The F-DGSi’s range of laboratory Nitrogen Gas Generators are some of best designed PSA Nitrogen Gas Generators available.

Utilizing the reliable and efficient PSA technique of separating Nitrogen and Oxygen is used to produce high quality Nitrogen Gas at various flows and purities (see performance data).

The Generator is controlled using the latest in HMI touch screen technology to display the process in real time, inlet/outlet pressures and oxygen level (optional).

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
Pure nitrogen gas produced as standard

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

Security of supply
Integral oil free air compressor as an option guarantees continuous gas supply, independent of in house compressed air supply

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
