The Mann Filter W9401 Lube Filter is a high‑performance oil filter designed for a wide range of automotive and industrial applications. It delivers superior protection, ensuring that engine or hydraulic systems operate smoothly and reliably.

Key Features

• Advanced Filtration Technology: Utilises multi‑layer media to capture particles as small as 0.5 µm, protecting internal components from wear.
• Anti‑Return Valve: Prevents backflow of contaminated oil, maintaining filter integrity and extending service life.
• Robust Construction: Made with high‑grade polypropylene housing that resists corrosion and temperature extremes.
• Wide Compatibility: Fits a broad range of vehicles and machinery, including Audi, Ford, Fiat, Lancia, Ferrari, Volvo, Toyota, and many others.
• Easy Installation: Screw‑on design with 3/4‑inch diameter and 16 UNF threads for quick, tool‑free replacement.

Applications

The W9401 is engineered to meet the demands of both passenger cars and heavy machinery. Typical uses include:

• Engine oil filtration in gasoline and diesel engines.
• Hydraulic fluid filtering for transmission systems.
• Industrial equipment such as forklifts, generators, and construction machines.

Performance Benefits

By maintaining optimal oil cleanliness, the W9401 contributes to:

• Reduced engine wear and extended service intervals.
• Improved fuel efficiency through lower friction.
• Enhanced reliability in critical applications like heavy-duty trucks and industrial hydraulics.

Installation Guide

1. Turn off the engine or shut down hydraulic system.
2. Drain existing oil if required.
3. Unscrew the old filter carefully, allowing any residual oil to drain.
4. Clean the mounting surface with a lint‑free cloth.
5. Screw on the new W9401 filter clockwise until snug; avoid overtightening.
6. Refill with fresh oil or hydraulic fluid as specified by the manufacturer.

Maintenance Tips

• Check filter condition during routine maintenance checks.
• Replace after every recommended service interval, typically every 10,000–15,000 km for passenger vehicles.
• Inspect the anti‑return valve for proper operation; replace if leakage is detected.

Quality Assurance

The W9401 adheres to stringent European and automotive standards. It undergoes rigorous testing for:

• Particle retention efficiency.
• Pressure drop performance under load.
• Durability against temperature cycling and chemical exposure.

Environmental Considerations

Mann filters are designed with sustainability in mind. The W9401’s durable construction reduces waste, while its efficient filtration helps lower emissions by preserving engine performance.

Conclusion

The Mann Filter W9401 Lube Filter stands out as a reliable, versatile solution for protecting engines and hydraulic systems across a broad spectrum of vehicles and machinery.
