Compressed Air/Gas - Dryers

Finite® Compressed Air and Gas Desiccant DryersFinite® Compressed Air and Gas Desiccant Dryers

Finite Filter's unique in-line air/gas dryer system is engineered for easy desiccant changeouts, longer life and lower pressure drop. The FDD series is designed to remove water vapor and aerosols at point of use for intermittent flows up to 60 SCFM. Finte dryers do not require steady flow for constant dewpoint supression. A color changing mosture indicator with visual sight gauge indicates the desiccant needs replacement.


  • Zinc Head/Steel Bowl with Integral Sightglass
  • Sintered Bronze Elements (prevents desiccant carry over)
  • Collar Connect for Easy Changeouts
  • Maximum Operating Temperature: 180°F
  • Maximum Working Pressure: 300 PSI
  • Optimum Working Temperature: Below 100°F

Typical Applications:

  • Intermittent Air Use
  • Clean, Dry Air for Pneumatic Applications
  • Protect Instrumentation
  • Protect Air Tools Against Gumming and Oxidation
  • Auto Body Paint Systems - Helps Prevent Fish Eye Defects
  • Valve Actuation - Instrument Air
