Original MANN-FILTER Secondary Air Filter CF 400 – For Industrial, Agricultural and Construction Machinery

Overview of the MANN‑FILTER Secondary Air Filter CF 400

The MANN‑FILTER Secondary Air Filter CF 400 is a high‑performance filtration element designed for use in industrial, agricultural and construction machinery. It serves as an additional layer of protection for engines that operate in harsh environments, ensuring that only clean air reaches the combustion chamber.

Key Functionalities

• Dual‑Stage Filtration: The CF 400 incorporates a two‑stage filtration system that captures both large particulates and fine dust particles, extending engine life.
• High Flow Capacity: Engineered to maintain optimal airflow even under heavy load conditions, preventing pressure drops that could affect performance.
• Durable Construction: Made from premium synthetic fibers and reinforced with a protective casing, the filter resists abrasion, moisture, and chemical exposure.
• Easy Installation: Designed to fit standard secondary air intake assemblies without modification, allowing for quick replacement during routine maintenance.

Compatibility and Applications

The CF 400 is specifically tailored for a wide range of off‑highway equipment. It is compatible with major manufacturers such as ZETOR, FENDT, JOHN DEERE, PROXIMA, FARMER, and GT Series 5020. The filter is also suitable for machines in the AGROTRON series, as well as various Volvo models that require a 87 mm secondary air element.

Installation Guidelines

1. Preparation: Ensure the engine is cool and disconnect any power sources to avoid accidental startup.
2. Removal of Old Filter: Open the secondary air intake housing, carefully detach the existing filter, and discard it in accordance with local environmental regulations.
3. Installation of CF 400: Align the new filter with the mounting brackets. Secure it using the provided fasteners, ensuring a tight seal to prevent air leaks.
4. Reassembly: Close the housing, tighten all fittings, and verify that the filter is seated correctly.

Maintenance Recommendations

• Regular Inspection: Check the filter for visible signs of wear or clogging during scheduled maintenance intervals.
• Cleaning Procedure: If the filter becomes partially clogged, it can be cleaned with a low‑pressure air jet. Avoid using water or chemical cleaners that could damage the synthetic fibers.
• Replacement Interval: Depending on operating conditions, replace the CF 400 every 6,000–12,000 hours of engine time to maintain optimal filtration performance.

Performance Benefits

By incorporating the MANN‑FILTER Secondary Air Filter CF 400 into your machinery’s air intake system, you can expect:

• Extended Engine Longevity: Reduced particulate load translates to lower wear on pistons, valves, and bearings.
• Improved Fuel Efficiency: Cleaner airflow enhances combustion efficiency, potentially lowering fuel consumption.
• Lower Emissions: A cleaner air supply contributes to more complete combustion, reducing harmful exhaust emissions.

Technical Specifications

Conclusion

The MANN‑FILTER Secondary Air Filter CF 400 is a reliable and efficient component for any industrial, agricultural or construction machine that demands high air quality under demanding operating conditions. Its robust design, ease of installation, and proven performance make it an essential upgrade for operators seeking to protect engine integrity and enhance overall equipment efficiency.
