Polygard Trap Cartridge Filters

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

Description

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.

Typical Applications

Trap filtration is a necessary step to retain diatomite particles and PVPP fines after the diatomite filter clarification and PVPP stabilization. Particulate and microbiological purity are essential to the consistency and the quality of the beer. Trap filtration brings safety and reliability to these process steps. The Polygard Trap filter is an ideal high capacity prefilter used in the brewing process.

Certificate of Compliance

Each Polygard Trap cartridge filter is shipped with a Certificate of Compliance for documentation accuracy. This document certifies that the component materials meet FDA Indirect Food Additive requirements cited in 21 CFR 177 –182 and that product was designed and manufactured to stringent specifications assuring its suitability for demanding beverage filtration applications.
