Laser Cutting Auxiliary · PSA Nitrogen Generation

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.

Buyer Pain Points & Solutions

Bottled nitrogen cost and logistics: Bottled N2 requires regular deliveries, storage space, cylinder handling, and rental fees. The PSA generator produces nitrogen on-demand from compressed air - no deliveries, no cylinders, no rental fees. Running cost drops to electricity for the air compressor you already have.

Flow rate mismatch with cutting demand: Bottle regulators can't always keep up with peak assist gas demand on thick stainless steel. The generator's 10-80 m³/h adjustable output matches cutting machine demand in real time, preventing pressure drops that degrade cut quality.

Moisture and particulate contamination: Impure assist gas causes oxidation and pitting on cut edges. Dual filtration stages and membrane separation remove moisture and particulates before the nitrogen reaches the cutting head, ensuring clean, oxide-free edges on stainless and aluminum.

Core Advantages

On-site 99.9% nitrogen production - PSA (Pressure Swing Adsorption) technology extracts nitrogen from compressed air, delivering 99.9% purity continuously without cylinder refills or deliveries.

Adjustable 10-80 m³/h flow rate - Output matches cutting machine demand across power levels from 1000W to 12000W. Automatic pressure regulation maintains consistent flow during peak cutting cycles.

Dual filtration + membrane separation - Two-stage filtration removes moisture and particulates; membrane separation ensures purity consistency. The system delivers clean, dry nitrogen that won't contaminate cut edges.

6-12 month ROI vs. bottled nitrogen - After the initial payback period, running expenses are limited to compressed air consumption. Monthly maintenance requires only filter cartridge replacement.

Compact, low-noise design - The unit operates below 75dB and has a compact footprint suitable for shop floor integration alongside the cutting machine - no dedicated mechanical room required.

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.
