How the 1320 D 003 BH4HC model number is decoded

  • 1320Element size code (1320) for the HYDAC DF/DFF pressure-filter housing family.
  • DPressure-line element for HYDAC DF/DFF pressure filter housings.
  • 0033 µm absolute class per the HYDAC electronic catalog (s2).
  • BH4HCBetamicron 4 microglass, high-collapse (210 bar / 3045 psi)

Typical equipment & applications

  • Pressure-line hydraulic filters upstream of control valves
  • High-differential-pressure industrial hydraulic circuits
  • Hydraulic power units for steel, paper and power generation

Selection pitfalls — read before you substitute

  • “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).
  • Fine 3 µm media loads faster and runs at a higher cold Δp than coarser grades — only downgrade cleanliness targets if the system ISO 4406 code allows it.
  • 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 1320 D 003 BH4HC filter element?
The published envelope is 91 mm OD × 650 mm length (3.583 × 25.591 in). Confirm against the housing drawing before ordering.
What micron rating does 1320 D 003 BH4HC use?
This element is rated 3 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 1320 D 003 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 1320 D 003 BH4HC part number?
See the designation decoder above: each segment of 1320D003BH4HC 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.
