The F-DGSi’’s CO2 free air generators are some of the smallest and most efficient CO2 purifier systems for laboratory use, utilising a CO2 removal air dryer to remove CO2 less than 1 ppm.

This CO2 free air station is controlled using the latest in HMI touch screen technology to display the process in real time.

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.

Save money
The unit only requires connection to a suitable socket for model with integrated compressor .
The investment can be paid back in less than one year.

Improved safety
CO2 fee air 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.
