Used Nitrogen Generators for Sale – Affordable, Reliable, and Fully Tested

At Air 2 Gas Tech, we maintain a limited inventory of used and refurbished nitrogen generators for sale, ideal for businesses seeking high performance without the high price tag. These units become available when customers upgrade to higher-capacity systems as their operational requirements evolve.

PSA Technology for Ultra-High Purity Nitrogen

Every system we offer is built around Pressure Swing Adsorption (PSA) technology, the industry standard for consistent, ultra-high purity nitrogen production. Using carbon molecular sieve (CMS), our generators deliver dependable results for applications across industries—from food packaging and laser cutting to electronics manufacturing and pharmaceutical processing.

Professionally Refurbished and Backed by Warranty

Before we offer any used nitrogen generator for sale, our technicians inspect, test, service, and refurbish the unit to ensure it performs within specification. We replace worn parts, clean internal components, and verify nitrogen output purity.

All refurbished units come with a 1-year warranty, providing peace of mind and dependable performance. On-site installation and commissioning are available upon request and handled by our experienced team.

Save Costs Without Compromising on Performance

Investing in a refurbished nitrogen generator is a smart way to lower your capital expenditure. Not only do you save money on the initial purchase, but you also avoid the steep depreciation that comes with buying new equipment. Each unit delivers the same nitrogen purity levels as a brand-new model—without the high price.

Support Sustainability with a Used Nitrogen Generator

Choosing a used nitrogen gas system also helps your business reduce its environmental impact By extending the lifecycle of industrial equipment, you’re actively lowering your carbon footprint while supporting a circular economy. Our commitment to sustainability means we prioritise quality, longevity, and responsible reuse.
