New Holland 51586591 Cab Air Filter

The New Holland 51586591 is a genuine OEM cab air filter designed to maintain clean, healthy airflow inside the operator cabin. Installed within the HVAC ventilation system, it captures dust, pollen, airborne particles, and other contaminants before they enter the cab, helping improve operator comfort and visibility during long working hours. Manufactured to CNH Industrial specifications, this filter features a pleated filtration element combined with a protective foam layer that enhances particle retention while maintaining consistent airflow through the heating and air conditioning system. By preventing debris from reaching sensitive HVAC components, it helps protect blower motors, evaporators, and heater cores from premature contamination and performance loss. Designed for New Holland T4 and T5 Series tractors as well as selected Steyr models, the 51586591 provides reliable cabin air filtration and precise OEM fitment for demanding agricultural environments.
