Forklift Air Filter Assembly Selection
Choose the housing and its service elements as a documented combination. Airflow, restriction, sealing and outlet orientation matter alongside the element dimensions.
Air-filter element reference 1351230500, not a complete air-cleaner housing. Match the element and housing separately.
One element, two elements and two-stage cleaning are different descriptions
A single-element arrangement has a main filter without a safety element. A dual-element arrangement includes a main and a safety filter designed for that housing. “Two-stage” can instead describe a pre-cleaner followed by the main filter; it does not automatically mean two replaceable elements.
| Donaldson FPG housing | Primary element | Safety-element status | Selection boundary |
|---|---|---|---|
| G042544 / G042545 | P822686 | P535396 is designed to fit but not shipped as standard in the cited catalog | Adding it reduces maximum airflow; recalculate with the intended configuration |
| G057511 / G057512 | P821575 | P822858 is supplied in the cited catalog configuration | Keep the exact housing version and outlet direction |
| G057513 / G057514 | P821575 | P822858 is a designed optional element, not originally supplied | Same primary element does not make the housing configuration identical |
Compare the complete air-cleaner installation
An assembly request starts with the housing identity and the engine’s airflow and restriction requirement; an element request starts with the element reference and its housing relationship. Dimensions, seals, inlet/outlet direction and mounting then narrow the physical match. Close the order only against the confirmed housing and main/safety-element configuration, including whether an inner element is specified, rather than adding one because it appears to fit.
| Field | What to record | Why it matters |
|---|---|---|
| Airflow and restriction | Engine airflow requirement and permitted restriction; housing performance curve | Account for ducting, elbows and pre-cleaners, not only the element |
| Housing dimensions | Body diameter, overall length and service-removal clearance | The housing must fit and remain serviceable |
| Inlet and outlet | Diameters, direction, straight/elbow form and sealing connection | A similar cylindrical body may have a different installation |
| Elements | Main/safety references, OD, ID, height and seal profile | Dimensions support identification but do not replace the housing application |
| Mounting | Band/bracket position, spacing and orientation | Confirm the supported mounting arrangement |
| Dust valve and indicator | Valve type/orientation; indicator connection and setting | Use the housing/engine specification; no universal restriction setting |
H24C1-00211 identifies an assembly, not its unseen contents
The accompanying label reads H24C1-00211 and identifies an air-filter assembly. The housing and service-cover latches are visible. The picture does not reveal the element numbers, airflow rating or dimensions.
H24C1-00211 assembly reference. Internal element numbers and application remain to confirm; it is not identified as one of the Donaldson examples above. The source photograph cuts off part of the top edge; request a complete housing and port view for interface confirmation. View full photo
A safety element needs its own confirmed housing relationship
0830-G00 is separately identified as a secondary air filter element. Its presence here illustrates the service-item category; there is no confirmed pairing with H24C1-00211 or the Donaldson housings in the table. Never add an inner element simply because it appears to fit.

Start with whichever label you have
- For a complete assembly, send the housing label and installed inlet/outlet views.
- For a replacement element, send its number and both sealing ends; include the housing number if known.
- If the number is unreadable, provide dimensions with units and an overall photo. A photo-only inquiry is welcome, but it does not automatically confirm compatibility.
Ask about the part you need
A part number is optional. Start with the information you have.
