When choosing compressor you need to consider if it can Air Compressor For Laser Cutting china constantly provide desired pressure and level of air. Small airbrush compressors little compressors boast amazing pressure figures but actually poor flow rates sufficient limited to airbrush pistols. Actually if small compressor would be able to push enough air it’ll likely overheat in short while.

Our laser cutter came with little membrane pump (Smallest upon the picture), I do not know what specifications it has but blast of air was extremely weak. It is enough if all you have to to do is engrave, although actually then we got considerable smoke traces around engraved picture.

it was rated for level of ~2.4cfm and had a 1 gallon tank which may be filled to 58 PSI. It were able to give us constant 1 bar (14 PSI) of pressure, nonetheless it had to operate on a regular basis and overheat badly within 5 minutes.

Third and current compressor we got was 6cfm rated belt driven unit with 13 gallon container which is filled to ~100psi. With this unit we can run at constant ~2bar (31psi) without concern with overheating since compressor engine is not on on a regular basis. Using reserve air in tank we can also drive up to 3.5bar (50psi) for short jobs.

The best setup for me would be compressor rated to >6cfm, huge 70+ gallons tank rated to 10bar (140psi) and software air control via solenoid valve.
