Velcon I-622C5TB Coalescing Filter
The Velcon I-622C5TB is a 22-inch threaded-base aviation-grade coalescing filter element, serving as a core first-stage filtration component for Velcon fuel filter separator systems. Complying strictly with EI 1581 6th Edition global aviation standards, this threaded coalescer features extended media length for larger flow rate and higher dirt holding capacity compared with standard 14-inch models. It reliably removes fine solid contaminants and micron-sized emulsified water from jet fuel, diesel and industrial hydrocarbon fluids, delivering stable, long-lasting purification performance for medium and large-scale aviation depots, refineries and commercial fuel terminal systems.
Product Introduction
Overview
Velcon I-622C5TB is an extended-size threaded-base coalescing filter element of the classic Velcon I-series. Different from short plain-end models, the C5TB threaded base structure enables fast screw locking installation, more stable sealing under high-flow fluctuating pressure, and avoids element displacement during long-cycle operation.
With 22-inch full-length gradient hydrophilic fiberglass media, the I-622C5TB provides larger filtration area and higher contaminant retention capacity, effectively solving fuel emulsification, turbidity and fine particle abrasion problems. It is a preferred upgrade solution for medium-flow fuel purification systems pursuing longer service intervals and lower maintenance frequency.
Working Principle
Adopting inside-to-out progressive coalescing filtration:
Outer open fiber layer disperses high-speed fluid flow and intercepts large sediment, rust and mechanical impurities to prevent early media blocking.
Inner high-hydrophilic fine fiber layer captures invisible emulsified water droplets suspended in fuel.
Micro-droplets continuously collide, aggregate and grow into large water beads under fluid shear force.
Gravity separation realizes thorough water-oil separation, outputting dry and high-cleanliness fuel.

FAQ
Q: What are the advantages of I-622C5TB over 14-inch models?
A: The 22-inch extended design provides larger filtration area, higher flow tolerance and bigger dirt holding capacity, suitable for medium and large flow fuel systems with longer running cycles.
Q: What does TB stand for?
A: TB means Threaded Base, designed for screw-type quick-install Velcon filter vessels, more stable than clamp mounting under pressure fluctuation.
Q: Is full series Velcon I-series available?
A: Yes, we supply all C5 plain end and C5TB threaded base models from 14-inch to 56-inch.
