Air Filters

Air filtration is where Pakistani operating conditions are hardest on equipment. An engine draws hundreds of cubic metres of air an hour, and every bit of it goes through the element.

Air filters are the only one of the four types with no bypass valve, and that is deliberate: it is better for an engine to be starved of air than fed unfiltered air. So a blocked air filter announces itself through lost power and black smoke rather than quietly going out of circuit.

Two seal types appear below and they are not interchangeable even where the dimensions look close. An axial seal clamps flat between the housing and the cover. A radial seal seals on its inside diameter against the housing neck. Check which one your cleaner takes.

Where a housing holds a second, inner element, that safety filter has its own number and its own interval — the AF424 pairs with the AF820M, for instance. More in choosing the correct air filter and air filter troubleshooting.

The Perkins numbers are listed differently from the rest, and deliberately. Perkins publish fitment by engine rather than by dimension, so each card leads with the engine series and the exact models the part is fitted to. That is how a Perkins buyer identifies a filter anyway: from the engine plate, not from a tape measure. If you have the engine number, send it and we will match the part to it.

The three Perkins elements below cover most of the range between them: 26510337 for the 100 and 400 Series and smaller 1100 engines, 26510342 for the 1104 and 4.236, and 26510353 for the six-cylinder 1006, 1106 and 1206. They are primary elements, so check whether your housing also takes a safety element behind it.

Numbers we stock

11 air filter numbers we are asked for most often, across Fleetguard and Perkins. Our range is far wider than this — if your number is not listed, it is very likely we can still supply it or match an equivalent.
