SO‑633VA5 Velcon‑Equivalent Aviation Separator Filter Element
SO‑633VA5 separator filter element, Velcon‑equivalent hydrophobic separator cartridge, works with I‑series coalescer for aviation fuel terminal coalescer‑separator vessel.
Product Introduction
Oil Filtration Machine provides aviation‑grade Coalescer Filter and separator cartridges for airport fuel depots. SO‑633VA5 separator filter element belongs to Velcon SO‑series hydrophobic separator cartridge. It is widely used in airport aviation fuel terminal, matched with I‑series coalescer filter cartridge as secondary‑stage barrier inside Velcon‑style filter‑separator vessel, to block coalesced water droplets and protect downstream fuel quality.
Special water‑repellent composite media is adopted. Flow direction is outside‑to‑inside. Fuel carrying large coalesced water droplets flows onto cartridge outer face. Hydrophobic media rejects water droplets but allows hydrocarbon fuel to pass through. Rejected water accumulates and sinks into housing bottom sump for regular draining. Reinforced end‑cap and inner core guarantee stable performance under cyclic pressure variation.
Inspection standard refers to API‑1581 aviation fuel filter criteria. SO‑633VA5 cannot be used without matched I‑series coalescer filter cartridge. Visit: Separator Filter Element.
Frequently Asked Questions
Q: Which coalescer filter shall match SO‑633VA5?
A: Corresponding I‑series Velcon‑type coalescer filter cartridge shall be installed as upstream component.
Q: What test criteria apply for this aviation separator?
A: Performance inspection follows API‑1581 aviation filter performance criteria.
Q: What is core working principle?
A: Hydrophobic media repels water droplets while letting clean hydrocarbon fuel pass through to realize liquid‑liquid separation.
Q: When to replace full filter set?
A: Replace coalescer and separator together when housing differential pressure continuously rises to 12‑15 psi.
