Working Principle

The 60.644 separator elements function as the second stage in filter/water separator (FWS) systems :

1. Filtration: Incoming fuel passes through the element from outside to inside, trapping solid particles such as rust and debris

2. Hydrophobic Separation: The Teflon-coated screen effectively repels water while allowing oil to flow through. Water droplets collect on the surface until they grow large enough to fall into the collection sump 

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

This two-stage mechanism achieves up to 99.9% water removal efficiency, ensuring fuel purity for critical applications .

Key Applications

The 60.644 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, compressor suction protection, and refinery processes 

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

• Petrochemical Processing: Separation of hydrocarbons and solvents in corrosive environments 

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

---

Quality Assurance

Each replacement element undergoes rigorous quality control processes:

• 100% pre-delivery testing for burst strength, structural integrity, and separation efficiency 

• Compliance with ISO 9001, ISO 14001, and ISO 45001 certified manufacturing processes 

• Full traceability with material certifications and performance test reports

Frequently Asked Questions (FAQ)

Q1: Are these replacement elements compatible with existing Faudi 60.644 filter housings?

A: Yes, these replacement elements are engineered as drop-in equivalents for Faudi 60.644 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 60.644 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 .
