Product advantages

1. High stability

Imported screw main machine ensures high efficiency, high stability, smoother cutting and cutting surface.

2. High-efficiency motor

Dustproof and waterproof motor, the protection level reaches IP54, which meets the environment with more dust and smoke, dust and moisture in the air are not easy to enter the motor, and maintain long-term trouble-free operation.

3. One-piece does not need to be installed

Easy to use and transport, easy to operate.

4. Multi-stage high efficiency filter

The multi-stage high-efficiency US original Donaldson filter, with a filtration accuracy of 2um, ensures that the air inhaled by the host is pure and free of impurities, and ensures the host's trouble-free operation.

5. Low noise

Shock-absorbing frame, thickened sheet metal thickness, and thickened shock-absorbing pads to minimize noise.

6. Thermostatic control

Minimize the water content inside the system to ensure long life and high efficiency of the air compressor.

7. 500L large capacity storage tank

500 liter bulk tank for air storage and buffering. The air supply is more stable, preventing frequent loading and unloading of the compressor. The precipitation of compressed air in the tank is also more conducive to sewage and water removal.

DuriAuxiliary gas for Fiber Laser Cutting, did you get the right one?

The schematic diagram of laser cutting is shown in the following.



During the process, auxiliary gas is necessary to blow off the slag/dross in the kerf and cool down the cutting surface, also it protects lens and nozzle of laser. Basically there are 3 kinds of gas: Oxygen, Nitrogen and Air, any of them affects directly to the cutting performance, speed, thickness etc. So we really need to think better before action.

1.OxygenOxygen is commonly used to cut thick carbon steel because the chemical reaction between iron element and oxygen helps the metal absorb heat and promotes it melt, which can greatly improve the cutting efficiency.

However, oxygen will cause a marked oxide film on the cut surface and it will have a quenching effect around, increases the hardness which impact on subsequent processing. It also turns kerf to black or dark yellow.



2. Nitrogen
Nitrogen will form around the molten metal as protective atmosphere while it's assisting the cut, prevent oxidation of the material, avoid the formation of oxide film. However, the cutting speed is not as fast as oxygen, and the nitrogen consumption of the nitrogen is large which means the cost will be higher.


3. Air
Air, as it's the most economic medium because it's much easier to obtain than oxygen and nitrogen, nobody can charge you for air!

Every one knows the air contains about 20% oxygen and about 78% nitrogen, so it can make up for both shortage and cutting speed is slower than oxygen but faster than nitrogen. Since the oxygen is involved, the kerf turns a little bit yellow. It's the most economic option for you as long as you are okay with the color change.

Generally compressed air can be used for cutting sheet-metal parts, aluminum sheet, nonmetal and galvanized sheet etc., air assist can certainly reduce the oxide film and absolutely save your cost, therefore, air assist is more and more equipped in fiber laser cut industry.

Compressed air can be obtained easily with an air compressor, but not any air compressor can be equipped for Fiber Laser Cutter as the Air itself is not clean, especially after compressing, there are plenty of water, oil and particles and any of them sprayed on the lens, the transmission of laser beam will be seriously affected and focus scattered, resulting bad cutting effect such as bottom burrs or rough kerf, even obsolescence.


Situation could be much worse if it is high-power fiber laser, even a tiny particle or a little spray will very possibly burn your entire lens cone.

In order to make the most economic (Air assist) way workable, ensure cutting quality and avoid any damage for your fiber laser, the compressed air must be pure and constant, 100% meet ISO 8573-1-2010 standard.
