Product Introduction
The Velcon I-644C5 is a high-performance standard coalescing filter element designed for medium-flow fuel and hydrocarbon liquid purification. It serves as the core primary filtration component in Velcon filter separators, tasked with coalescing tiny suspended water droplets and intercepting fine solid particles in fuel media. Our factory provides a fully compatible aftermarket replacement for the I-644C5 model. The replacement strictly replicates the original installation size, end interface, sealing structure and overall assembly standards, enabling direct drop-in replacement without equipment modification. Compared with expensive original Velcon elements, our alternative features low cost and stable performance, solving the problem of high consumption costs for industrial fuel filtration.
Main Application Scenarios
The I-644C5 coalescing filter is widely used in medium-flow fuel purification scenarios, focusing on fuel dehydration and impurity removal to ensure medium cleanliness and protect downstream equipment:

Advantages of Our I-644C5 Replacement Coalescing Filter
Our aftermarket I-644C5 coalescing filter is developed and produced to fully match the original equipment standard, with outstanding cost performance and practicality for industrial mass consumption scenarios.
1. Precise Overall Adaptation, Universal Installation
The overall size, end cap structure, sealing size and assembly gap are strictly calibrated according to the original Velcon standard. The replacement element can be directly installed in the original filter separator without any modification, gasket replacement or tool adjustment, featuring strong universality and convenient replacement operation.
2. Stable Filtration Performance, Practical Industrial Grade Quality
Adopting gradient multi-layer glass fiber coalescing medium, the product has uniform pore size and strong dirt-holding capacity. It can stably coalesce tiny emulsified water and intercept fine impurities in fuel, maintaining consistent filtration effect with the original element, fully meeting daily industrial fuel purification standards.
3. Ultra-Low Procurement Cost, Reduce Operating Expenses
Directly supplied by the factory without brand premium and intermediate circulation links. On the premise of ensuring stable use effect, the price is far lower than the original Velcon filter element. Long-term bulk procurement can greatly reduce the daily consumable cost of fuel filtration equipment for enterprises.
4. Reliable Quality Control and Flexible Supply
Each batch of products is tested for water coalescence effect and pressure difference stability before delivery. Standard models are in sufficient stock for fast delivery. We support small-batch trial orders and customized processing of special sealing materials and structures, with complete after-sales service and export supporting documents.
