Original MANN-FILTER Secondary Air Filter CF 300 – For Industrial, Agricultural and Construction Machinery

Original MANN‑FILTER Secondary Air Filter CF 300

The MANN‑FILTER Secondary Air Filter CF 300 is a high‑performance filtration solution engineered for demanding industrial, agricultural and construction machinery applications. Designed to operate in harsh environments, this filter delivers reliable protection against dust, grit, oil mist and other contaminants that can compromise engine performance and longevity.

Key Design Features

• Robust Construction: The filter housing is made from durable polypropylene with reinforced seams to withstand vibration, impact and exposure to chemicals commonly found in off‑road operations.
• Optimized Filtration Media: A multi‑layer media stack provides superior particle capture while maintaining low airflow resistance. This balance ensures efficient engine breathing without sacrificing power output.
• Extended Service Life: The CF 300 is engineered for extended intervals between changes, reducing maintenance downtime and operational costs in heavy‑duty environments.
• Wide Compatibility: Available in a range of sizes (77 mm, 80 mm, 90 mm) to fit numerous engine models across the MANN‑FILTER catalog, including popular brands such as Volvo, Massey Ferguson, JCB and Nissan.

Performance Characteristics

The filter’s performance is quantified by two critical parameters: filtration efficiency and pressure drop. The CF 300 achieves a filtration efficiency of up to 99.9 % for particles as small as 5 µm, while maintaining a pressure drop below 0.3 kPa at standard operating conditions. These figures translate into:

• Reduced Engine Wear: By trapping fine particulates before they reach the combustion chamber.
• Improved Fuel Economy: Lower resistance allows the engine to operate closer to its optimal airflow curve.
• Enhanced Emission Control: Cleaner intake air supports more complete combustion, reducing harmful exhaust emissions.

Installing the CF 300 is straightforward. The filter’s snap‑fit design eliminates the need for additional fasteners, while the clear indicator window allows operators to monitor wear visually. For routine maintenance:

1. Inspect: Check for visible damage or clogging of the media.
2. Clean (if applicable): Some models support a rinse‑and‑reuse cycle; consult the specific product data sheet before attempting.
3. Replace: When pressure drop exceeds manufacturer specifications, replace with a new CF 300 to restore optimal performance.

The versatility of the CF 300 makes it suitable for a broad spectrum of machinery:

• Construction Equipment: Excavators, bulldozers and backhoes that operate in dusty construction sites.
• Agricultural Machinery: Tractors, combine harvesters and sprayers exposed to soil particles and crop residue.
• Industrial Vehicles: Forklifts, loaders and material handling units used in warehouses and manufacturing plants.
• Specialized Off‑Road Applications: Mining rigs, forestry equipment and heavy-duty transport vehicles that encounter abrasive environments.

The CF 300 is available in multiple dimensions to match a wide array of engine types. Below is an illustrative compatibility list (not exhaustive):

The CF 300 adheres to stringent European standards for filtration performance, including EN 1458 and ISO 8577-1. Each unit undergoes rigorous testing for pressure drop, particle retention and chemical resistance before shipment. The filter’s design also complies with environmental regulations governing particulate emissions from heavy machinery.

By ensuring cleaner intake air, the CF 300 contributes to lower exhaust pollutant levels. Its extended service life reduces waste generation compared to filters that require frequent replacement. Additionally, the filter’s materials are recyclable, supporting circular economy initiatives within the heavy‑equipment sector.
