1700 R 010 BN4HC filter element: specifications & equivalents

The 1700 R 010 BN4HC is a HYDAC return-line hydraulic filter element, built with betamicron 4 microglass (bn4hc) media, rated at 10 µm class (β12(c) ≥ 1000 per ISO 16889 (10 µm at β ≥ 200)). Verify against the current manufacturer data sheet before ordering.

Filtration rating 10 µm nom.
Beta rating β 12(c) ≥ 1000 per ISO 16889 (10 µm at β ≥ 200)
Media Betamicron 4 microglass (BN4HC)
Collapse / burst 20 bar
Line type return
Partially verified. Fit and grade trace to an official interchange document; dimensional values are compiled from 0 aftermarket listing(s) and must be confirmed against the manufacturer housing drawing. Confidence score 0.75.

Envelope dimensions (OD/ID/length) are pending extraction from the HYDAC Betamicron catalog (s3); grade, media and collapse ratings are confirmed. Verify the housing drawing before ordering.

How the 1700 R 010 BN4HC model number is decoded

  • 1700Element size code for the HYDAC RF/RFM return-filter housing family (1700 size).
  • RReturn-line element (installed in a tank-top return filter).
  • 010Filtration grade code: 10 µm class (12 µm(c) at β ≥ 1000 per the ISO 16889 multipass convention used in Pall’s interchange list).
  • BN4HCBetamicron 4 microglass media, low-collapse execution (~20 bar collapse pressure) with nitrile seals; BH4HC is the 210 bar high-collapse variant.

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 1700 R 010 BN4HC use?
This element is rated 10 µm (nominal class) — β12(c) ≥ 1000 per ISO 16889 (10 µm at β ≥ 200). Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.
What replaces the 1700 R 010 BN4HC 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 1700 R 010 BN4HC part number?
See the designation decoder above: each segment of 1700R010BN4HC 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.
