Original MANN-FILTER Interior Filter CU 4150 – For Trucks, Buses and Utility Vehicles

Product Overview

The MANN‑FILTER Interior Filter CU 4150 is a high‑performance cabin air filter designed specifically for heavy‑duty vehicles such as trucks, buses and utility vehicles. It delivers superior protection against dust, pollen, smoke and other airborne contaminants, ensuring that the interior environment remains clean and healthy for drivers and passengers alike.

Key Features

• Advanced Filtration Technology: Utilises a multi‑layer media system that captures particles as small as 0.3 µm with high efficiency, protecting the cabin from allergens and pollutants.
• Durable Construction: Made from reinforced polypropylene housing that resists abrasion and moisture, extending the filter’s service life even in harsh operating conditions.
• Easy Installation: Designed for quick replacement without special tools. The snap‑fit design allows technicians to install or remove the filter within minutes.
• Wide Compatibility: Fits a broad range of commercial vehicle models, including many Volvo, Mercedes-Benz, Scania and MAN chassis. Refer to the specific model list for exact fitment.
• Low Pressure Drop: Maintains optimal airflow through the HVAC system, ensuring efficient climate control without compromising engine performance.
• Eco‑Friendly Materials: Manufactured with recyclable components and minimal VOC emissions during production.

Performance Benefits

The CU 4150 filter significantly improves cabin air quality by trapping fine dust, pollen, smoke particles, and even some chemical vapors. This leads to:

• Enhanced Driver Comfort: Cleaner air reduces irritation of eyes, nose, and throat, especially important for long‑haul drivers.
• Reduced HVAC Wear: By preventing contaminants from reaching the heating, ventilation, and air conditioning (HVAC) system, the filter helps maintain the longevity of blower motors and compressors.
• Lower Maintenance Costs: The robust design reduces the frequency of replacements compared to standard filters, saving time and resources over the vehicle’s lifetime.
• Improved Fuel Efficiency: A low pressure drop ensures that the engine does not have to work harder to maintain cabin airflow, contributing marginally to fuel savings.

Installation Guide

1. Locate the Cabin Air Filter Compartment: In most commercial vehicles, this is situated behind the glove box or under the dashboard on the passenger side.
2. Open the Cover: Use a flathead screwdriver or your fingers to release the latch and lift the cover away from the filter housing.
3. Remove the Old Filter: Gently pull the existing filter out of its slot. Dispose of it according to local environmental regulations.
4. Insert the CU 4150: Align the filter’s airflow arrows with the vehicle’s airflow direction and slide it into place until it clicks securely.
5. Close the Cover: Snap the cover back onto the housing, ensuring a tight seal to prevent air leaks.
6. Verify Functionality: Start the engine and check that the HVAC system operates normally. No unusual noises or reduced airflow should be present.

Maintenance Tips

• Inspect the filter every 12,000–15,000 km or after exposure to dusty environments; replace if visibly clogged.
• Avoid forcing a damaged filter into place; this can damage the housing and compromise cabin air quality.
• Keep the filter compartment clean from debris before installation to prevent contamination of the new filter.

Compatibility Matrix

The CU 4150 is engineered for a wide array of heavy‑duty platforms. Below are representative vehicle families that accept this filter:

• Volvo: Buses, trucks and utility chassis.
• Mercedes-Benz: Sprinter, Vito, and heavier commercial models.
• Scania: Heavy truck series and passenger vans.
