Air Compressor For Laser Cutting

When choosing compressor you have to consider if it can constantly provide desired pressure and level of air. Small airbrush compressors little compressors boast impressive pressure figures but really poor flow rates adequate limited to airbrush pistols. Also if small compressor would be able to 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 what specifications it has but stream of air was extremely weak. It is adequate if all you have to to accomplish 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 tank which may be filled to 58 PSI. It were able to give us continuous 1 bar (14 PSI) of pressure, nonetheless it had to run at all times and overheat badly within five minutes.

Third and current compressor we got was 6cfm rated belt driven device with 13 gallon container which is filled to ~Air Compressor For Laser Cutting 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 atmosphere in tank we are able to also drive up to 3.5bar (50psi) for brief 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.
