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

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

it had been rated for volume of ~2.4cfm and had a 1 gallon container which can be filled to 58 PSI. It were able to give us constant 1 bar (14 PSI) of pressure, nonetheless it had to operate constantly 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 are able to run at constant ~2bar (31psi) without concern with overheating since compressor engine isn’t on all the time. Using reserve air in tank we can also press up to 3.5bar (50psi) for brief jobs.

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