When choosing compressor you have to consider if it will be able to Air Compressor For Laser Cutting china constantly provide desired pressure and volume of air. Small airbrush compressors little compressors boast impressive pressure figures but actually poor flow rates adequate 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 little membrane pump (Smallest upon the picture), I really do not know what specifications it has but stream of air was extremely weak. It is enough if all you want to accomplish is engrave, although also then we got substantial smoke traces around engraved picture.

it had been rated for volume of ~2.4cfm and had a 1 gallon tank which can be filled to 58 PSI. It managed to give us constant 1 bar (14 PSI) of pressure, but it had to run at all times and overheat badly within five 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 on a regular basis. Using reserve air flow in tank we are able to also force up to 3.5bar (50psi) for brief jobs.

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