Original MANN-FILTER Air Filter CF 970 - Secondary Air Filter Element – For utility vehicles

Product Overview

The MANN‑FILTER Air Filter CF 970 is a high‑performance secondary air filter element designed specifically for utility vehicles and commercial applications. It serves as an essential component in the vehicle’s exhaust gas recirculation (EGR) system, helping to reduce emissions and improve engine efficiency.

Key Functionalities

• Efficient Filtration: Captures fine particulate matter from exhaust gases before they enter the catalytic converter, ensuring optimal catalyst life.
• Low Pressure Drop: Maintains a minimal pressure differential across the filter, which reduces engine load and preserves fuel economy.
• Durable Construction: Made with high‑grade materials that resist corrosion and thermal degradation under harsh operating conditions.
• Easy Installation: Designed to fit standard secondary air filter housings in a wide range of commercial vehicles without the need for custom modifications.

Technical Specifications

Compatibility and Installation Guidance

The CF 970 is engineered to fit seamlessly into the secondary air filter assemblies of a broad spectrum of commercial vehicles, including:

• Light-duty trucks and vans with inline‑4 or inline‑6 engines.
• Medium‑size delivery vehicles equipped with diesel or gasoline powertrains.
• Commercial fleets that require stringent emission controls.

Installation typically involves removing the existing filter element, aligning the CF 970 within the housing, and securing it with the provided retaining clips. For optimal performance, ensure that all seals are intact and that the filter is seated correctly to prevent air leaks.

Performance Benefits

• Emission Reduction: By filtering exhaust gases before they reach the catalytic converter, the CF 970 helps lower NOx and particulate emissions in compliance with modern environmental regulations.
• Engine Longevity: Protects downstream components from abrasive particles, thereby extending the life of the catalyst and other emission control devices.
• Fuel Efficiency: The low pressure drop minimizes additional work required by the engine, contributing to modest fuel savings over time.
• Reliability: Consistent performance across a wide temperature range ensures dependable operation in varied climates and driving conditions.

Maintenance Recommendations

Although the CF 970 is designed for durability, regular inspection is advised to maintain peak efficiency:

1. Visual Check: Inspect for visible signs of wear or contamination during routine vehicle servicing.
2. Pressure Test: Perform a pressure drop test at the recommended flow rate to verify that the filter remains within specified limits.
3. Replacement Interval: Replace the element after a predetermined mileage or time period as dictated by the vehicle manufacturer’s maintenance schedule, typically ranging from 20,000 to 40,000 miles for commercial fleets.

Environmental Impact

The CF 970 contributes to greener operations by reducing harmful emissions. Its efficient filtration process helps meet stringent emission standards such as Euro 6 and EPA Tier 4, supporting fleet operators in achieving compliance while maintaining performance.

Conclusion

The MANN‑FILTER Air Filter CF 970 stands out as a reliable, high‑quality secondary air filter element tailored for utility vehicles. Its blend of robust construction, low pressure drop, and proven emission control capabilities makes it an indispensable component for commercial fleets seeking to balance performance with environmental responsibility.
