Replacement Faudi 60.644-179/D Separator Filter Element – Product Guide

Introduction

In filter/water separator systems, the separator element serves as the critical final barrier against water contamination. After the coalescer stage merges microscopic water droplets into larger ones, the separator element ensures that any remaining water is blocked from passing downstream to engines, turbines, or hydraulic systems. The Faudi 60.644-179/D separator element, with its 179mm nominal length, is one of the most compact configurations in the 60.644 series, making it ideal for space-constrained filter housings and smaller fuel handling systems.

This replacement element is constructed with an epoxy-coated steel inner tube covered with a separator screen available in either Teflon®-coated stainless steel mesh or synthetic plastic mesh configurations. The end caps are made from glass fibre reinforced polyamide and are stamped according to EI standards with date of manufacture and ID number, while NBR (Buna-N) end seals ensure leak-proof performance. Qualified to EI 1581 6th Edition Category C standards, it delivers reliable water separation for demanding fuel applications.

Model Specification – 60.644-179/D

How the Separator Element Works

The 60.644-179/D separator element operates as the second stage in filter/water separator systems:

1. Filtration: Incoming fuel flows from outside to inside, trapping solid particles including rust, debris, and particulate matter.

2. Water Repulsion: The hydrophobic separator screen repels water while allowing fuel to permeate. Water droplets collect on the surface until they become large enough to fall into the collection sump.

3. Gravity Settling: Separated water accumulates at the bottom of the housing for periodic drainage, ensuring only clean, dry fuel exits the system.

This three-stage mechanism ensures that water particles not captured during the coalescer stage are effectively blocked, delivering fuel purity that meets the most stringent industry requirements.

Applications

The 60.644-179/D separator element is deployed across multiple critical industries:

• Mobile and stationary refuelling equipment

• Tank farms

• Ships and loading terminals

• Refineries

• Aviation fuel systems

Its compact 179mm length makes it particularly suitable for smaller filter housings and space-constrained installations where full-length elements cannot be accommodated.

Performance Benefits

• High Water Removal: Reliable separation efficiency for critical fuel applications

• Reusable Option: Teflon®-coated elements can be cleaned and reused

• Durable Construction: Epoxy-coated steel inner tube ensures structural integrity

• EI Compliance: Stamped with date of manufacture and ID number per EI specifications

• Compact Design: 179mm length ideal for space-constrained filter housings

Frequently Asked Questions (FAQ)

Q1: What is the difference between the "D" and "P" suffix versions in the 60.644-179 series?

A: The "D" suffix indicates elements with Teflon®-coated stainless steel screen mesh, which can be cleaned, inspected, and reused during coalescer element changeouts. Small areas of damage can be temporarily repaired. The "P" suffix denotes synthetic plastic mesh elements designed for single-use disposable applications, which should be replaced during coalescer element changeouts.

Q2: What are the recommended storage conditions for this separator element?

A: The manufacturer recommends storage at 20°C with maximum 50% humidity in original packaging. The maximum storage time is 60 months from the date of shipment out of stock.

Q3: Is this replacement element compatible with existing Faudi 60.644-179/D filter housings?

A: Yes, this replacement element is engineered as a drop-in equivalent for Faudi 60.644-179/D series filter vessels. It features identical dimensions—152mm (6-inch) outside diameter, 89mm (3-inch) inside diameter, and 179mm nominal length—along with the same end-cap configuration and NBR sealing geometry. No system modifications are required for installation.

Q4: What quality certifications does this separator element meet?

A: The 60.644-179/D replacement element is qualified to EI 1581 6th Edition, Category C standards for aviation fuel filtration. It is manufactured under ISO 9001, ISO 14001, and ISO 45001 certified quality management systems. Each element undergoes rigorous quality control and 100% pre-delivery testing for burst strength, structural integrity, and separation efficiency.
