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
bafing, 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 lter restriction gauge on the
air cleaner outlet to indicate when the air lter needs
servicing -- a yellow indicator will show when the
lter is overly restricting airow into the engine.
IMPORTANT: Use only Cummins/Fleetguard air
lter elements for replacement (Walker 2090-1 and
2090-3). Aftermarket lters may not seal properly or
lter efciently.
IMPORTANT: The Cummins/Fleetguard air cleaner
uses a dry paper-type air lter element. NEVER
apply oil to the paper element.
