Original MANN‑FILTER Fuel Filter WDK 724/1 – For Buses

The MANN‑FILTER Fuel Filter WDK 724/1 is a high‑performance, heavy‑duty filter engineered specifically for commercial bus engines. Designed to withstand the demanding operating conditions of large diesel and gasoline vehicles, this filter delivers reliable protection against contaminants while maintaining optimal fuel flow.

Key Design Features

• Robust Construction: The filter housing is made from reinforced steel with a corrosion‑resistant coating, ensuring durability in harsh environments and long service life.
• High Pressure Capability: Rated for pressures up to 10 bar (145 psi), the WDK 724/1 can handle the high fuel system pressures found in modern bus engines without compromising filtration efficiency.
• Large Filter Area: With a filter area of approximately 300 cm², it provides extensive surface for contaminant capture, reducing the risk of clogging and extending maintenance intervals.
• Precision Sealing: Dual O‑ring seals guarantee leak‑free operation even under vibration and temperature extremes typical in commercial transport applications.
• Easy Installation: The threaded mounting design (M10×1.5) allows for quick, tool‑less installation or removal, minimizing downtime during routine service.

Filtration Performance

The WDK 724/1 employs a multi‑layer filtration media that captures particles ranging from fine dust to larger debris. Its performance is characterized by:

• Particle Retention: Capable of filtering particles as small as 5 µm with a retention rate exceeding 99.9%.
• Low Pressure Drop: Maintains a pressure differential below 0.3 bar across the filter at full load, ensuring minimal impact on engine performance.
• Oil‑Free Operation: The media is engineered to prevent oil contamination of the fuel line, preserving injector integrity and combustion efficiency.

Applications and Compatibility

This filter is specifically tailored for bus engines but its robust design makes it suitable for a range of heavy‑duty vehicles, including:

• Diesel buses with high‑pressure fuel injection systems.
• Large gasoline-powered transit coaches.
• Commercial trucks and vans that operate under continuous load conditions.

It is compatible with most standard bus fuel lines featuring a 10 mm diameter, ensuring seamless integration into existing vehicle architectures.

Maintenance Guidelines

• Inspection Interval: Check the filter visually every 12 months or after 5,000 operating hours, whichever comes first.
• Replacement Schedule: Replace the filter at least once per year or when a pressure drop exceeding 0.3 bar is detected during operation.
• Cleaning Procedure: The filter should not be cleaned; it must be replaced to maintain optimal performance and avoid contamination.

Benefits for Bus Operators

• Enhanced Engine Longevity: By removing harmful particulates, the filter protects fuel injectors, pumps, and combustion chambers from wear.
• Improved Fuel Efficiency: A clean fuel system reduces friction and ensures consistent injector spray patterns, leading to better mileage.
• Reduced Downtime: The long service life and easy installation reduce maintenance time and costs.
• Reliability in Harsh Conditions: Designed for high temperatures, vibration, and corrosive environments typical of bus operations.

Technical Specifications

Conclusion

The MANN‑FILTER Fuel Filter WDK 724/1 is engineered to meet the rigorous demands of bus fleets. Its combination of durable construction, high filtration efficiency, and ease of maintenance makes it an essential component for ensuring engine reliability, fuel economy, and operational continuity in commercial transportation.
