Nitrogen Generator
Carbon Molecular Sieves
Collaboration Case
Laser cutting nitrogen generators primarily utilise the principle of pressure swing adsorption (PSA) to separate oxygen and nitrogen from the air. Pressure swing adsorption (PSA) is an advanced gas separation technology that employs high-quality imported carbon molecular sieves (CMS) as the adsorbent, utilising the PSA principle at ambient temperature to separate air and produce high-purity nitrogen. During the laser cutting process, the primary function of nitrogen is to protect the metal cut surface and enhance the quality of the cut by preventing oxidation. As an inert gas, nitrogen displaces the oxygen surrounding the cutting area, thereby preventing the oxidation of the metal material and ensuring that the cut edges remain clean, free from discolouration or rust. This is crucial for high-end metal cutting, particularly for materials such as 304 stainless steel and 6061 aluminium alloy.

Rigorous application condition design
Under the following operating conditions, the nitrogen production equipment operates stably and continuously at full load< Environmental temperature:- 20 ℃~+50 ℃
Environmental humidity: ≤ 95%
Atmospheric pressure: 80kPa~106kPa
Note: Special design is allowed if it is not within the above operating range
Easy installation and maintenance
Compact and reasonable modern industrial design, optimized shape, fine craftsmanship, compared with other nitrogen production equipment, it has high reliability, long service life, small installation area, and easy installation and maintenance.
1. Low energy consumption: when operating at full capacity to produce nitrogen, the unit’s total energy consumption is less than 39 kWh per hour;
2. Stable flow rate and controllable purity. The gas flow is consistent, and the nitrogen reaches equilibrium pressure after being stored in the air receiver;
3. Comprehensive coverage of common sheet metal cutting requirements, with up to 7 operating modes;
Carbon steel thick plate mode, carbon steel thin plate mode, aluminium alloy thick plate mode, aluminium alloy thin plate mode (burr-free cutting process), stainless steel thick plate mode, stainless steel thin plate mode; different operating modes can be selected according to the cutting requirements of various materials to achieve different cutting results;
4. Deoxidation, deburring and slag removal;
Effectively resolves issues such as slag formation during air cutting of stainless steel and carbon steel, as well as pipeline contamination, whilst addressing problems such as cross-sectional oxidation and low efficiency encountered when cutting thin and medium-thickness carbon steel using oxygen cutting;
5. High overall operational safety;
Utilises a time-delay solenoid valve to protect the nitrogen generator from the impact of the air (gas source), effectively regulating the nitrogen generation efficiency of the nitrogen generator;
