German KSI Filtertechnik ECOTROC GEN2 (nitrogen) and GEO2 (oxygen) are PSA generators producing gas on-site from compressed air for a range of applications. Both series come in Comfort and Premium types. GEN2 delivers nitrogen at purities up to 99.999% (residual oxygen down to 1.0 ppm) with capacity of roughly 0.9–105 Nm³/h; a membrane technology is also available for some applications (0.14–54 Nm³/h at purities up to 99.5%). GEO2 delivers oxygen at purities up to about 93–95%. Premium versions include a multilingual touch-control panel, remote control via iPad and PC, long-term data storage, inlet/outlet filtration as standard, continuous purity measurement, and automatic restart for medical applications.
