Engine Air Cleaner System

Cummins/Fleetguard OptiAir™ Air Cleaner

A remote mounted Cummins/Fleetguard OptiAir™ air cleaner provides the air filtering function. The paper filter element slides over an outlet tube inside the air cleaner canister with radial sealing action, eliminating the possibility of dust leaks due to improper filter installation. Intake design, internal baffling, and a dust ejection valve provide dust separation and automatic precleaning action. Daily or frequent servicing of the air cleaner is not required. Use the air restriction gauge on the air cleaner outlet to indicate when the air filter needs servicing -- a red flag will appear when the filter is overly restricting airflow into the engine.

IMPORTANT: Use only Cummins/Fleetguard air filter elements for replacement (Walker 2090-1 or 2090-3). Aftermarket filters may not seal properly or filter efficiently.
