MANN‑FILTER CF 820 Secondary Air Filter
The CF 820 is a premium secondary air filter engineered by MANN‑FILTER for use in industrial, agricultural and construction machinery. Designed to provide optimal airflow while trapping fine particulates, it ensures the longevity of engines and compliance with stringent emission regulations.
Key Design Features
- High‑Efficiency Filtration Media: Utilises a multi‑layer fibrous matrix that captures particles as small as 0.5 µm, protecting downstream components such as catalytic converters and exhaust gas recirculation (EGR) valves.
- Robust Construction: Encased in a durable polypropylene housing with reinforced edges to resist abrasion and impact during heavy‑load operations.
- Optimised Airflow Path: The filter geometry is engineered for minimal pressure drop, maintaining engine performance while delivering clean air.
- Wide Compatibility: Fits a broad range of OEM models including Fendt, AGCO, BOMAG, CLAAS and other off‑highway vehicles. Detailed fitment charts are available from MANN‑FILTER technical support.
- Easy Installation: The CF 820 features a quick‑release mounting system that allows for rapid replacement without the need for special tools.
Applications in Industrial Machinery
The secondary air filter is critical in industrial engines where exhaust gases are recirculated to reduce NOx emissions. By ensuring clean intake air, the CF 820 helps maintain optimal combustion efficiency and reduces wear on catalytic systems.
Agricultural Use Cases
- Tractors, combines and sprayers often operate in dusty environments; the CF 820’s high‑efficiency media protects sensitive engine components.
- Its low pressure drop is essential for maintaining power output during heavy field operations.
- Compatibility with Fendt and AGCO models makes it a go-to choice for farmers seeking reliable performance.
Construction Machinery Integration
Excavators, loaders and bulldozers rely on secondary air filters to keep EGR systems functioning correctly. The CF 820’s robust housing withstands the vibration and impact typical of construction sites, while its efficient filtration preserves engine life.
Maintenance Guidelines
- Inspect the filter every 6,000–10,000 hours or as recommended by the vehicle manufacturer.
- Clean the outer housing with a damp cloth; avoid using solvents that could damage the polypropylene shell.
- Replace the filter when visual inspection reveals clogging or when performance drops are observed.
Environmental Impact
The CF 820 contributes to lower emissions by ensuring that secondary air is free from contaminants, thereby improving the efficiency of catalytic converters. Its design aligns with global efforts to reduce particulate matter and NOx in industrial exhaust streams.
