0250 DN 020 BH4HC filter element: specifications & equivalents

Q: What are the dimensions of the 0250 DN 020 BH4HC filter element?

The published envelope is 80 mm OD × 250 mm length with a 40.1 mm inside diameter (3.150 × 9.843 in × 1.579 in ID). Confirm against the housing drawing before ordering.

Q: What micron rating does 0250 DN 020 BH4HC use?

This element is rated 20 µm absolute — βx(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.

The 0250 DN 020 BH4HC is a HYDAC pressure-line hydraulic filter element, built with betamicron 4 microglass, high-collapse (210 bar / 3045 psi) media, sized 80 × 250 mm OD × length (ID 40.1 mm), rated at 20 µm absolute (βx(c) ≥ 1000 per ISO 16889). Verify against the current manufacturer data sheet before ordering.

Selection pitfalls — read before you substitute

Line type is not interchangeable: return-line cartridges are low-collapse executions that typically tolerate roughly 10–20 bar differential, while pressure-line elements are commonly rated 100–210 bar. Installing a low-collapse element in a pressure housing can rupture the media on cold-start spikes.
“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.
This execution uses nitrile (nbr) seals — verify the compound against the fluid data sheet: standard nitrile (NBR) can fail early in phosphate-ester fluids and at sustained high temperature, where 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 are the dimensions of the 0250 DN 020 BH4HC filter element?

The published envelope is 80 mm OD × 250 mm length with a 40.1 mm inside diameter (3.150 × 9.843 in × 1.579 in ID). Confirm against the housing drawing before ordering.

What micron rating does 0250 DN 020 BH4HC use?

This element is rated 20 µm absolute — βx(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 0250 DN 020 BH4HC filter element?

Cross references are being verified for this model — use the inquiry form and the engineering desk will confirm equivalents.

How do I read the 0250 DN 020 BH4HC part number?

See the designation decoder above: each segment of 0250DN020BH4HC 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 filter 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.
