Caterpillar Air Filter Replacement Maintenance Interval

The Cat air filter should be replaced or cleaned at least every 2000 hours or when the warning light is on. The outer filter element can be cleaned up to 6 times and then must be replaced. The inner filter element is a one-time item, which cannot

be cleaned and should be replaced directly. If the filter is damaged, it must also be replaced. Use clean, dry compressed air with a maximum pressure of 5 BAR for compressed air. Do not bring the nozzle closer to 3–5 cm. Blow the filter clean from

the inside along the pleats.
