Introduction

LEFILTER, a leading Chinese manufacturer with over 15 years of expertise in industrial fluid purification, introduces the Replacement Velcon Coalescer Filter Model I-638C5. Engineered as a direct replacement for Velcon’s original I-638C5, this product offers identical performance, durability, and compatibility while delivering significant cost savings. Backed by ISO 9001, ISO 14001, and ISO 45001 certifications, LEFILTER ensures seamless integration into Velcon filter systems across industries such as petrochemicals, aviation, and natural gas.

Product Overview

The Replacement Velcon Coalescer Filter Model I-638C5 is designed for efficient separation of water and solids from hydrocarbon-based fluids. Using advanced hydrophilic composite materials, it coalesces emulsified water droplets into larger volumes, which are then removed via gravity separation. This process ensures purified liquids for critical operations, protecting downstream equipment from corrosion and damage.

Applications

Petrochemical Industry

• Refineries: Removes water and particulates from crude oil, diesel, and gasoline.

• Chemical Processing: Ensures clean solvents and process fluids in pharmaceutical and specialty chemical production.

• Pipeline Systems: Prevents water-induced corrosion and blockages in hydrocarbon transportation.

Other Industries

• Aviation: Safeguards jet fuel systems from water contamination.

• Natural Gas: Dehydrates gas streams to meet pipeline quality standards.

• Marine: Protects engines and fuel systems in maritime environments.

Working Principle

The Replacement Velcon Coalescer Filter Model I-638C5 operates through a three-stage process:

1. Filtration: Mechanical impurities are trapped by the filter’s multi-layer media.

2. Coalescence: Hydrophilic materials merge small water droplets into larger ones.

3. Separation: Gravity causes coalesced water to settle, while purified oil passes through.

Features

• High Efficiency: Removes ≥99.9% of water and solids from liquids.

• Durable Construction: Composite materials resist corrosion and mechanical stress.

• Direct Replacement: Interchangeable with Velcon’s I-638C5 without system modifications.

• ISO Compliance: Manufactured to ISO 2941 (burst resistance), ISO 2942 (integrity testing), and ISO 16889 (multi-pass performance).
