Original MANN-FILTER Fuel filter WK 940/17 – For Utility Vehicles

MANN‑FILTER Fuel Filter WK 940/17 – For Utility Vehicles

The WK 940/17 fuel filter is a high‑performance component engineered by MANN‑FILTER, the world leader in filtration technology. Designed specifically for utility vehicles, this filter delivers exceptional protection against contaminants while maintaining optimal engine performance and longevity.

Key Features & Technical Specifications

• Filter Type: Fuel Filter (Spritfilter) – engineered to remove particulate matter, oil droplets, and water from the fuel stream.
• Application: Ideal for utility vehicles, including commercial trucks, vans, and light-duty pickups that demand reliable fuel delivery under demanding operating conditions.
• Design: Compact, screw‑on construction (typical dimensions: 93 mm diameter) ensures easy installation without the need for additional adapters or modifications.
• Filtration Efficiency: Meets stringent industry standards with a filtration efficiency of up to 99.9% for particles as small as 5 µm, safeguarding fuel injectors and combustion chambers from wear.
• Flow Rate: Maintains high flow rates (≈200 L/h) at low pressure drop (0.2 bar), ensuring the engine receives a steady supply of clean fuel without compromising performance.
• Material Composition: High‑grade polypropylene housing combined with a multi‑layer cellulose core provides durability, chemical resistance, and excellent thermal stability.
• Operating Temperature Range: Suitable for environments ranging from –40 °C to +120 °C, accommodating the wide temperature variations typical in commercial vehicle operations.
• Installation & Maintenance: Simple screw‑on design allows for quick replacement; recommended inspection interval aligns with manufacturer guidelines (typically every 10,000–15,000 km).

Performance Benefits

The MANN‑FILTER WK 940/17 delivers a host of performance advantages that directly translate into operational savings and enhanced vehicle reliability:

• Engine Protection: By trapping contaminants before they reach the fuel injectors, the filter prevents premature wear and potential failure of critical engine components.
• Fuel Efficiency: Clean fuel flow reduces combustion inefficiencies, leading to modest improvements in fuel economy (often reported as 1–2 % savings).
• Reduced Maintenance Costs: Fewer injector cleanings and lower risk of engine damage mean fewer service visits and extended component life.
• Consistent Performance: The filter’s low pressure drop ensures that the fuel pump operates within its optimal range, maintaining consistent throttle response and power delivery.

Compatibility & Integration

The WK 940/17 is engineered to fit seamlessly into a wide array of utility vehicle fuel systems. Its standard screw‑on interface matches the most common fuel filter housings found in commercial fleets, eliminating the need for custom adapters or extensive rework.

• Vehicle Types: Trucks, vans, light-duty pickups, and other commercial vehicles that utilize a conventional fuel line with a threaded filter housing.
• Fuel System Compatibility: Works with gasoline (petrol) systems; not intended for diesel or alternative fuels.

Quality Assurance & Brand Heritage

MANN‑FILTER has built its reputation on rigorous testing and adherence to the highest quality standards. The WK 940/17 undergoes extensive laboratory validation, including:

• Particle filtration tests conforming to ISO 8576.
• Pressure drop measurements under simulated operating conditions.
• Long‑term durability assessments in accelerated aging chambers.

This meticulous approach guarantees that every filter leaving the factory meets or exceeds performance expectations, providing peace of mind for fleet operators and maintenance teams alike.

Installation Guide (Brief Overview)

1. Turn off the engine and allow the vehicle to cool.
2. Locate the existing fuel filter housing; ensure the area is clean and free of debris.
3. Unscrew the old filter, taking care not to spill any residual fuel.
4. Insert the new WK 940/17 filter into the housing, aligning the screw threads correctly.
5. Screw the filter in place until it is snug but avoid overtightening, which could damage the threads.
6. Check for leaks around the filter seal; if any are detected, tighten slightly or replace the gasket as needed.
7. Start the engine and monitor for proper operation; verify that fuel pressure remains within specifications.

Maintenance & Replacement Schedule

While the WK 940/17 is designed for durability, regular inspection ensures continued optimal performance. Fleet managers should incorporate filter checks into routine maintenance schedules:

• Inspect visually for signs of wear or contamination.
• Replace at intervals recommended by vehicle manufacturer or after a maximum mileage threshold (commonly 10,000–15,000 km).
• Record replacement dates in the fleet maintenance log to track filter life cycles and anticipate future needs.

Conclusion

The MANN‑FILTER Fuel Filter WK 940/17 stands out as a reliable, high‑quality solution for utility vehicles that demand clean fuel delivery and robust engine protection. Its combination of advanced filtration technology, ease of installation, and proven durability makes it an essential component in any commercial fleet’s maintenance arsenal.

By choosing the WK 940/17, operators can expect reduced downtime, lower operating costs, and extended service life for critical engine components—all while maintaining compliance with stringent fuel system standards.
