Air Compressor For Laser Cutting

When choosing compressor you have to consider if it will be able to constantly provide desired Air Compressor For Laser Cutting pressure and volume of air. Small airbrush compressors little compressors boast amazing pressure figures but really poor flow rates sufficient only for airbrush pistols. Also if small compressor can push enough air it will likely overheat in couple of minutes.

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

it had been rated for level of ~2.4cfm and had a 1 gallon container which may be filled to 58 PSI. It managed to give us constant 1 bar (14 PSI) of pressure, but it had to run constantly 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 can run at constant ~2bar (31psi) without fear of overheating since compressor engine is not on all the time. Using reserve air flow in tank we can also force up to 3.5bar (50psi) for short jobs.

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