Used Nitrogen & Oxygen Generators
Used nitrogen and oxygen generators, inspected and safety-tested, when trade-in units come in
Used generators, air compressors, and flow meters come into our factory on trade-in from time to time. When they do, we inspect, function-test, and safety-check each unit before we offer it. Availability changes, so tell us what you need and we will check what is on hand. If nothing used fits your process, a new build-to-order system typically pays back in 12 to 14 months.
When used makes sense
A used unit can bridge the budget when a new system is more than a startup or small shop can carry
Nitrogen generators, oxygen generators, air compressors, and flow meters are industrial capital equipment, and a new system is not always within budget for a startup or a small to medium business. A used unit can be the bridge that lets you package food under nitrogen, run a reflow solder line, or get a laser cutting operation started without paying new-equipment prices up front.
Used and refurbished equipment reaches us mainly through trade-ins, when a customer upgrades to a larger or newer system. Because supply depends on what has recently come back, availability changes and specific models are not always on hand. The fastest way to find out what is available right now is to tell us the gas type, purity, and flow you need, and let us check for you.
Gas Generation Solutions has been in business since 1979, serving customers across the United States, Mexico, and Canada. If used inventory does not match your application, we will price a new build-to-order system alongside it so you can compare. See nitrogen gas generators for sale for the new-equipment catalog, or nitrogen generator price tiers for a breakdown by size.
How it works
Three steps from your requirement to the right unit
Tell us what you need
Send the gas type, purity, and flow your application requires, plus the equipment you are feeding. That tells us whether a used unit on hand can actually do the job or whether you need a specific new size.
We check and inspect
We look at what has come in on recent trade-ins. Any used generator, compressor, or flow meter we offer has been inspected, function-tested, and safety-checked by our team. If a unit does not pass, we do not sell it.
Compare used and new
We quote what is available used and, when it helps, price a new build-to-order system next to it. You see both numbers and decide which one fits your budget and timeline.
If nothing used fits your application
Used inventory is limited, and the exact purity, flow, and pressure your process needs may not be on hand. A new build-to-order system is often closer in cost than expected once you factor in the payback: on-site nitrogen and oxygen generators typically pay for themselves in 12 to 14 months versus delivered gas and are designed to run for 20 years or more. Tell us what you need and we will price both.
Step 1: check what is available
Tell us what you need and we will check current used units
Send the gas type, purity, and flow your application requires. We will let you know what used equipment is on hand and whether it fits, with no obligation.
Step 2: price a new system too
Compare used against a new build-to-order quote
Flow rate, purity, output pressure, and what the gas feeds. Most quotes go out within 24 to 72 hours. Phone: 760-505-1300.
