EconoGen is a compact plug-and-play nitrogen generator that reportedly eliminates reliance on outside sources for cylinders. Consists of two filter beds of carbon molecular sieve. While preheated compressed air enters the bottom of the first bed and passes across the sieve, oxygen and trace gases are absorbed as nitrogen is allowed to pass through to enter a low-pressure storage tank. As one bed becomes saturated, the second bed automatically activates and takes over the separation process. Remains operative until N2 production requirements are met or the storage tank is filled. Is offered in two series, with Series 1 systems used in low- to high-volume applications, while Series 2 generators are for laboratory, prototyping or benchtop applications.
