Velcon I-622C5 Coalescing Filter

The Velcon I-622C5 is a 22-inch aviation-grade plain-end coalescing filter element designed for standard Velcon fuel filter separator systems. Complying with EI 1581 6th Edition aviation filtration standards, this extended-length coalescer features enlarged filtration area and superior dirt holding capacity compared with 14-inch short models. It specializes in removing fine solid contaminants, free water and stubborn emulsified water from jet fuel and diesel, delivering consistent high-precision fuel purification for medium-flow airport fuel depots, refineries and bulk fuel terminal facilities.

Product Introduction

Overview

Velcon I-622C5 belongs to the extended-size lineup of Velcon classic I-series coalescing filters. Different from the threaded-base I-622C5TB version, this model adopts plain smooth end caps for traditional clamp-type housing installation.

With a 22-inch full-length gradient hydrophilic fiberglass structure, the I-622C5 provides larger flux volume and longer service life than standard short coalescers. It effectively solves common fuel problems such as turbidity, emulsification and fine particle contamination, ensuring stable fuel cleanliness for long-term continuous fuel transfer and processing systems.

Working Principle

The I-622C5 adopts inside-to-out progressive coalescing filtration:The outer gradient fiber layer disperses high-speed fuel flow and intercepts large sediment, rust and mechanical impurities to prevent premature clogging.The inner high-hydrophilic fiberglass layer captures micron-level emulsified water droplets suspended in fuel.Tiny water droplets collide, adsorb and polymerize under continuous fluid shear force, forming large water beads.Water separates from fuel by gravity settlement, achieving complete water-oil separation and dry fuel output.

Product Features

  • 22-inch extended body, larger filtration area and higher flow throughput

FAQ

Q: What is the difference between I-622C5 and I-622C5TB?A: I-622C5 is plain end for clamp installation; I-622C5TB is threaded base for screw-lock housings. Both have the same 22-inch length and identical filtration performance.
Q: Why choose 22-inch coalescer over 14-inch model?A: 22-inch extended media offers larger filtration area, higher flow capacity and longer replacement cycle, ideal for medium-flow continuous fuel purification systems.
Q: Is this element aviation standard certified?

A: Yes, fully manufactured and tested according to EI 1581 6th Edition aviation fuel filtration specifications.
