Product Introduction

Product Overview

The Velcon I-644C5TB is a standard threaded-base coalescing filter element compliant with EI 1581 global filtration standards, specially designed for medium-flow fuel distribution and petrochemical fluid processing systems. Featuring a 44-inch optimized body structure and large dirt-holding capacity, this model focuses on continuous stable filtration for circulating fuel delivery systems, effectively solving water contamination and fine particle pollution in low-viscosity hydrocarbon media. Our factory offers fully compatible aftermarket replacement for the original Velcon I-644C5TB filter. Strictly manufactured to replicate the original threaded base interface, overall dimensional tolerance and sealing matching standards, our replacement element supports direct drop-in installation with no need for equipment modification, pipeline adjustment or accessory replacement. Removing imported brand premiums and multi-level agency costs, our low-cost alternative maintains OEM-level filtration stability, perfectly solving the pain points of high operating costs and long delivery cycles of original filters for fuel distribution and petrochemical enterprises.


Core Application Scenarios

Different from large-flow oil depot and single-scenario filtration elements, the I-644C5TB adapts to circulating and continuous fuel delivery working conditions, focusing on aviation distribution, petrochemical processing and industrial fluid circulation fields:

1. Aviation Fuel Distribution System
Suitable for airport underground fuel pipeline circulation systems and aviation fuel centralized distribution stations. It continuously removes emulsified water and tiny impurities generated during fuel circulating transmission, stabilizes fuel cleanliness in real time, and ensures safe and standard fuel supply for aircraft refueling operations.
2. Petrochemical Light Hydrocarbon Processing
Widely used for purification of light hydrocarbon media such as toluene, xylene and cyclohexane in chemical plants. It eliminates mixed free water and process fine dust in organic solvents, improves solvent purity, and guarantees stable progress of chemical synthesis and extraction processes.
3. Industrial Circulating Lubricant Filtration
Applied to online purification of turbine oil and low-viscosity hydraulic oil in industrial production lines. It separates trace moisture in circulating lubricants, prevents oil emulsification deterioration, avoids equipment lubrication failure and component wear, and extends lubricant replacement cycle.
4. Commercial Fuel Transit & Supply
Matched with medium-flow fuel transfer equipment and regional fuel distribution stations. It filters impurities and condensed water mixed during fuel transshipment and storage, ensures qualified fuel supply for gas stations and industrial equipment, and reduces post-use maintenance costs of terminal equipment.
