    Why does my WALKER FILTRATION PROSFD have a poor dewpoint?
    • M
      melissa81Aug 19, 2025
      If your WALKER FILTRATION Dryer shows a poor dewpoint, several factors could be responsible. There might be liquid water at the dryer inlet, so you should check the pre-filtration and drains. It's also possible that the flow is exceeding the maximum specified, or that the inlet pressure or temperature are not within specifications, so check these against their specifications. Other potential causes include a blocked or damaged silencer (in which case, replace it), air leaks (tighten joints or fit new seals), or incorrect dryer operation (consult the electrical operation troubleshooting section).
