At Filtry.org you will find air filters matched to ONAN industrial machines.
A clogged air filter restricts airflow, reducing engine power and increasing fuel consumption. That is why replacing air filters every 15,000-30,000 km or 250-500 engine hours is one of the most important service tasks. Every air filter at Filtry.org can be looked up by ONAN OEM number or cross-reference.
All air filters for ONAN available at Filtry.org include cross-reference numbers and full technical documentation.
In passenger cars every 15,000-30,000 km. In construction and agricultural machines every 250-500 engine hours or as indicated by the restriction sensor. In high-dust environments the interval may be halved.
Yes. A clogged filter restricts airflow, upsetting the fuel mixture ratio. The engine compensates with increased fuel injection, raising consumption by 5-15%.
The primary (outer) element captures most contaminants. The safety (inner) element protects the engine during primary filter changes and if the outer element is damaged.
