reat Lakes Air GN2-250A15-XP0 Nitrogen Generator – 99.99% Purity, 145 PSI Feed Pressure | High-Capacity PSA System
Reference: GN2-Brochure-2010-1
The Great Lakes Air GN2-250A15-XP0 is a high-capacity PSA Nitrogen Generator engineered for demanding industrial applications requiring ultra-high nitrogen purity (99.99%) at a 145 PSI compressed air feed pressure. This system uses Pressure Swing Adsorption (PSA) technology with Carbon Molecular Sieve (CMS) to selectively remove oxygen and deliver a steady stream of nitrogen gas, reducing dependency on bulk nitrogen supply and lowering operational costs by up to 92%.
