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.
