Replacement Faudi 60.4C4 Series Separator Filter Element – Product Guide

Introduction

In aviation fuel systems and hydrocarbon processing operations, water contamination poses a serious threat to equipment reliability and operational safety. The Faudi 60.4C4 series separator elements serve as the critical final barrier against water in filter/water separator systems. After the coalescer stage merges microscopic water droplets into larger ones, these separator elements ensure that any remaining water is blocked from passing downstream to engines, turbines, or hydraulic systems.

The 60.4C4 series replacement elements are constructed with a robust multi-layered design featuring hydrophobic PTFE-coated stainless steel mesh as the core material, reinforced center tubes and pleated fiberglass layers for enhanced mechanical strength, and high-temperature resistant silicone gaskets for leak-proof performance. These elements are adaptable to both horizontal and vertical filter housings, making them versatile solutions for diverse fuel handling applications.

Complete Model Range – 60.4C4 Series

Replacement models available for the Faudi 60.4C4 series include the following part numbers:

All models feature 152mm (6-inch) outside diameter and 89mm (3-inch) inside diameter, with variations in nominal length.

Technical Specifications

How the Separator Element Works

The 60.4C4 separator elements operate through a three-stage separation mechanism:

1. Filtration: Incoming fuel passes through multi-layered media that traps solid particles including rust, debris, and particulate matter.

2. Coalescence: Microscopic water droplets merge into larger ones within the hydrophilic layers, growing in size until they can be effectively separated.

3. Separation: The hydrophobic PTFE-coated mesh repels water while allowing purified fuel to flow through. Gravity causes the separated water to settle into a collection chamber for periodic drainage.

This design ensures that water droplets not captured during the coalescer stage are effectively blocked, delivering clean, dry fuel that meets the most stringent industry requirements.

Frequently Asked Questions (FAQ)

Q1: What is the difference between the 60.4C4 and 60.644 series separator elements?

A: Both series share similar 6-inch (152mm) outside diameter and 3-inch (89mm) inside diameter dimensions, but they differ in their specific length configurations and applications. The 60.4C4 series is particularly suited for aviation fuel purification and hydraulic fluid conditioning, while the 60.644 series is more commonly deployed in general fuel distribution networks. Both series offer equivalent performance when matched to their specified filter housings.

Q2: What is the filtration efficiency of the 60.4C4 series separator elements?

A: These separator elements achieve ≥99.9% filtration efficiency at 10 μm, ensuring effective removal of water droplets and solid contaminants from aviation fuels and hydrocarbon fluids. The hydrophobic PTFE-coated stainless steel mesh core provides reliable water repulsion while maintaining optimal flow rates.

Q3: Are these replacement elements compatible with existing Faudi 60.4C4 filter housings?

A: Yes, these replacement elements are engineered as drop-in equivalents for Faudi 60.4C4 series filter vessels. They feature identical dimensions—152mm (6-inch) outside diameter, 89mm (3-inch) inside diameter, and matched length specifications—along with compatible end-cap configurations and sealing geometry. The elements are adaptable to both horizontal and vertical filter housings without requiring system modifications.

Q4: What quality certifications do these separator elements meet?

A: The 60.4C4 series replacement elements are manufactured under ISO-certified quality management systems and comply with ISO 2941 (burst resistance testing), ISO 2942 (structural integrity testing), ISO 2943, and CE standards. Each element undergoes rigorous quality control and pre-delivery testing to ensure reliable water separation performance and structural integrity.
