Air Compressor For Laser Cutting

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

Our laser cutter came with little membrane pump (Smallest upon the picture), I really do not know very well what specifications it has but stream of air was very weak. It is adequate if all you want to do is engrave, although even then we got considerable 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, nonetheless it had to run constantly and overheat badly within five 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 fear of overheating since compressor engine isn’t on constantly. Using reserve air in tank we are able to also push 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.
