Polygard Trap Filters

High-efficiency prefilter cartridges for removal of diatomaceous earth from beer

Lit No:DS1010EN00
Year:2004

For 45 years, Millipore has assisted beverage companies throughout the world with perfecting manufacturing operations and developing microbial management concepts for monitoring and removing microorganisms. Taking from this experience, we have developed the Polygard Trap Filters for removal of diatomaceous earth to ensure that you make the most of your manufacturing process. The graded density depth polypropylene Polygard Trap Filters have broad chemical (NaOH) properties, thermal compatibility and specific construction which makes them ideally suited to retain diatomite particles and PVPP fines. These cartridges provide high particle retention and offer a long lifetime. Unlike pleated pre-filter structures, the Polygard Trap Filters ensure long resistance to bleed-through.

  • 98% retention of hard particles over 2 µm
  • >99.99% retention of hard particles over 5 µm
  • Dual zone structure for extended useful life
  • No backwash required
  • Certificate of Compliance in each box
