  • high mixing accuracy
  • avoids the need to stock multiple pre-mixes (cost-saving)
  • does not require a receiver (cost- and space-saving)
  • inlet gas filters protect the device against impurities
  • pneumatic operating principle, no electrical connections required
  • mixed gas production from 8 l/min to the max. flow
  • robust, compact design
  • panel for wall mounting
  • minimal maintenance required

Easy operation:

  • blends are factory-set and tamper-proof (FIX)

High process reliability:

  • independent of pressure fluctuations in the gas supply
  • independent of withdrawal fluctuations (in permitted range)
  • fail-safe design (unit shuts down on failure of either gas supply)


  • alarm module NXT : integrated inlet pressure monitoring with digital display for pressure (with analogue pressure transmitters) plus optical alarm, adjustable alarm limits, the obligation of  acknowledgement, protection of alarms, interfaces for controlling external alarms etc. – electrical connections required

Other models, options and accessories available upon request. Please identify the individual gases at the time of enquiring!

Our gas mixers are always customised to the needs of the customer. Please tell us your specifications, we will realise them.
