Additionally, it features a compact, multi-dimensional design that fits seamlessly into Caterpillar’s engine compartments, as well as compatible machinery from other brands. Moreover, it supports an extensive list of cross-reference part numbers, making it a versatile replacement option for fleets, repair shops, and equipment owners worldwide.
Caterpillar, a global leader in heavy machinery and engine technology, designs the 4N0015 to meet its strict OEM standards. Furthermore, it is built to withstand the demanding operating conditions of construction, mining, and marine applications—where dust, dirt, and debris pose constant threats to engine health. For this reason, it becomes a trusted choice for anyone seeking reliable, long-lasting air filtration for their Caterpillar equipment.
Unlike generic air filters that fail to match Caterpillar’s precision, the 4N0015 is tailor-made for the 3406 and 3208 engines. It also fits other high-demand machinery, including Kleemann Reiner MRB 122 Z, ensuring broad compatibility and exceptional value.
Superior Filtration Efficiency & Engine Protection
The CAT 4N0015 air filter boasts an impressive 99.9% filtration efficiency, trapping nearly all airborne contaminants that can damage engine components. Specifically, it captures fine dust, metal particles, and sediment, preventing them from entering the engine’s combustion chamber and causing premature wear.
This level of precision is critical for Caterpillar’s 3406 and 3208 engines, which are relied on for heavy-load operations. In addition to contaminant removal, the filter maintains consistent airflow, ensuring the engine receives the clean air it needs to optimize combustion and power output. Moreover, it reduces strain on engine components, extending the overall service life of the engine.
Consequently, the 4N0015 not only protects the engine but also minimizes unplanned downtime and costly repairs. It delivers long-term value by keeping Caterpillar equipment running smoothly, even in the harshest environments.
Precise Dimensional & Physical Specifications
The CAT 4N0015 features carefully calibrated dimensions to ensure a perfect fit with compatible Caterpillar engines and machinery. First and foremost, its length measures 396.7 mm (15.62 inch), width 381 mm (15.00 inch), and height 141.5 mm (5.57 inch)—a compact, multi-dimensional design optimized for Caterpillar’s engine compartments.
Additionally, the filter weighs 4.180 kg, reflecting its durable construction and high-quality materials. Its volume is 0.024320 m³, making it lightweight enough for easy installation while still maintaining the robustness needed for heavy-duty use. These dimensions align perfectly with OEM specifications, eliminating fitment issues and ensuring a secure, leak-proof seal.
Moreover, its compact size makes it suitable for a range of applications, from on-road trucks to off-road construction equipment. This versatility further enhances its value for fleets with mixed machinery.
Extensive Cross-Reference Part Numbers
The CAT 4N0015 air filter is compatible with a wide range of cross-reference part numbers, expanding its usability across multiple brands. Specifically, these include AC DELCO A1072C, AMERICAN PARTS 94580, APCO AA163, and BERGERAT MONNOYEUR E2231.
Other key cross-references include BIG A 1550, CATERPILLAR 4N15, CHRYSLER 1852569, CONTINENTAL PCA2571, and COOPERS AEP3515. This extensive list simplifies inventory management for repair shops, as it reduces the need to stock multiple filter models.
Furthermore, it matches DONSSON DA6237, FORD 9576P150135, GUARDIAN G4N0015, HESCO 4N0015, and NELSON 83893N, ensuring operators can easily find a replacement regardless of the original part number or brand.
Multi-Brand Equipment Compatibility
The CAT 4N0015 is primarily designed for Caterpillar engines, including the 3208 (67U1->, 78Z1->), 3406, 3408 C (1TS1->, 67U1->, 78Z1->, 99U1->, 9ER1->, TAM1->), 3412GE, and 300 CAT SS models. These engines are widely used in heavy trucks, construction equipment, and industrial applications.
Beyond Caterpillar, it also fits Kleemann Reiner MRB 122 Z, a popular piece of construction machinery. Additionally, its cross-compatibility with Ford, Chrysler, and Onan equipment means it can serve as a universal replacement filter for mixed fleets, further enhancing its versatility.
Moreover, it suits National Oilwell, Orenstein & Koppel, Wirtgen, and Walgahn-Motorentechn equipment, making it a go-to solution for a wide range of industrial and construction needs.
CAT 4N0015 Durability & Heavy-Duty Performance
The CAT 4N0015 is built to withstand the rigors of heavy-duty operation. Its robust construction resists physical damage, engine vibration, and environmental exposure—common challenges in construction, mining, and marine settings.
Unlike low-quality aftermarket filters, it maintains structural integrity even in extreme temperatures and high-dust environments. This durability reduces filter replacement frequency, lowering long-term maintenance costs. Moreover, its high-quality filter media resists clogging, ensuring consistent airflow and filtration performance over its service life.
Additionally, its OEM design ensures seamless integration with Caterpillar engines, preventing air leaks and ensuring maximum protection. This reliability makes it a trusted choice for operators who depend on their equipment for daily operations.
