WITT gas filter LE6 protects downstream components and systems f rom contamination and condensates. Its size allows high flows with low pressure drop and compliance with the EIGA, AIGA and CGA maximum velocity limits.


  • ultra fine filtering out of mechanical impurities through bronze filter inserts
  • broad range of applications – compatible with many technical gases
  • change of filter possible while installed due to user-friendly design
  • high flowrate owing to flow-maximising design (4 500 Nm3/h for O2 at 30 bar and 50 mbar pressure drop)
  • condensates can be collected and removed using condensate drain
  • optimized design for easy installation and maintenance
  • extended flange connections for the simplest possible mounting of this heavy unit
  • connections on the inlet and outlet side to allow for pressure monitoring
  • reliable filtering performance increases service life of downstream components and equipment

Operation / Usage

  • Gas filters are designed for installation in pipelines
  • must be installed vertically


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


  • electronic differential pressure monitoring
