Air Compressor For Laser Cutting

When choosing compressor you need to consider if it can constantly provide desired pressure and level of air. Small airbrush compressors little compressors boast impressive pressure figures but actually poor flow rates enough limited to airbrush pistols. Also if small compressor can push enough air it'll likely overheat in couple of minutes.

Our laser cutter was included with small 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 enough if all you want to accomplish is engrave, although actually then we got substantial smoke traces around engraved Air Compressor For Laser Cutting picture.

it had been rated for level of ~2.4cfm and had a 1 gallon tank which may be filled to 58 PSI. It were able to give us constant 1 bar (14 PSI) of pressure, but it had to 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 can run at continuous ~2bar (31psi) without concern with overheating since compressor engine isn't on continuously. Using reserve atmosphere in tank we are able to also push up to 3.5bar (50psi) for brief 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.
