Mann Filter WDK925 Fuel Filter

Mann Filter WDK925 Fuel Filter

The WDF925 Fuel Filter is a high‑performance component engineered by MANN‑FILTER, one of the world’s leading manufacturers of filtration solutions for commercial vehicles. Designed specifically for heavy‑duty trucks, buses and other commercial applications, this filter delivers superior protection against contaminants that can damage engines, fuel pumps and injectors.

Key Design Features

• Robust Construction: The filter housing is made from durable steel with a reinforced gasket system to withstand the high pressures typical of commercial fuel systems.
• High Flow Capacity: Engineered for low pressure drop, it allows maximum fuel flow while still trapping fine particles, ensuring optimal engine performance and longevity.
• Advanced Filtration Media: Utilizes a multi‑layer media stack that captures particles as small as 1 µm, protecting sensitive fuel injection components from wear and clogging.
• Wide Compatibility: Fits a broad range of DAF, MAN, Scania, Volvo, Mercedes-Benz and other heavy‑duty chassis models. The filter is available in multiple pressure ratings (75 CF, 85 CF, 95 CF) to match specific vehicle requirements.
• Easy Installation: Screw‑on design with a quick‑release feature allows for rapid replacement without the need for specialized tools or extensive disassembly.

Performance Specifications

Installation Guide

1. Preparation: Ensure the vehicle’s fuel system is depressurized and the engine is cool.
2. Remove Old Filter: Unscrew the existing filter using a suitable wrench. Carefully detach any hoses or fittings, noting their orientation for reassembly.
3. Install New Filter: Align the screw threads with the fuel line and tighten by hand until snug. Use a torque wrench to achieve the manufacturer’s recommended torque (typically 12 Nm).
4. Reconnect Hoses: Attach any hoses or fittings, ensuring they are seated correctly to prevent leaks.
5. Check for Leaks: Start the engine and observe the filter area for any signs of fuel leakage. Tighten further if necessary.

Maintenance & Replacement Interval

The Mann Filter WDK925 is designed to last through extensive mileage, but regular inspection is essential. For most commercial fleets, a replacement interval of 30,000 km or 12 months (whichever comes first) is recommended. However, operators experiencing high particulate loads—such as those in dusty or gravelly environments—may need to replace the filter more frequently.

Benefits for Commercial Operators

• Engine Protection: By trapping contaminants before they reach the fuel injectors and pumps, the filter extends engine life and reduces costly repairs.
• Fuel Efficiency: A clean fuel system operates more efficiently, leading to better mileage and lower operating costs.
• Reduced Downtime: The quick‑release design allows for rapid replacement, minimizing vehicle downtime during maintenance windows.
• Compliance with Emission Standards: Clean fuel contributes to reduced exhaust emissions, helping fleets meet stringent environmental regulations.
