In 1996, two family-owned Memphis-based companies combined operations to form nexAir. By merging Mid-South Oxygen Company (founded in 1946) and Standard Welders Supply/Standard Oxygen Service (founded in 1940), nexAir became the second-largest privately owned distributor of gases and welding supplies in the United States.Today nexAir is a supplier of high-quality industrial, specialty, medical, and bulk gases, dry ice, welding equipment, welding supplies, and medical equipment. With strategically placed retail locations, nexAir can be responsive to each customer's specific needs. We draw on the expertise of hundreds of experienced salespeople, welding analysts, cryogenic technicians, and medical-equipment specialists to provide solutions that save time and money. From strong regional support to local decision-making, nexAir delivers performance under pressure.
