How the HC2238FCN6H model number is decoded
- HCPall hydraulic cartridge element platform.
- 2238Housing envelope / configuration block — this execution fits HYDAC 0330/0500 return-filter housings per Pall’s interchange list.
- FCRed1000 (Coralan SRT media) element configuration code.
- NMedia grade: 7 µm at βx(c) > 1000 per ISO 16889. P=5, N=7, S=12, T=22 µm.
- 6Nominal element length: 6 inches.
- HSeal / end-cap execution for the matched HYDAC housing; verify seal compound in the Pall data sheet for the fluid medium.
Typical equipment & applications
- Tank-mounted return-line hydraulic filters
- Hydraulic power units and lubrication systems
- Construction and agricultural machinery
- Machine tool and industrial hydraulic systems
Selection pitfalls — read before you substitute
- A return-line element is not a pressure-line element: return cartridges (BN4HC low-collapse) tolerate roughly 20 bar differential, while BH4HC pressure executions are rated to 210 bar. Installing a low-collapse element in a pressure housing can rupture the media on cold-start spikes.
- This element has no integral bypass — opening pressure is set by the housing’s reusable bypass valve. Confirm the valve setting (commonly 3.4 bar) is present before fitting.
- “10 µm nominal” and “12 µm at β1000” can describe the very same media — one is reported at β≥200, the other at β≥1000 per ISO 16889. Compare ratings at the same Beta test point, not just the printed micron number.
- Nitrile (NBR) seals are standard for mineral hydraulic oil but fail early in some phosphate-ester fluids and at sustained high temperature; verify seal compound against the fluid data sheet (fluorocarbon/Viton executions may be required).
- End-cap geometry and the number/position of O-rings block interchange even when OD and length match — visually compare end caps before fitting, especially with aftermarket cartridges.
Frequently asked questions
What micron rating does HC2238FCN6H use?
This element is rated 7 µm absolute — β7(c) > 1000 per ISO 16889. Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.
What replaces the HC2238FCN6H filter element?
1 catalog-confirmed full match(es) (0330 R 005 BN4HC)
How do I read the HC2238FCN6H part number?
See the designation decoder above: each segment of HC2238FCN6H encodes size, line type, filtration grade and media/collapse execution.
Is a same-envelope aftermarket element always a drop-in replacement?
No. Matching OD and length only proves the cartridge fits the bowl. End-cap style, seal compound, micron/Beta rating, collapse pressure and bypass configuration must also match; the table above tags every equivalent as full, partial or verify for exactly this reason.
How often should a hydraulic return-line element be replaced?
Replace at the housing manufacturer’s recommended differential-pressure setting (commonly signalled by a clogging indicator), or on a time-based service interval when no indicator is fitted — never wait for bypass to open continuously, because unfiltered oil then reaches the valves.
