Air compression
Screw compressor and air buffer capacity are checked against flow and duty cycle.
ON-SITE NITROGEN SUPPLY
PSA nitrogen generation configured around your cutting demand
A complete or modular nitrogen supply for laser cutting plants that want to generate nitrogen on site and retain the equipment that already works.
Project-configured · Pure-nitrogen or mixed-gas workflows · No direct online purchase
ROLE IN THE GAS SYSTEM
An optional upstream nitrogen source—not a mandatory part of every project
Use the PSA system for pure nitrogen cutting, or as the upstream nitrogen source for one selected N₂/O₂ mixer. Plants with a suitable liquid, bulk or cylinder nitrogen supply can use that source instead.

SYSTEM BOUNDARY
Specify the full line, then decide which modules are actually supplied
The engineering review starts with the complete gas path. The supply scope is then reduced or expanded according to the customer’s existing compressor, air treatment, tanks and booster.
Air purification
Drying and staged filtration protect the adsorption process and downstream gas quality.
PSA generation
Twin-tower adsorption separates nitrogen from compressed air for the required process demand.
Buffer and storage
Process and storage vessels stabilize supply around the selected operating profile.
Pressure boosting
A nitrogen booster raises pressure when the cutting process or downstream mixer requires it.
REFERENCE CASE · SINGLE LASER
On-site nitrogen concept for one 6 kW laser cutter
This documented layout is presented as a project reference—not as a fixed package for every 6 kW machine. The page shows only the values needed for an initial fit discussion.
- Laser load
- 6 kW
- Nitrogen flow
- 40 Nm³/h
- Reference purity
- 99.99%
- Boosted pressure
- 2.0 MPa
CONFIGURATION INPUTS
What we need before selecting the system
Send operating conditions rather than choosing by flow alone. Final sizing depends on actual duty cycle, gas consumption, ambient conditions and the equipment retained on site.
- Target nitrogen flow, purity and outlet pressure
- Laser quantity, power, material range and daily operating hours
- Existing compressor, dryer, filters, tanks and booster
- Available installation space and utility conditions
- Pure-nitrogen cutting or mixed-gas operating plan
PSA SELECTION QUESTIONS
Questions that change the system scope
Do we need to buy the full PSA system?
Not necessarily. Suitable compressors, air treatment equipment, tanks or boosters can remain in the project after their capacity and condition are reviewed.
Can the PSA system feed pure nitrogen cutting directly?
Yes, when the generated flow, purity and pressure match the cutting requirement. The same nitrogen source can also feed one selected mixed-gas controller when N₂/O₂ mixing is required.
Are 40 and 75 Nm³/h the only available capacities?
They are the two reference configurations supported by the current documents. Other requirements must be assessed rather than inferred from an unverified model range.
