Product Detail
PSA Nitrogen Generator for Laser Cutting
Bottled nitrogen is one of the highest recurring costs in fiber laser cutting of stainless steel and aluminum. The PSA Nitrogen Generator from Shandong Xinhong CNC eliminates that cost by producing 99.9% pure nitrogen on-site from compressed air. With output flow rates from 10 to 80 cubic meters per hour, it matches the assist gas demand of fiber laser cutting machines from 1000W to 12000W. Integrated membrane separation technology and dual filtration stages remove moisture and particulates, ensuring consistent cutting performance on stainless steel and aluminum. Typical payback period is 6-12 months compared to bottled nitrogen supply, after which the only running expense is compressed air consumption.

FAQ
How does PSA nitrogen generation work?
PSA (Pressure Swing Adsorption) uses carbon molecular sieves to separate nitrogen from oxygen in compressed air. At high pressure, the sieve adsorbs oxygen and lets nitrogen pass through. The system alternates between two sieve beds, producing a continuous nitrogen supply at 99.9% purity without consumables.
What size air compressor do I need?
The generator requires a compressed air supply at 0.6-0.8 MPa inlet pressure. The required compressor capacity depends on your nitrogen flow rate setting. Contact us with your cutting machine power level and typical daily usage, and we'll specify the appropriate compressor size.
How long until the system pays for itself?
Typical payback period is 6-12 months compared to bottled nitrogen costs, depending on your nitrogen consumption volume and local bottled gas pricing. After payback, running expenses are limited to compressed air electricity consumption and monthly filter cartridge replacement.
Is 99.9% purity sufficient for laser cutting?
Yes. 99.9% nitrogen purity is the standard for fiber laser cutting of stainless steel and aluminum, producing bright, oxide-free cut edges. For applications requiring ultra-high purity (99.999%), higher-tier PSA configurations are available on request.
What maintenance does the system require?
Monthly filter cartridge replacement is the primary maintenance task. The PSA sieve beds have a long service life (typically 5+ years) under normal operating conditions. No daily maintenance is required - the system operates automatically once configured.
