Original MANN-FILTER Oil Filter W 940/55 – For utility vehicles

Overview of the MANN‑FILTER Oil Filter W 940/55

The MANN‑FILTER Oil Filter W 940/55 is a premium filtration solution engineered for utility vehicles that demand reliable protection and consistent performance. Designed with advanced filter media and robust construction, this oil filter delivers superior contaminant removal while maintaining optimal flow rates across a wide range of operating conditions.

Key Design Features

• High‑Efficiency Media: Utilizes a multi‑layered filtration matrix that captures particles as small as 0.5 µm, ensuring engine oil remains free from sludge and wear debris.
• Durable Housing: Constructed from high‑strength alloy steel with corrosion‑resistant coatings, the housing withstands harsh environments and extended service intervals.
• Non‑Return Valve: Integrated valve prevents oil backflow, protecting the engine’s lubrication system during sudden pressure changes or shutdowns.
• Threaded Mounting (3/4‑16 UNF): Standardized threading guarantees a secure fit on most utility vehicle engines without the need for adapters.
• Optimized Flow Dynamics: Engineered to minimize pressure drop, preserving engine efficiency and reducing fuel consumption.

Compatibility Spectrum

The W 940/55 filter is engineered to fit a broad range of utility vehicle engines. Its universal design accommodates:

• Commercial trucks and vans with inline or V‑type configurations.
• Heavy‑duty diesel engines used in construction equipment.
• Lightweight gasoline engines found in delivery vehicles.

Performance Benefits

By maintaining pristine oil quality, the MANN‑FILTER Oil Filter W 940/55 offers:

• Extended Engine Life: Reduces wear on bearings and pistons by eliminating abrasive particles.
• Improved Fuel Economy: Lower pressure drop translates to less energy spent pumping oil.
• Consistent Lubrication: Maintains optimal viscosity, especially under high‑temperature or high‑load conditions.
• Reduced Maintenance Frequency: High filtration efficiency allows for longer intervals between filter changes without compromising protection.

Installation & Maintenance Guidelines

1. Preparation: Ensure the engine is cool and the oil drain plug is removed to allow any residual oil to flow out before installation.
2. Removal of Old Filter: Use a filter wrench or hand tool to unscrew the existing filter. Dispose of it responsibly.
3. Installation Steps:*
• Apply a thin layer of fresh engine oil to the gasket surface.
• Thread the new W 940/55 filter onto the housing clockwise until snug, then give an additional quarter turn for a secure seal.
• Reinstall the drain plug and refill the engine with recommended oil grade.
4. Post‑Installation Check: Inspect for leaks around the filter threads and verify that the non‑return valve functions correctly by observing the flow during a brief engine start.

Material Composition & Environmental Considerations

The filter media is composed of high‑grade cellulose fibers bonded with synthetic polymers, providing excellent filtration without compromising oil quality. The housing’s alloy steel construction is recyclable, aligning with sustainability goals for fleet operators seeking eco‑friendly components.

Quality Assurance & Compliance

Manufactured under stringent quality control protocols, the MANN‑FILTER Oil Filter W 940/55 complies with international automotive standards. Its design adheres to OEM specifications for major utility vehicle manufacturers, ensuring seamless integration into existing maintenance workflows.

Conclusion

The MANN‑FILTER Oil Filter W 940/55 stands out as a reliable, high‑performance component tailored for the demanding environments of utility vehicles. Its blend of advanced filtration media, robust construction, and user‑friendly installation makes it an essential upgrade for fleet operators aiming to protect engine integrity while optimizing operational efficiency.
