coalescer plus separator together when differential pressure reaches 12‑15 psi.
