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,
reducing the possibility of dust leaks due to improper
lter installation. Intake design, internal ba󰀪ing, and
a dust ejection valve provide dust separation and
automatic precleaning action. Daily or frequent
servicing of the air cleaner is not required.
IMPORTANT: Use only Cummins/Fleetguard air
lter elements for replacement (Walker 2090-1 and
2090-3). Aftermarket lters may not seal properly or
lter e󰀩ciently.
IMPORTANT: The Cummins/Fleetguard air cleaner
uses a dry paper-type air lter element. NEVER
apply oil to the paper element.
