Questions about nitrogen?
Whether you need gas or liquid nitrogen, find the right supply mode for your needs
Packaged gas
We offer nitrogen in high-pressure gas cylinders and liquid nitrogen cylinders — available in a variety of sizes — to meet any small to medium volume needs.
MicroBulk and Bulk
For those who have outgrown cylinders but lack space for bulk storage, we offer nitrogen through Airgas MicroBulk packaging — a safe, clean and efficient solution for higher-volume users.
Nitrogen is also available in bulk gas and liquid delivery — as well as in a full range of purities and tank sizes. And it is available through ECO ORIGIN™, which offers certified, low-carbon bulk liquid nitrogen gas to help reduce your emissions in Scope 3.
FLOXAL™ on-site gas generation
For those who regularly consume gas in large volumes from 10 to 1000s Nm3/H, we offer the FLOXAL on-site gas generation system. FLOXAL makes gas generation reliable and efficient by providing an uninterrupted gas supply with consistent flow rates and purity.
Need help determining the right right quantity for your application? Complete the form and tap into our expertise for any standard or custom application, including innovative gas equipment and technologies designed to help you safely deliver your gas to the point of use, wherever you are.
Food Processing
From chilling to freezing to packaging, nitrogen plays an important role throughout the entire food production process. In addition to its cooling properties, nitrogen also increases shelf life for food products in modified atmosphere packaging (MAP), keeping oxygen out and freshness in. It is also used in grain silos to create a controlled atmosphere that can help prevent spoilage and maintain grain quality.

Manufacturing & Metal Fabrication
Nitrogen is used as an effective way to prevent oxidation and provide a safe, inert atmosphere that “sweeps” off gases produced by furnaces. It’s also used as an assist gas for laser cutting and enhances plasma cutting.

Additive Manufacturing: Nitrogen is used in a variety of additive manufacturing applications, from powder production, storage and transport to powder reuse, 3D printing and post processing. Learn More Learn more
Aerospace & Defense: Using nitrogen while manufacturing quality components is a safe practice commonly used throughout the aerospace industry. An inert gas, nitrogen eliminates the presence of oxygen and secures a nonflammable environment. Nitrogen is also used in heat-treating furnaces, wind tunnels and laser-cutting applications.

Automotive: Nitrogen is used as both a safety component in airbags and as a versatile welding gas in automotive manufacturing. It’s used in a diverse range of assembly line tasks because it provides a good atmosphere for welding with any material. Nitrogen can also be used to inflate tires in place of compressed air which helps to maintain pressure longer and improve tire life. Learn more
Chemicals: Nitrogen is used to pressurize pipelines in order to help propel liquids and to help purge piping and equipment to prevent contamination. Through Airgas Nitrogen Services, we offer quality nitrogen backed by a constant, consistent supply from mobile nitrogen pumpers. Learn more
Construction: Along with its use in welding, liquid nitrogen is also used when working with concrete in hot weather. Our CryoCrete™ and ChillRight™ concrete cooling processes use liquid nitrogen as an alternative to traditional cooling methods. We also offer nitrogen for welding. Learn more
Life Sciences: As a gas, nitrogen is used as an essential component in various life science processes as well as a protectant against oxidation and contamination. In liquid form, nitrogen is also used to achieve cryogenic temperatures in cooling applications such as reactor and MRI magnets. Learn more
Oil and Gas: Nitrogen is used in a wide range of upstream, midstream and downstream applications. It can be used for everything from testing pipeline pressure to purging air to managing temperature to turnarounds and maintenance to lightening liquids for better flow. Learn more
