Perkins 26510353 + 26510354 Air Filter Kit – OEM Primary & Safety Set

Dual-stage defense — This kit combines the primary air filter 26510353 and the safety element 26510354. The filter size: 423*208*106mm

Where it’s used — Perkins 1000/1006-series gensets 135 kVA–150 kVA and forklift engines. Both drop into the same housing—just make sure the canister is clean and the seal surfaces are clear before installing.

Cross-reference bridges — For mixed inventories, these map to parts like Donaldson P777638 / P777639, Baldwin RS3884 / RS3885, Fleetguard AF25492 / AF25491, and more.

Tech tip — Avoid blowing old filters clean—they lose efficiency fast. Swap as a pair during scheduled service: install the outer filter first, seat firmly, then insert the safety element. Log the date; that keeps airflow clean and thermals steady.
