PR-N PSA Nitrogen Generator
The PR-N is a high-efficiency PSA (Pressure Swing Adsorption) nitrogen generator specifically designed for laser welding and cutting. By extracting nitrogen directly from the air, it eliminates the need for expensive, heavy gas cylinders. It ensures a stable supply of high-purity shielding gas, keeping your welds bright and your operating costs extremely low.
Key Engineering Advantages
- Continuous On-Site Supply: No more waiting for gas cylinder deliveries or worrying about running out of gas mid-weld.
- High-Purity Shielding: Produces 99.99% ~ 99.999% pure nitrogen, ensuring bright, oxidation-free weld seams with less grinding.
- Massive Cost Savings: You only pay for the electricity to run the machine and compressor, cutting gas costs by up to 80%.
- Compact & Mobile: Vertical cabinet design with heavy-duty casters makes it easy to move around the workshop.
- Fully Automatic: Real-time pressure gauge display with automatic pressure-stabilized gas supply. No manual adjustment needed.
- Global Ready: Supports OEM, neutral packing, and CE kits for overseas laser equipment matching buyers.
Why Buy a Nitrogen Generator?
💰 Stop Renting Cylinders
Buying or renting nitrogen cylinders is expensive and logistically annoying. The PR-N pays for itself in just a few months of saved gas costs.
💨 Never Run Out of Gas
As long as you have compressed air, you have nitrogen. No downtime waiting for the gas truck to arrive. Keep your welders running 24/7.
✨ Perfect for Laser Welding
Even a tiny amount of oxygen in the shielding gas will cause stainless steel welds to turn black. Our high-purity N2 guarantees a beautiful, silver weld.

Frequently Asked Questions
How much can I save by using a nitrogen generator?
You only pay for the electricity to run the compressor. On average, factories save 50% to 80% on their shielding gas costs compared to buying nitrogen cylinders.
What purity of nitrogen does it produce?
The PR-N series produces nitrogen with a purity ranging from 99.99% to 99.999%, which is ideal for preventing oxidation in laser welding and cutting.
Does it require an air compressor?
Yes, it requires a clean compressed air supply (0.6-0.8 MPa). If you don't have one, we can also supply a matching high-quality air compressor.
