Perkins 2652C845 Primary Air Filter
The Perkins 2652C845 primary air filter is the outer element for Perkins 1100 and 1200 series engines, paired with a 2652C847 safety element behind it. Which element your build actually calls for is a serial question, not a number question, and the two are not interchangeable.

Confirm the position, not just the number
The FF5636 is a spin-on fuel element, with the element and housing combined in one canister. It is listed for the engine-side fuel position on Cummins ISC and ISL builds, downstream of the water separator.
Catalogues disagree on whether to call it a primary or secondary filter. Confirm the installed position and complete old part number against your engine build before ordering.
Engine model & build
Provide the engine maker, model and full serial or build number. The model name alone does not confirm fitment.
Installed filter position
Identify the filter head it came from and whether a water separator sits upstream.
Complete old part number
Send the full number printed on the removed element, including any suffix. If the records disagree, send all three for review.
2652C845 Cross-References Are Candidates, Not Confirmations
The 2652C845 crosses to a set of numbers across brands. Treat each as a candidate to check against the engine serial and the installed position. A dimensional match alone does not confirm media, seals or flow.

| Donaldson | P780522 | Cross-listed primary element (also P812924) |

1100 Series, 1200 Series, or a 1004 Build: Reconcile by Serial
Perkins names the 2652C845 a “1200 and 1100 series” air filter. That dual name is useful but not the whole story. The recovered model list reaches 1104D-E44T and 1104D-E44TA, the 1204E, 1204F and 1204J variants, and a 1004-42 build used in a Claas Targo telehandler.
So the part spans three model families under a two-series label. The series name narrows the candidates; it does not settle the fit. Confirm the engine maker, model and full serial, plus the engine prefix (MK, ML, MT, MU, NH, NJ, NP, NR, ST or SU).
Watch the Baldwin numbers closely. RS3971 and RS5334 both appear on the primary side, while RS5335 sits on the safety side for the 2652C847. A one-digit slip between RS5334 and RS5335 lands the wrong element.

Perkins 1100 / 1200 Series
We do not republish retailer dimensions. The ~395 mm length, ~185 mm outside diameter and ~105 mm inside diameter that appear on seller pages vary between listings, and a copied dimension is not evidence. Dimensions are confirmed against the manufacturer specification for the build when we quote.
The 2652C845 is the primary element; the 2652C847 is the safety element.

Request a QuoteFrequently Asked Questions
What does the Perkins 2652C845 fit?
It is the primary air element for Perkins 1100 and 1200 series engines, with model lists also reaching 1104D, 1204E/F/J and a 1004 build. Confirm by engine serial and prefix.
Is the 2652C845 the same as the 2652C847?
No. The 2652C845 is the primary (outer) element and the 2652C847 is the safety (inner) element. The two are paired but not interchangeable.
Is the 2652C845 a primary or safety element?
Primary. It is the outer, first-line element in the intake system; the safety element behind it is the 2652C847.
What does the 2652C845 cross to?
Candidate references include Donaldson P780522, Baldwin RS3971, Fleetguard AF25957, WIX 42330, MANN C 19460/2 and HIFI SA 16229. Treat each as a candidate to check.
Will the 2652C845 fit my Perkins engine?
Only the build and the parts record confirm that. Send the engine serial and the number off the element you are replacing.
Confirm the Number, Then Confirm the Element
The Perkins 2652C845 primary air filter is quoted against a build and an installed element, in that order: the number finds a candidate element, and the serial and the primary/safety position decide. Send the engine model, serial number, and the number off the element you are replacing, plus which position it came from. We will confirm the offered element, its maker, complete number and delivery terms, and the safety partner if your build carries one.
