Our customer’s success begins and ends with one thing: A Focus on People.

When you have a partner and supplier that you trust, you have the confidence to create the future you envision for your company.

nexAir is a family-built company, and we’ve learned a lot in over 80 years of helping our customers Forge Forward and helping their business grow.

When R.Q. McEniry purchased Standard Welders Supply in 1950, the vision of a full-service, family-built gas supplier was born. In 1996, Standard Welders merged with Mid-South Oxygen to form nexAir. Two generations later, the company still upholds McEniry’s original values and ideals.

Now, with chemists, engineers, welding analysts, cryogenic technicians, and medical equipment specialists, the knowledge base and expertise at nexAir is unprecedented. But we’re not content with what we already know. We measure and track all complaints and issues, take corrective action, and share our results directly with our customers. All nexAir gases are produced at our FDA-compliant, ISO 17025-certified plants. They operate 24/7 to produce precise, consistent, and reliable gases so you can focus on what’s truly important.

We work diligently every day to ensure we’re providing the best service possible. And we’re confident that when you work with nexAir, your business will be better for it.
