High-Efficiency Replacement Faudi Separator Filter Element – 60.645 Series

Overview

The Faudi 60.645 Series separator filter elements are precision-engineered second-stage components designed for filter/water separator (FWS) systems used extensively in fuel distribution networks and aviation ground fueling applications . As a direct replacement for original Faudi-branded separators, these 6-inch (152mm) outer diameter elements feature advanced hydrophobic Teflon-coated screen technology that effectively repels water while allowing clean fuel to pass through .

Qualified to EI 1581 6th Edition Category C standards, the 60.645 series ensures reliable water removal from Jet A-1, diesel, and gasoline, protecting critical equipment from water-induced corrosion and contamination . These replacement elements are constructed with epoxy-coated steel inner tubes, glass fiber reinforced polyamide end caps stamped with date of manufacture and ID number per EI specifications, and NBR (Buna-N) end seals for leak-proof performance .

Working Principle

The 60.645 separator elements function as the second stage in filter/water separator systems :

1. Solid Filtration: Fuel flows from outside to inside, trapping solid contaminants such as rust and particulate matter

2. Hydrophobic Separation: The Teflon-coated screen effectively repels water while allowing fuel to permeate. Water droplets coalesce on the surface until they become large enough to fall into the collection sump 

3. Gravity Settling: Separated water collects at the bottom of the housing for periodic drainage

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

Key Applications

The 60.645 series separator elements are widely deployed in:

• Aviation Fuel Systems: Jet fuel purification meeting ASTM D1655 standards for commercial and military aircraft

• Oil & Gas Operations: Dehydration of natural gas pipelines and refinery processes

• Marine Fuel Conditioning: Fuel and lubrication systems for ships and offshore platforms

• Ground Refueling Equipment: Mobile and stationary refueling units, tank farms, and marine loading terminals 

---

Quality Assurance

Each replacement element undergoes rigorous quality control:

• 100% pre-delivery testing for burst strength (ISO 2941), structural integrity (ISO 2942), and separation efficiency 

• Manufactured under ISO 9001, ISO 14001, and ISO 45001 certified processes

• Full traceability with material certifications and performance test reports

Frequently Asked Questions (FAQ)

Q1: Are these replacement elements compatible with existing Faudi 60.645 filter housings?

A: Yes, these replacement elements are engineered as drop-in equivalents for Faudi 60.645 series filter vessels. They feature identical dimensions—152mm (6-inch) outside diameter, 89mm (3-inch) inside diameter, and matched length specifications—along with the same end-cap configurations and NBR sealing geometry. No system modifications are required for installation .

Q2: What is the difference between the "D" and "P" suffix designations in the model numbers?

A: The "D" suffix typically indicates elements with Teflon®-coated stainless steel screen mesh, which can be cleaned and reused in some applications. The "P" suffix generally denotes synthetic plastic mesh elements designed for single-use disposable applications. Both configurations meet EI 1581 6th Edition standards but offer different maintenance characteristics .

Q3: What industry standards do these separator elements comply with?

A: The 60.645 series replacement elements are qualified to EI 1581 6th Edition Category C standards for aviation fuel filtration. They also comply with ISO 2941 (burst resistance testing), ISO 2942 (structural integrity testing), and are manufactured under ISO 9001, ISO 14001, and ISO 45001 certified quality management systems .

Q4: How often should the separator elements be replaced?

A: Replacement intervals depend on operating conditions, fuel quality, and system requirements. Typically, separator elements should be replaced when pressure differential reaches the manufacturer's recommended limit or during scheduled maintenance cycles. Regular visual inspection for media damage or contamination is also recommended. Many aviation and industrial operators follow annual replacement schedules or replace elements after a specified number of operating hours .
