F-DGS’’s TOC Air generators are some of the smallest and most efficient Hydrocarbon-free air and CO2 purifier systems for laboratory use. Utilising a heated catalyst technology which is combined with a CO2 removal air dryer to remove THC including methane to less than 0.05 ppm and CO2 less than 1 ppm.

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

Better detector performance
The reduction of CO and hydrocarbons, including methane to < 0.05 ppm decreases the background noise level and gives the baseline much better stability, considerably increasing detector sensitivity and ensuring precise analytical results. Reduce also CO2 level to < 1 ppm for TOC and Electronic noise applications.

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

TOC air produced at low pressure and ambient temperature removes the need for high pressure cylinders

Security of supply
Do not requires external 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
