Original MANN-FILTER Interior Filter CU 4466 – For trucks

Overview of the MANN‑FILTER Interior Filter CU 4466

The MANN‑FILTER Interior Filter CU 4466 is a high‑performance cabin air filter designed specifically for heavy‑duty trucks and commercial vehicles. It delivers superior protection against dust, pollen, smoke, and other airborne contaminants, ensuring that the driver’s environment remains clean, healthy, and comfortable.

Key Design Features

• Robust Construction: The filter housing is made from durable polypropylene, providing resistance to moisture, abrasion, and chemical exposure typical in truck cabins.
• High‑Efficiency Media: Utilizes a multi‑layer filtration media that captures particles as small as 0.3 µm with an efficiency of up to 99.5 %.
• Low Pressure Drop: Engineered to maintain airflow while minimizing resistance, which helps preserve HVAC system performance and fuel economy.
• Easy Installation: The filter features a simple snap‑fit design that allows for quick replacement without the need for tools or specialized equipment.

Performance Specifications

Compatibility and Application

The CU 4466 is engineered for a wide range of commercial truck models, including but not limited to:

• Iveco Eurotanker series
• Mercedes-Benz Actros and Arocs
• Volvo FH and FMX
• Scania R-series
• Daimler Freightliner Cascadia

It is suitable for both diesel and gasoline engines, as well as hybrid powertrains that require cabin air filtration.

Installation Procedure

1. Locate the Cabin Air Filter Compartment: Typically found behind the glove box or under the dashboard on the passenger side.
2. Remove the Old Filter: Open the compartment cover, release any clips or screws, and slide out the spent filter.
3. Insert the New CU 4466: Align the filter with the airflow direction arrow and snap it into place until secure.
4. Reassemble the Compartment: Replace the cover and fasten any clips or screws.
5. Verify Airflow: Start the vehicle and ensure that the HVAC system operates normally with no unusual noises.

Maintenance Guidelines

• Inspect the filter every 12,000 km (or as recommended by the vehicle manufacturer) for visible dust accumulation.
• Replace the filter if airflow resistance increases or if the cabin interior feels noticeably dusty.
• Avoid cleaning or reusing the filter; it is a disposable component designed for single use.

Health and Environmental Benefits

The CU 4466 significantly reduces exposure to airborne pollutants, which can improve driver concentration, reduce fatigue, and lower the risk of respiratory issues. By maintaining cleaner cabin air, the filter also contributes to a more pleasant driving experience during long hauls.
