How to Specify Spin Pack Filter Disc

  • Shape: Round or annular discs to fit the pack body.
  • Layer build: Graded mesh layers, sometimes with sintered or fiber-felt layers.
  • Rim: Aluminum, stainless or welded double rims for a reliable seal.

Materials

Standard supply is stainless steel 304, 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

  • Fit new discs at every pack change and check rims for damage.
  • Assemble packs in a clean area to avoid contamination.

Common Mistakes

  • Re-using discs between pack changes, which releases trapped gels into the filaments.
  • Putting the fine layer on the upstream face, where it blinds within hours.

When Spin Pack Filter Disc Is Not the Right Choice

Not for bulk melt filtration upstream, where candle or leaf filters are used.
