NEW HOLLAND 47135975 Secondary Engine Air Filter

The NEW HOLLAND 47135975 is a genuine OEM secondary engine air filter designed to provide critical backup protection within the air intake system of New Holland, Case IH, and Fiat agricultural machinery. Installed behind the primary air filter element, it serves as a safety barrier that protects the engine from harmful contaminants in the event of primary filter failure or improper installation. Unlike the primary filter, the 47135975 safety element is engineered specifically for engine protection rather than high dust-holding capacity. It remains in place during routine maintenance operations, ensuring that dust, debris, and airborne contaminants cannot enter the intake system when the outer filter is removed for inspection or replacement. The filter utilizes Radialseal technology with a molded urethane sealing surface that creates an airtight fit inside the air cleaner housing. This design minimizes vibration-related leakage and ensures maximum filtration integrity under demanding field conditions. As an additional safeguard, the safety element is intentionally designed to restrict airflow rapidly if significant contamination bypasses the primary filter. This allows operators to identify filtration system issues before contaminants can cause costly engine wear. Manufactured to genuine CNH specifications, the 47135975 helps protect pistons, cylinder liners, valves, turbochargers, and other critical engine components while supporting long-term reliability and machine uptime.
