Airport fuel depot managers face non-negotiable safety risks if jet fuel retains tiny water droplets after coalescing treatment. Even trace moisture mixed in aviation kerosene may trigger aircraft engine flameout during flight, which makes reliable separator cartridge an indispensable safety component. Many low-cost separator filter lose hydrophobic capacity within 1–2 months, failing to block re-entrained liquid mist after coalescer cartridge processing. As a listed filter manufacturer with 15 years of aviation filtration experience, LEFILTER CM series dedicated separator filter cartridge strictly follows EI1581 global aviation fuel standard, adopting thermally bonded permanent PTFE coated separator filter element. This aviation-grade separator cartridge filter perfectly matches all CA series coalescer filter cartridge, forming two-stage jet fuel purification system, different from ordinary natural gas filter separation consumables used for pipeline gas. When matched with FG gas filter element as pre-interception, the full filtration train removes solid particles and emulsified water completely. View all aviation & gas filtration parts via gas filter element, industrial water RO membrane and Ultrafiltration membrane module are listed on Water Filter Element.
Working Mechanism Of CM Aviation Separator Cartridge
Jet fuel containing residual micro water mist flows through CM separator filter cartridge after passing CA coalescer cartridge. The integral PTFE hydrophobic layer on stainless steel mesh of separator filter element repels all water droplets completely, only allowing clean anhydrous kerosene to penetrate the filter layer. Trapped liquid aggregates on the outer surface of this separator cartridge filter and slides down to the settling tank by gravity, eliminating liquid carryover risk even under maximum fuel flow rate. Unlike general separator filter for gas filter cartridge, aviation-specified mesh density balances low flow resistance and ultra-high water blocking efficiency, fully meeting strict airport fuel quality inspection standards.

FAQ For Aviation Fuel Operators
Q1 Must CM separator filter element match CA coalescer?
A1 Yes, single-stage separator cartridge filter cannot reach aviation fuel water removal standard without front CA coalescer cartridge.
Q2 Can CM replace original Facet aviation filter parts?
A2 Unified thread, length and sealing size, direct replacement without equipment transformation.
Q3 What medium is CM separator filter suitable for?
A1 Jet A / Jet A1 / JP8 aviation kerosene, light hydrocarbon fuel, not for raw natural gas filter pipeline gas.
Q4 What’s the service cycle of PTFE coating on separator cartridge filter?
A4 Full service life without peeling under normal airport fuel station operating conditions.
