Air Compressor For Laser Cutting

When choosing compressor you need to consider if it can constantly provide desired pressure and volume of air. Small airbrush compressors little compressors boast amazing pressure figures but actually poor flow rates adequate limited to airbrush pistols. Actually if small compressor can push enough air it’ll likely overheat in short while.

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

it had been rated for volume 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 Air Compressor For Laser Cutting operate on a regular basis 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 concern with overheating since compressor engine isn’t on constantly. Using reserve air in tank we can also push up to 3.5bar (50psi) for short jobs.

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