schmidlin-DBS AG mini nitrogen generators use the pressure
swing adsorption (PSA) technique. The resulting stream of height
purity nitrogen gas 99.999% is ideal for applications including GC,
carrier gas, make-up gas, generally for most of the known flow
applications. This very quite and small device is a real table top unit
and equipped with on board air compressors, requires electric power only. Version 110 / 230 V 50/60 Hz.
