NNZ10 filter element: specifications & equivalents

Q: What are the dimensions of the NNZ10 filter element?

The published envelope is 46 mm OD × 206 mm length with a 20 mm inside diameter (1.811 × 8.110 in × 0.787 in ID). Confirm against the housing drawing before ordering.

Q: What micron rating does NNZ10 use?

This element is rated 10 µm (nominal class) — 10 µm at β(c) ≥ 1000 (99.9% efficiency). Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.

The NNZ10 is a Schroeder Industries inline-line hydraulic filter element, built with excellement® z-media® (synthetic) media, sized 46 × 206 mm OD × length (ID 20 mm), rated at 10 µm class (10 µm at β(c) ≥ 1000 (99.9% efficiency)). Verify against the current manufacturer data sheet before ordering.

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).
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 NNZ10 filter element?

The published envelope is 46 mm OD × 206 mm length with a 20 mm inside diameter (1.811 × 8.110 in × 0.787 in ID). Confirm against the housing drawing before ordering.

What micron rating does NNZ10 use?

This element is rated 10 µm (nominal class) — 10 µm at β(c) ≥ 1000 (99.9% efficiency). Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.

What replaces the NNZ10 filter element?

5 partial match(es) requiring parameter review

How do I read the NNZ10 part number?

See the designation decoder above: each segment of NNZ10 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.
