Where Etched Micro-Slot Filter Screen Is Used

  • Fuel & hydraulic valves: slot filters that fit inside compact valve and injector bodies.
  • Medical devices: slot screens in infusion pumps and catheters.
  • Beverage dispensers: micro-slot strainers on syrup and water lines.
  • Instrumentation: sensor-port and sampling screens.

How to Specify Etched Micro-Slot Filter Screen

  • Slot width: 0.05–0.2 mm — the width, not the length, sets particle retention.
  • Slot length & pattern: Longer slots raise open area; staggered rows keep the sheet stiff.
  • Foil: 0.05–0.2 mm SS316L, with slot width at least equal to foil thickness.

Materials

Standard supply is stainless steel 316/316L; the material column in the table and the drawing options show the exact grade for each size. Other alloys and finishes can be quoted to your drawing.

Fitting & Care

  • Orient slots as the flow design requires; slots across the flow drain better.
  • Clean ultrasonically in a mild detergent, never with a wire brush.

Common Mistakes

  • Specifying slots narrower than the foil thickness, which etching cannot produce cleanly.
  • Ignoring slot orientation when forming the screen into a cup or tube.

When Etched Micro-Slot Filter Screen Is Not the Right Choice

Not for coarse straining, where punched perforated sheet is cheaper.
