What Is Photo-Etched Precision Filter Disc Used For?

Several thin photo-etched stainless steel filter discs with fine uniform hole patterns, one held up to light

Photo-Etched Precision Filter Disc (Custom to drawing (ISO 2768-f)) is specified where the duty calls for filtering, metering and diffusing fluids through thin stainless discs whose holes are chemically etched to an exact pattern — burr-free, stress-free and far more uniform than woven mesh. The sections below cover the typical end-uses by industry, the mesh, micron and material decisions for each, installation practice, and the applications this product type is not suited to.

Typical Applications for Photo-Etched Precision Filter Disc

Where Photo-Etched Precision Filter Disc is specified and bought:

  • Medical & analytical devices: inlet filters, flow restrictors and diffuser plates in pumps and analyzers.
  • Fuel & gas systems: last-chance screens in valves, regulators and injectors.
  • Consumer appliances: coffee machine, shaver and humidifier discs with exact flow.
  • Electronics: vent discs and EMI-shielded apertures.

How to Specify Photo-Etched Precision Filter Disc for Your Application

  • Hole size vs thickness: Etched holes are normally at least the sheet thickness; thinner foil allows smaller holes.
  • Pattern: Any hole shape, pitch and keep-out zone — supply a DXF so the tool matches your part exactly.
  • Material: SS304/316L, nickel, copper or titanium foil from 0.03 to 0.5 mm.
  • Standard: Quote Custom to drawing (ISO 2768-f) and the size designation from the table on the product page, plus any value you changed in the technical drawing.

Handling & Installation Practice

  • Handle thin discs with vacuum tweezers or by the rim; fingers bend them.
  • Specify the etch-entry face if hole taper matters for flow direction.

Common Selection Mistakes with Photo-Etched Precision Filter Disc

  • Asking for holes smaller than the foil thickness on a thick part.
  • Using an etched disc where the pressure drop needs a woven or sintered layer behind it for support.

Where Photo-Etched Precision Filter Disc Is Not the Right Choice

Not for very thick plates over about 1 mm, where punching, drilling or laser cutting is more economical.

If This Construction Is Not the Right Fit

Closely related mesh types for the same duty — compare open area, aperture range and cleanability before you commit.

Frequently Asked Questions

What is Photo-Etched Precision Filter Disc used for?

Filtering, metering and diffusing fluids through thin stainless discs whose holes are chemically etched to an exact pattern — burr-free, stress-free and far more uniform than woven mesh.

What is a photo-etched filter disc?

A thin metal disc whose holes are formed by chemical etching through a photo-resist mask, giving burr-free, uniform holes.

How small can etched filter holes be?

Down to roughly the foil thickness — about 0.05 mm in 0.05 mm foil.

Etched disc or woven mesh disc?

Etched discs give exact, repeatable holes and flat faces; woven mesh gives higher open area at lower cost.

Can I get a quote for Photo-Etched Precision Filter Disc to my own drawing?

Yes. Set the size and any custom value in the technical drawing on the product page and send it with the quote form; we reply within one business day.
