If you're using nitrogen bottles for your laser cutting machine, you already know how quickly the costs add up. A typical nitrogen bottle may only provide around 40 minutes of cutting — meaning you're constantly replacing bottles, interrupting production, and watching your profits disappear. What if you could eliminate that ongoing cost completely? With Isobex Laser-Configured Air Compressors, you can.
Using nitrogen for laser cutting might seem like the standard solution — but it's expensive, inefficient, and inconvenient. The reality:
You're not just buying nitrogen — you're committing to a never-ending cost.
Isobex Lasers offers specially formulated and configured compressors designed specifically for laser cutting applications. Our systems are:
This means better performance, lower costs, and less downtime.
Many laser users are spending hundreds — sometimes thousands — every month on nitrogen. When you switch to an Isobex compressor:
For many customers, the system pays for itself in under 12 months — sometimes much sooner. After that? It's pure savings.
One of the biggest frustrations with nitrogen bottles is running out halfway through a job. With an Isobex compressor:
Just reliable performance when you need it.
Nitrogen prices go up. Delivery charges increase. Supply delays happen. With an Isobex compressor:
This is about future-proofing your business.
If your nitrogen bottle lasts around 40 minutes, the costs can add up faster than you think:
Now multiply that by your cost per bottle… Even at modest prices, you're likely spending hundreds — sometimes thousands — every month on nitrogen alone. And that cost never stops.

Ask an engineer →Yes — compressed air is a popular and cost-effective alternative to nitrogen for many laser cutting applications. Isobex compressors deliver clean, dry air suitable for many cutting requirements.
Compressed air works well across many common fabrication materials, particularly mild steel. Some materials and finishes still cut best on nitrogen, so we review your specific jobs and advise where air is suitable.
For many applications, yes. On certain materials and thicknesses nitrogen still gives the cleanest edge, which is why we assess your specific cutting before recommending a switch.
Our compressors are engineered to integrate with industrial laser cutting machines. Tell us your make, model and air requirements and we'll match the right system.
It depends on your nitrogen usage and working hours. Many customers see the system pay for itself in under 12 months — share your usage and we'll estimate your savings and ROI.
Yes. Our systems are designed for clean, dry air output with the drying and filtration needed to protect your optics and keep cut quality consistent.
No. We handle delivery, positioning and commissioning in the UK, and validate capacity, pressure and air quality before you go into production.
Yes. Support continues well beyond installation, with parts availability and direct access to our engineers.
For many customers, payback comes in under 12 months — sometimes much sooner. After that, you're simply saving every month.
