Increased laboratory efficiency
A constant, uninterrupted gas supply of guaranteed purity eliminates interruptions of analyses to change cylinders and reduces the amount of instrument re-calibrations required.

Improved economy
Zero Nitrogen gas produced as standard

Improved safety
Zero Nitrogen produced at low pressure and ambient temperature removes the need for high pressure cylinders

Simple installation
Gas generators can be installed in the laboratory, on or under a bench, eliminating the need for long gas lines from cylinders secured elsewhere


  • Fully regenerative PSA technology ; reduced risk of gas contamination and phthalate free
  • Generates Nitrogen on demand from external compressed air
  • Catalyst module for hydrocarbons level (CH4)
    < 0.05 ppm
  • Designed to run 24 hours a day
  • Smart control of the flow of inlet air, it is function of the real flow of nitrogen used by the application
  • Minimum maintenance with an annual filter change
  • Remote PC monitoring via USB/RS232.
  • Ultra fast start-up time and fast purity
  • Compact and modular design
