Original MANN-FILTER Air Filter C 25 003 – For Trucks, Buses and Utility Vehicles

Overview of the MANN‑FILTER Air Filter C 25 003

The MANN‑FILTER Air Filter C 25 003 is a high‑performance filtration solution engineered specifically for heavy‑duty applications such as trucks, buses and utility vehicles. Designed to meet the rigorous demands of commercial fleets, this filter delivers superior protection for engines while maintaining optimal airflow and fuel efficiency.

Key Design Features

• Robust Construction: The filter housing is constructed from durable polypropylene with reinforced seams, ensuring long life even in harsh operating environments.
• Advanced Filter Media: A multi‑layer cellulose and synthetic blend captures particles as small as 0.5 µm, providing exceptional protection against dust, grit, oil mist and other contaminants.
• Optimized Airflow: The media layout balances filtration efficiency with low pressure drop, preserving engine performance and reducing fuel consumption.
• Easy Installation: Standard dimensions (244 mm diameter) and a quick‑release mounting system allow for rapid replacement without special tools.

Performance Characteristics

The C 25 003 filter is engineered to maintain engine cleanliness under the most demanding conditions. Its performance metrics include:

• Filtration Efficiency: ≥ 99.5% for particles between 0.5–10 µm.
• Pressure Drop: ≤ 1.2 kPa at full airflow, ensuring minimal impact on engine load.
• Operating Temperature Range: –40 °C to +120 °C, suitable for extreme climates.

Compatibility and Applications

The filter is specifically tailored for a wide range of commercial vehicles. Common applications include:

• Heavy‑duty trucks (e.g., Volvo, Renault Trucks, Mack)
• City buses and transit coaches
• Utility vehicles such as delivery vans and construction equipment

Its standardized size allows it to fit seamlessly into existing filter housings across these platforms.

Installation Procedure

1. Prepare the Vehicle: Ensure the engine is cool and disconnect the battery for safety.
2. Remove Old Filter: Open the filter housing, release the retaining clips, and carefully remove the spent filter.
3. Inspect Housing: Clean any debris from the filter chamber to prevent contamination during installation.
4. Insert New Filter: Place the C 25 003 filter into the housing, aligning it with the airflow direction indicated by the arrow on the media.
5. Secure Housing: Reattach the clips and close the cover. Tighten to manufacturer specifications.
6. Reconnect Battery and Test: Start the engine and check for proper operation, ensuring no leaks or abnormal noises.

Maintenance Guidelines

To maximize filter life and performance, follow these maintenance steps:

• Inspect the filter every 10,000 km or after exposure to dusty environments.
• Replace the filter if it shows visible wear, discoloration, or a significant increase in pressure drop.
• Avoid cleaning the filter with water or solvents; replace instead of attempting to restore media integrity.

Benefits for Fleet Operators

• Extended Engine Life: By trapping fine particles, the filter reduces wear on pistons, valves and bearings.
• Improved Fuel Efficiency: Low pressure drop maintains optimal airflow, reducing engine load and fuel consumption.
• Reduced Emissions: Cleaner combustion leads to lower exhaust emissions, aiding compliance with environmental regulations.
• Cost Savings: Longer filter life and fewer maintenance visits translate into tangible operational savings.
