Original MANN-FILTER Fuel filter WK 962/4 – For Utility Vehicles

Product Overview

The MANN‑FILTER Fuel Filter WK 962/4 is a high‑performance fuel filtration solution specifically engineered for utility vehicles, including commercial trucks, buses, and heavy‑duty machinery. Designed with precision engineering and rigorous testing standards, this filter guarantees optimal engine protection by removing contaminants that can compromise fuel quality and engine longevity.

Key Features & Technical Highlights

• Advanced Filtration Technology: Utilizes a multi‑layered media system that captures particles as small as 5 µm, ensuring clean fuel delivery to the combustion chamber.
• Robust Construction: Made from durable polypropylene housing with reinforced seals, providing resistance against high pressure and temperature variations typical in heavy‑duty operations.
• High Flow Capacity: Engineered to maintain low pressure drop (≤ 5 kPa) across a wide range of flow rates, preventing performance loss while delivering superior filtration.
• Long Service Life: Designed for extended service intervals (up to 12,000 km or 12 months) under normal operating conditions, reducing maintenance frequency and downtime.
• Universal Fitment: Compatible with a broad spectrum of diesel engines used in commercial fleets, including DAF, MAN, Steyr, GM, and other major manufacturers.
• Easy Installation: Screw‑on design (threaded connection) allows for quick replacement without specialized tools or extensive disassembly.

Design & Engineering Excellence

The WK 962/4 incorporates a proprietary filtration media blend that balances high particle capture efficiency with minimal resistance to fuel flow. The filter housing features an integrated pressure gauge port, enabling real‑time monitoring of pressure differential and early detection of clogging events.

Material Selection

Polypropylene is chosen for its excellent chemical resistance against diesel additives and fuels containing high levels of water or contaminants. The internal media layers are bonded using a low‑temperature process that preserves the structural integrity of the fibers, ensuring consistent performance over the filter’s lifespan.

Thermal & Mechanical Resilience

The filter can withstand operating temperatures up to 120 °C and pressure ranges typical for fuel systems in heavy vehicles. Its reinforced housing resists deformation under load, maintaining seal integrity even during vibration or shock events common on rough terrain.

Installation & Maintenance Guidelines

Proper installation is critical to achieving the filter’s full performance potential. Follow these steps:

1. Preparation: Ensure the vehicle’s engine is cool and the fuel system is depressurized according to manufacturer safety procedures.
2. Removal of Existing Filter: Unscrew the old filter using a suitable wrench, allowing any residual fuel to drain into a safe container.
3. Installation: Align the new WK 962/4 with the threaded connection and tighten by hand until snug. Use a torque wrench set to the manufacturer’s specified value (typically 15 Nm) for final tightening.
4. Leak Check: Inspect all connections for leaks after starting the engine and allowing it to reach operating temperature.
5. Documentation: Record installation date, mileage, and any observations in the vehicle’s maintenance log.

Routine Inspection

At each scheduled service interval, check the pressure gauge port for a rise in differential pressure. A sudden increase indicates media saturation and necessitates filter replacement to prevent fuel starvation or engine damage.

Benefits for Utility Vehicle Operators

• Enhanced Engine Protection: By eliminating fine particulates, the filter reduces wear on injectors, pumps, and valves, extending component life.
• Improved Fuel Efficiency: Clean fuel flow ensures optimal combustion, potentially reducing fuel consumption by up to 2 % in some applications.
• Reduced Maintenance Costs: Longer service intervals and fewer filter replacements translate into lower operating expenses over the vehicle’s lifecycle.
• Reliability on Challenging Routes: The filter’s robust design maintains performance even when traversing dusty or gravelly roads, common in construction and logistics operations.

Compatibility & Application Spectrum

The WK 962/4 is engineered to fit a wide array of diesel engines used across the commercial vehicle sector. Common applications include:

• Heavy‑Duty Trucks: DAF, MAN, Steyr, and GM models.
• Buses & Coaches: Commercial passenger vehicles requiring reliable fuel delivery.
• Construction Machinery: Excavators, loaders, and other equipment operating in dusty environments.
• Agricultural Vehicles: Tractors and harvesters that benefit from extended filter life under variable load conditions.

Quality Assurance & Compliance

The MANN‑FILTER WK 962/4 meets or exceeds all relevant industry standards, including ISO 9001 for quality management and DIN EN 590 for diesel fuel specifications. Each batch undergoes rigorous laboratory testing to verify filtration efficiency, pressure drop, and mechanical integrity before shipment.

Environmental Considerations

The filter’s design minimizes waste by allowing for extended use, thereby reducing the frequency of disposal and associated environmental impact. Additionally, its materials are recyclable under standard industrial recycling protocols.

Conclusion

For operators seeking a dependable, high‑performance fuel filtration solution in utility vehicles, the MANN‑FILTER Fuel Filter WK 962/4 delivers unmatched protection, efficiency, and longevity. Its advanced technology, robust construction, and ease of maintenance make it an essential component for any fleet that demands reliability on demanding routes.
