Original MANN-FILTER Air Filter CF 75/2 – Secondary Air Filter Element – For Utlity Vehicles

MANN‑FILTER CF 75/2 Secondary Air Filter Element

The CF 75/2 is a high‑performance secondary air filter designed for utility vehicles and industrial machinery. It serves as an additional layer of protection, capturing fine particulates that may bypass the primary filter. This element enhances engine longevity, improves fuel efficiency, and ensures compliance with stringent emission regulations.

Key Design Features

• Optimized Geometry: The CF 75/2 features a precisely engineered airflow path that balances filtration efficiency with minimal pressure drop. This design reduces engine load while maintaining superior dust capture.
• Durable Filter Media: Constructed from high‑grade cellulose and synthetic fibers, the media offers excellent resistance to abrasion, chemical attack, and temperature variations typical in heavy‑duty applications.
• Robust Housing: The element is encased in a reinforced plastic shell that protects against impact, vibration, and moisture ingress. The housing includes secure mounting tabs compatible with standard filter frames.
• Easy Installation: Designed for quick replacement, the CF 75/2 fits into most existing secondary filter housings without modification. Its standardized dimensions (approx. 62 mm diameter) match a wide range of utility vehicle models.

Performance Characteristics

The CF 75/2 delivers exceptional filtration across a broad particle size spectrum:

The element maintains a pressure drop of less than 5 kPa under normal operating conditions, ensuring that engine performance is not compromised.

Applications and Compatibility

• Utility Vehicles: Trucks, vans, and light commercial vehicles equipped with diesel or gasoline engines.
• Industrial Machinery: Construction equipment such as excavators, loaders, and compactors that require robust air filtration.
• Agricultural Implements: Tractors, combine harvesters, and other farm machinery where dust and particulate matter are prevalent.

The CF 75/2 is engineered to fit a variety of manufacturers’ secondary filter housings. Common compatibility includes models from Volvo, Kawasaki, Hyundai, Mahindra, and many others that use the standard CF 75/2 mounting interface.

Installation Procedure

1. Safety First: Ensure the engine is cool and the vehicle is parked on a level surface. Disconnect the battery if necessary to prevent accidental start‑up.
2. Remove Old Filter: Open the secondary filter housing, release any retaining clips or screws, and carefully lift out the worn element.
3. Inspect Housing: Clean the interior of the housing with a dry cloth to remove dust or debris that could compromise seal integrity.
4. Insert CF 75/2: Align the new filter with the mounting tabs and slide it into place. Secure any clips or fasteners according to the vehicle’s specifications.
5. Verify Seal: Check for proper seating of the element; there should be no gaps between the housing and the filter media.
6. Reassemble: Close the housing cover, tighten any screws or bolts, and reconnect the battery if it was disconnected.

Maintenance Guidelines

• Inspect the secondary filter at least once every 10,000 km (or as recommended by the vehicle manufacturer).
• Replace the CF 75/2 when visual inspection reveals significant dust accumulation or media degradation.
• Avoid cleaning the filter with water or solvents; such actions can damage the media and reduce filtration efficiency.
• Store spare filters in a dry, cool environment to preserve material integrity.

Benefits of Using CF 75/2

• Extended Engine Life: By trapping fine particulates before they reach the combustion chamber, the filter reduces wear on pistons, valves, and bearings.
• Improved Fuel Economy: Lower pressure drop means less engine effort is required to draw air, translating into measurable fuel savings over time.
• Emission Control Compliance: High filtration efficiency helps meet or exceed emission standards such as Euro 6 and EPA Tier II.
• Reduced Maintenance Costs: Fewer contaminants mean less frequent cleaning of downstream components like the catalytic converter.

Material Composition

The CF 75/2’s filter media is a composite blend of cellulose fibers and synthetic polymers. This combination offers:

• High porosity for efficient airflow.
• Excellent mechanical strength to withstand vibration.
• Resistance to oil, fuel, and other automotive fluids.

Environmental Impact

By capturing airborne particulates before they exit the vehicle’s exhaust system, the CF 75/2 contributes to reduced air pollution. Its durable construction also means fewer replacements are needed over the vehicle’s lifespan, lowering overall material consumption.

Conclusion

The MANN‑FILTER CF 75/2 Secondary Air Filter Element is a reliable, high‑performance solution for utility vehicles and industrial machinery. Its robust design, superior filtration efficiency, and ease of installation make it an essential component for maintaining engine health, achieving fuel savings, and meeting environmental standards.
