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.
