PFA Lined Strainer: Features, Measurements & Materials

Purion9

The PFA Lined Strainer is built for demanding industries where highly corrosive, high-pressure, and high-temperature media need to be filtered. Its robust PFA lining offers exceptional resistance to aggressive fluids, making it ideal for sectors like chemical processing, water treatment, petrochemicals, and pharmaceuticals. Designed for easy maintenance and reliability, it features a replaceable filter basket, vacuum-tight sealing, and an option for conductive PFA to protect against electrostatic discharge. With its durable construction and high-efficiency filtration, the PFA Lined Strainer is the perfect solution for maintaining process integrity and minimizing downtime in critical operations.

Strainer Features

  • No Need for Drainage or Medium Disposal


    No need to drain the pipeline or dispose of residual media. Impurities are effectively removed as the strainer basket is pulled out, simplifying the process.

  • Easy Basket Cleaning & Exchange


    effortless cleaning or basket exchange without any contact with the medium, ensuring efficient maintenance while preventing contamination.

  • Meshing

    
ETFE filter mesh with mesh sizes from 85 to 2000my
Optional: Nickel alloy Element for temperatures > 150 °C

  • Sight Glass Add-On


    Dirt levels in the filter can be checked visually and to clearly determined the time for cleaning or replacement

  • Strainer Basket


    PTFE or Composite PTFE andCarbon filter element (available as spare part as well)

  • Non-Conductive PFA Version

    Our PFA Lined Strainer is available in a non-conductive version, designed for quick delivery and reliable performance in standard filtration applications.
