In recent years, laser cutting has become the leader in the cutting industry with its advantages of fast speed, good cutting effect, easy use and low maintenance cost. Laser cutting machines have relatively high requirements for compressed air sources. So how to choose an air compressor that provides compressed air sources?
First we can refer to the following table to make preliminary power and pressure selections:
| Laser cutting machine power | Matching air compressor | Recommended cutting thickness(carbon steel) |
| Within 6kw | 15kw 16bar | Within 6mm |
| Within 10kw | 22kw 16bar/15kw 20bar | About 8mm |
| 12-15kw | 22/30/37kw 20bar | 10-12mm |
NOTE:
If there are other gas equipment in the workshop, air compressor needs to choose bigger one.
The above is only a reference matching scheme. According to different brands of laser cutting machines and air compressors, there maybe differences in the specific power selection.
Multiple laser cutting machines can use the same air compressor to supply air, but the air supply volume must be calculated.
So what are the characteristics of each of our three models, and what are the model parameters?

What should you pay attention to when using an air compressor on a daily basis?
PRECAUTIONS FOR DAILY USE:
1. lf air compressor is used less, the oil and gas barrel needs to be drained regularly, otherwise air end will rust.
2. 4-IN-1 series (OPA series) air tank needs to be flushed with water about once every 8 hours. If automatic drain valve is installed, manual operation is not required.
SIMPLE POWER-ON STEPS:
1. Connect the power supply (after power-on, if it displays: phase sequence error, swap the positions of any two live wires, and then restart)
2. Turn on the air dryer 5 minutes in advance, and then start the air compressor;You can use the air compressor normally.
