Gamma Gas nitrogen generators model selection

A whole system of PSA nitrogen generator has the following parts:

1 Air compressor;   2 Air treatment part;   3 Air tank;   4 Nitrogen separator;   5 Nitrogen buffer tank.

Air compressor, air treatment part, air tank and nitrogen buffer tanks are widely available in many countries. These parts are encouraged to be supplied from customers’ local suppliers. Gamma Gas only supplies the key part–nitrogen separator.

Below are nitrogen separators available in Gamma Gas.

NGB standard version model selection
This series nitrogen separators has lower cost, while compared with NGV series, this version requires higher compressed air consumption.
