WITT gas filters for reliable protection against contamination and condensate.


  • ultra-fine filtering out of mechanical impurities through bronze or stainless steel filter inserts
  • broad range of uses – compatible with many technical gases
  • filter inserts in stainless steel with a filtering fineness of approx. 0,5 µm, approx. 10 µm or approx. 40 mµ
  • filter inserts in bronze especially for O2 with a filtering fineness of 5 µm or 50 mµ, according to EIGA
  • change of filter possible while installed due to user-friendly design
  • high flowrate thanks to flow-maximising design
  • condensate can be collected and removed using condensate drain
  • easy to install thanks to large choice of connections
  • reliable filtering performance increases service life of downstream fittings and equipment
  • withstands maximum line pressure (50 bar) even if it becomes clogged

Operation / Usage:

  • particularly well suited to use in laser systems
  • Gas filter model 77 is designed for installation in pipelines
  • the gas purifiers with condensate drain must be installed vertically


  • the condensate should be drained at regular intervals
  • the filter inserts must be checked regularly and replaced if necessary
