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

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

it had been rated for level of ~2.4cfm and had a 1 gallon tank which can be filled to 58 PSI. It managed to give us continuous 1 bar (14 PSI) of pressure, but it had to run at all times and overheat badly within five minutes.

Third and current compressor we got was 6cfm rated belt driven device with 13 gallon tank which is filled to ~100psi. With this unit we are able to run at constant ~2bar (31psi) without fear of overheating since compressor engine isn’t on on a regular basis. Using reserve air flow in tank we are able to also press up to 3.5bar (50psi) for short jobs.

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