Two Elements, One Housing
Buyers ordering the air filter for a Zaxis ZX200 usually quote one number and come looking for a second the following week. The housing takes an outer primary element, 4286128 at 371 mm high and 237 mm outside diameter, and an inner safety element, 4286130 at about 352 mm high and 133 mm outside diameter. The two are not interchangeable and neither substitutes for the other: the outer does the filtering, and the inner is the backstop that catches what gets past the outer while the outer is open, badly seated or already failed.
Both elements cross over cleanly to the filter brands — Baldwin RS3538 and RS3535, Donaldson P821938 and P821963, Fleetguard AF25414 and AF25412, MANN C24553 and CF1414, WIX 46776 and 46640 — which is the easiest way to check availability in your own market before you order from China.
The Air Cleaner Does Not Change With the Engine
Where the fuel filter number changes between the 6BG1 generation (ZX200, ZX200LC-E, ZX210H) and the 4HK1X generation (ZX200-3, ZX200LC-3, ZX210H-3), the air cleaner pair does not. Application data for 4286128 and 4286130 carries ZX200 and ZX200LC-E on 6BG1 alongside ZX200-3 and ZX200LC-3 on 4HK1X, and the same pair continues through ZX210LCH-3, ZX225US, ZX230, ZX240-3, ZX250LC-3, ZX270-3 and ZX280LCH-3.
That makes the pair a sensible shelf item: one air cleaner set covers a mixed fleet of early and common-rail ZX200-series machines on the same site, which is worth knowing when a contractor runs both generations of the same model.
Dust Is a Cost, Not a Nuisance
The air cleaner is the one filter on these machines that protects the most expensive component in the shortest time. A ZX200 working a crusher feed, a quarry face or a dry-season haul road pulls that dust cloud through the intake all day, and the difference between a specification-grade element and the cheapest one that fits the housing is measured in the life of a turbo and the cylinder bores behind it. Two habits matter: order the pair so there is no gap where the outer element has been removed, and never blow out the inner element to make it last longer — compressed air drives the retained dust deeper into the media, so the element looks clean and passes dirt.
What We Do Not Publish
No price, because the honest variables are quantity, specification level and shipping lane. No hour interval, because Hitachi sets servicing by machine, duty cycle and site conditions rather than in a public table, and an invented interval causes real damage. And no claim about filter efficiency percentages that we cannot show you from a published source. What we do publish: the numbers, the dimensions, the cross-references, and a warning if you are about to fit the wrong element.
FAQ
Q: What is the air filter number for a Hitachi ZX200?
A: The air cleaner on a ZX200 takes two elements: Hitachi 4286128 as the outer primary element, published at 371 mm high, 237 mm outside diameter and 131 mm inside diameter, and Hitachi 4286130 as the inner safety element at about 352 mm high and 133 mm outside diameter. Aftermarket equivalents are Baldwin RS3538 (outer) and RS3535 (inner), Donaldson P821938 and P821963, Fleetguard AF25414 and AF25412, MANN C24553 and CF1414, WIX 46776 and 46640. Always quote the pair, not the outer element alone.
Q: Does 4286128 fit a ZX200-3 with the Isuzu 4HK1X engine?
A: Yes. Application data for the pair carries both engine generations against the same elements: ZX200 and ZX200LC-E on the Isuzu 6BG1, and ZX200-3 and ZX200LC-3 on the Isuzu 4HK1X. That is unlike the fuel filter, which changes number between the two generations. If your machine is a ZX200-3 or ZX200LC-3, the air cleaner pair is 4286128 with 4286130.
Q: Do I need the inner element 4286130 as well as the outer 4286128?
A: Yes, they are a pair in one housing. The inner safety element exists to catch dust that reaches the intake while the outer element is being changed, or after an outer element fails or is fitted badly. It should not be cleaned and blown out with compressed air — that drives retained dust deeper into the media and returns a filter that looks new and passes dirt. Order the pair for any machine working in dust.
Q: Which other machines use the same air filter pair?
A: Supplier application data for 4286128 and 4286130 carries the same air cleaner on machines outside the Hitachi badge: Case CX210B and CX210C, Kobelco SK200-8 and SK210LC-8, John Deere 210CW and 245GLC, Linkbelt 210 X2 and 240 LX, New Holland E225B SR and Sumitomo SH240-3, all on Isuzu engines. If you run a mixed fleet, this makes the pair a shared shelf item. Catalogue application lists are a fitment reference rather than proof of fit — confirm against your machine serial.
Order the Pair, Not Half the Air Cleaner
Tell us the model — ZX200, ZX200-3, ZX210H-3, ZX230, ZX240-3 or ZX270-3 — or send a photo of the old elements beside a tape measure. We confirm 4286128 with 4286130, add the hydraulic element and fuel cartridge on the same order if you want the service set, and ship in 3–7 days, FOB Shanghai or CIF to your port.
