Engine Air Cleaner System
Cummins/Fleetguard OptiAir™ Air Cleaner
A remote mounted Cummins/Fleetguard OptiAir™
air cleaner provides the air ltering function. The
paper lter element slides over an outlet tube inside
the air cleaner canister with radial sealing action,
eliminating the possibility of dust leaks due to
improper lter installation. Intake design, internal
bafing, 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 lter needs
servicing -- a red ag will appear when the lter is
overly restricting airow into the engine.
IMPORTANT: Use only Cummins/Fleetguard air
lter elements for replacement (Walker 2090-1 or
2090-3). Aftermarket lters may not seal properly or
lter efciently.
IMPORTANT: The Cummins/Fleetguard air cleaner
uses a dry paper-type air lter element. NEVER
apply oil to the paper element.
