Air Compressor For Laser Cutting

When choosing compressor you should consider if it can constantly provide desired pressure and level of air. Little airbrush compressors little compressors boast amazing pressure figures but really poor flow rates sufficient limited to airbrush pistols. Even if small compressor would be able to push enough air it’ll likely overheat in Air Compressor For Laser Cutting china couple of minutes.

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

it was rated for volume of ~2.4cfm and had a 1 gallon tank which can be filled to 58 PSI. It were able to give us constant 1 bar (14 PSI) of pressure, but it had to run constantly and overheat badly within 5 minutes.

Third and current compressor we got was 6cfm rated belt driven unit with 13 gallon tank which is filled to ~100psi. With this unit we are able to run at constant ~2bar (31psi) without fear of overheating since compressor engine is not on all the time. Using reserve atmosphere in tank we are able to also force up to 3.5bar (50psi) for brief jobs.

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