Original MANN-FILTER Air Filter C 31/1 – For utility vehicles

MANN‑FILTER Air Filter C 31/1

The MANN‑FILTER Air Filter C 31/1 is a high‑performance filtration solution specifically engineered for utility vehicles that demand reliable protection against dust, dirt and other airborne contaminants. Designed with precision engineering and rigorous testing standards, this filter delivers exceptional airflow while maintaining superior filtration efficiency.

Key Design Features

Optimized Airflow Path: The C 31/1 employs a multi‑layer construction that balances low resistance with high capture rates. This design ensures that the engine receives clean air without compromising performance or fuel economy.

Durable Filter Media: Constructed from premium synthetic fibers, the filter media resists clogging and retains its structural integrity even in harsh operating environments. The layers are engineered to trap particles as small as 0.5 µm, providing a high level of protection for critical engine components.

Robust Housing: The filter housing is made from reinforced plastic that resists impact, vibration and temperature extremes. Its sealed construction prevents moisture ingress, which could otherwise degrade filtration performance.

Installation & Compatibility

The C 31/1 is designed for a wide range of utility vehicles, including trucks, vans, and off‑road machinery. It fits standard filter housings that accommodate a 30 mm diameter opening with a 1 mm depth specification. The universal fitment allows mechanics to replace the filter quickly without requiring specialized tools.

Installation is straightforward: remove the old filter, clean the housing, insert the new C 31/1, and secure it with the provided gasket. A simple visual check ensures that the filter is seated correctly and that no gaps remain.

Performance Metrics

• Airflow Resistance: < 0.5 kPa at 100 m³/h, ensuring minimal impact on engine efficiency.
• Particle Capture Efficiency: >99.9% for particles ≥0.5 µm under standard testing conditions.
• Operating Temperature Range: –40 °C to +120 °C, suitable for extreme climates.
• Durability: Designed to last up to 10,000 km or 12 months in typical service intervals, depending on operating conditions.

Maintenance Guidelines

Regular inspection is essential to maintain optimal engine performance. Check the filter for visible signs of clogging or damage every 2,000 km or at each scheduled maintenance interval. If the filter appears dirty or has been exposed to harsh conditions (e.g., mud, oil spray), replace it immediately.

When replacing the C 31/1, always use a clean, dry cloth to wipe the housing and gasket area. Avoid using abrasive cleaners that could damage the seal or the filter media.

Environmental Impact

The MANN‑FILTER Air Filter C 31/1 is manufactured with sustainability in mind. The materials used are recyclable, and the production process adheres to strict environmental regulations. By ensuring efficient filtration, the filter helps reduce engine wear and emissions, contributing to a cleaner operating environment.

Applications Across Vehicle Types

The versatility of the C 31/1 makes it suitable for:

• Commercial delivery trucks that operate in dusty urban environments.
• Construction equipment such as excavators and loaders exposed to fine particulate matter.
• Agricultural machinery that must withstand soil dust and organic debris.
• Off‑highway vehicles used in mining or forestry operations where air quality is critical.

User Experience & Feedback

Operators report noticeable improvements in engine responsiveness after installing the C 31/1. The filter’s low resistance allows for smoother airflow, which translates into better acceleration and reduced fuel consumption. Additionally, many users note a longer interval between replacements compared to standard filters.

Technical Specifications

Conclusion

The MANN‑FILTER Air Filter C 31/1 stands out as a reliable, high‑performance filtration solution for utility vehicles operating in demanding environments. Its combination of low airflow resistance, superior particle capture, and durable construction ensures that engines remain protected, efficient, and long‑lasting. By choosing the C 31/1, vehicle operators can achieve optimal performance while maintaining compliance with environmental standards.
