High Flow Z - Absolute and Nominal

Z.Plex High Flow Z filters are advanced filtration solutions available in both absolute and nominal ratings, specifically designed for demanding applications in desalination, oil and gas, and other industrial markets. Manufactured using Veolia's proprietary two fiber construction and graded density matrix, these polypropylene melt-blown depth filters ensures superior particle retention throughout the entire filter diameter. Their enhanced dirt-holding capacity enables faster upset recovery and reduces surface blinding, surpassing the performance of most pleated filters. These USA-made filters deliver consistent, reproducible filtration quality with superior SDI reduction while requiring less frequent change-outs compared to conventional 2.5-inch outer diameter depth filters. The design results in lower total operational costs and more efficient filtration performance.
