Product Introduction
The AF55005 air filter is a rectangular primary engine air filter designed for heavy-duty diesel engines and off-road equipment. Its high-capacity cellulose media captures dust, sand and other airborne contaminants before they enter the engine intake system.
The reinforced plastic frame supports the filter media under vibration and demanding working conditions. Its direct-flow design provides stable airflow while helping reduce premature engine wear.

Product Case
A construction-equipment distributor required replacement filters for diesel machines operating in a dusty work environment. The original air filters became heavily loaded, resulting in increased intake restriction and reduced engine airflow.
After replacing them with compatible AF55005 primary air filters, the machines achieved more stable intake airflow and improved dust protection. Regular inspection and timely replacement also helped reduce unplanned maintenance and supported reliable engine operation.
