Genuine Standard Velcon I-614C5TB Coalescing Filter | 14-Inch Threaded Base Aviation Fuel Coalescer

LEFILTER high-precision interchangeableVelcon I-614C5TB coalescing filter element is a standard 14-inch aviation-grade coalescer cartridge engineered for Parker Velcon filter separator vessels. Fully compliant with EI 1581 6th Edition aviation filtration specifications, this threaded-base coalescer serves as the core first-stage filtration component for hydrocarbon fuel purification. Designed for inside-to-out flow operation, it reliably removes fine solid particulates, free water, and micron-sized emulsified water droplets from jet fuel, diesel, and gasoline. With strictly replicated dimensional parameters, epoxy bonding process, and hydrophilic fiberglass media, our I-614C5TB offers perfect drop-in compatibility with original Velcon housings, ensuring identical field performance and prolonged service cycles for aviation and industrial fuel handling systems.

The Velcon I-614C5TB belongs to the classic I-614 series coalescer lineup, widely recognized in global aviation fueling and bulk fuel terminal industries. Different from compact or heavy-duty oversized filter elements, this 14-inch standard-size coalescer balances stable flow throughput, excellent dirt holding capacity, and reliable water-oil separation efficiency for daily continuous fuel purification. It solves common operational problems such as fuel clouding, residual moisture contamination, and fine particle abrasion, effectively protecting downstream separators, meters, and precision fuel distribution equipment.

Professional Coalescing Working Principle

The I-614C5TB adopts multi-layer gradient hydrophilic fiberglass media optimized for aviation fuel demulsification. Fuel fluid flows from the inner core to the outer media layer (inside-to-out flow path). The graded fiber structure first traps fine suspended solids, rust debris, and granular contaminants to prevent media surface blinding.

As the fluid penetrates the high-density hydrophilic fiberglass layer, invisible emulsified water droplets are captured and adsorbed by microfibers. Under continuous fluid shear force, scattered micro-droplets collide, merge, and aggregate into large-diameter water beads. Due to gravity difference, the enlarged water droplets separate rapidly from hydrocarbon fuel and settle at the bottom of the filter vessel, achieving thorough dry fuel purification while maintaining stable flow pressure for long-term operation.

Velcon I-614C5TB Exclusive Structural Features

1. Standard 14-Inch Threaded Base Configuration

Featuring an accurate threaded base end cap, the I-614C5TB enables fast, stable installation and tight locking inside Velcon filter housings. The threaded structure avoids loose displacement under fluid impact, ensuring sealing stability during long-cycle continuous fuel flow. It perfectly matches original assembly standards with zero installation modification required.

2. Aviation-Grade Hydrophilic Fiberglass Media

Adopting premium multi-density borosilicate fiberglass material, the filter media delivers superior hydrophilic performance and high particle retention accuracy. It efficiently breaks fine fuel emulsions and captures submicron water mist, maintaining consistent demulsification efficiency without fiber shedding, media deformation, or performance degradation.

3. High-Strength Epoxy Integral Bonding

End caps and filter media are bonded with industrial high-strength epoxy resin, forming an integrated anti-leakage structure. This full bonding process eliminates bypass leakage risks and enhances structural rigidity, resisting pressure fluctuation and fluid scouring in 24/7 continuous fuel processing environments.

4. Standard Industrial Dimension Design

OD 6.0 inch, ID 3.5 inch, 14-inch overall length strictly follows Velcon original industry specifications, ensuring full dimensional interchangeability with genuine I-614C5TB cartridges for global standard filter separator vessels.
