ST609FB‑5 Large‑Flow Separator Filter Element For Bulk Fuel Terminal
ST609FB‑5 large‑flow separator filter element, ST‑series high‑capacity hydrophobic separator cartridge, second‑stage separation component designed for high‑volume aviation fuel coalescer‑separator vessels at bulk fuel storage terminals.
Product Introduction
Oil Filtration Machine manufactures large‑capacity Coalescer Filter and supporting separator consumables for bulk aviation fuel storage terminals. ST609FB‑5 separator filter element is ST‑series large‑flow hydrophobic separator cartridge. It is designed for high‑volume aviation fuel and light‑hydrocarbon filter‑separator vessels, acting as critical second‑stage water‑repellent component after upstream coalescer cartridge. Bulk fuel terminals often handle huge instantaneous flow rate, separator structural strength and stable hydrophobic performance are very important to avoid water carry‑over risk.
High‑performance specially‑treated hydrophobic composite glass‑fiber media is adopted. After upstream coalescer merges micro water droplets into large droplets, mixed fuel flows to inner side of separator cartridge. Hydrophobic media blocks water droplets, water flows back to settling compartment under gravity, while clean hydrocarbon fuel passes outward to downstream pipeline. Heavy‑duty double‑side metal cage improves mechanical stability under large‑flow and fluctuating pressure working conditions.
Each ST‑series separator completes ISO 2941 collapse‑burst test and strict hydrophobic‑performance inspection before shipment. ST609FB‑5 cannot work alone; must be matched with corresponding CA‑ / CM‑series coalescer filter element. View category page: Separator Filter Element.
Frequently Asked Questions
Q: What is the difference between ST‑series and SM‑series separator?
A: ST‑series is optimized for higher flow‑rate scenarios, more suitable for bulk fuel terminal large‑volume processing conditions.
Q: Can separator cartridge be cleaned and reused after contamination?
A: Once hydrophobic property degrades due to contamination, it belongs to consumable spare part, disposable replacement is recommended.
Q: What is typical failure symptom of aged separator element?
A: Continuous water carry‑over phenomenon, water content of outlet fuel exceeds technical specification limit.
Q: When should we replace full coalescer‑separator set?
A: Replace coalescer and separator together when system differential pressure reaches 12‑15 psi.
