Mann C 33 1840 Air Filter, 327mm OD, 191mm ID, 483mm Height

Mann C 33 1840 Air Filter

The Mann C 33 1840 Air Filter is a high‑performance, OEM‑grade filtration solution designed for heavy‑duty commercial vehicles. It delivers superior protection for the engine’s intake system by trapping contaminants while maintaining optimal airflow.

Key Dimensions and Fitment

• Outer Diameter (OD): 327 mm – ensures a snug, direct fit on the intake manifold.
• Inner Diameter (ID): 191 mm – accommodates the inlet port of most heavy‑duty engines.
• Height: 483 mm – provides ample filter media for extended service intervals.

These precise measurements make the filter compatible with a wide range of Mercedes-Benz and Setra models, including Actros MP2/MP3, NG, SK, Travego, and SETRA 300 series. The cartridge design allows for quick installation without the need for additional hardware.

Construction and Materials

The filter is constructed from a multi‑layer media system that combines:

• Pre‑filter layer: captures large particles, extending the life of the main filter.
• Main filtration core: engineered with high‑density fibers to trap fine dust and debris.
• Back‑pressure control: maintains low resistance to airflow, preserving engine efficiency.

All materials are certified for use in diesel engines, ensuring durability under high temperatures and pressure conditions typical of commercial operations.

Performance Benefits

• Enhanced Engine Protection: By removing up to 99.9% of airborne contaminants, the filter protects pistons, valves, and fuel injectors from wear.
• Improved Fuel Economy: Low back‑pressure design reduces engine load, contributing to better mileage.
• Extended Service Intervals: The robust media can last longer between changes compared to standard filters, reducing maintenance downtime.
• Consistent Airflow: Maintains optimal air supply for combustion, ensuring reliable engine performance even in dusty environments.

1. Turn off the engine and allow it to cool completely.
2. Remove the existing filter cartridge by loosening the retaining clips or screws.
3. Clean the filter housing with a dry cloth to remove any debris.
4. Insert the new Mann C 33 1840 filter, aligning it with the mounting points.
5. Secure the cartridge using the original clips or screws; ensure a tight seal.
6. Start the engine and check for any leaks or abnormal noises.

For vehicles equipped with an electronic air‑filter monitoring system, reset the sensor after installation to avoid false alerts.

The filter meets all Mann Filter quality standards and complies with ISO 9001 certification. It is engineered to match or exceed OEM specifications for Mercedes-Benz and Setra engines, guaranteeing that the intake system receives the same level of protection as when it was new.

• Inspect the filter regularly for visible clogging; replace if media appears saturated.
• Avoid using water or harsh chemicals to clean the housing, as these can damage seals.
• Store spare filters in a dry, dust‑free environment to preserve their integrity.

The combination of precise engineering, durable materials, and proven performance makes the Mann C 33 1840 Air Filter an ideal choice for fleet operators seeking reliability and cost‑effective maintenance. Its direct fitment on a broad range of heavy‑duty engines eliminates compatibility concerns, while its high filtration efficiency protects critical engine components over extended periods.

Investing in the Mann C 33 1840 Air Filter means prioritizing engine longevity, fuel efficiency, and operational uptime. Its meticulous design and robust construction ensure that every vehicle it serves receives top‑tier protection against airborne contaminants, keeping engines running smoothly for years to come.
