When choosing compressor you have to consider if it will be able to constantly Air Compressor For Laser Cutting china provide desired pressure and volume of air. Little airbrush compressors small compressors boast amazing pressure figures but really poor flow rates adequate limited to airbrush pistols. Actually if small compressor can push enough air it will likely overheat in short while.
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 very weak. It is adequate if all you have to to do 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 were able to give us constant 1 bar (14 PSI) of pressure, but it had to run all the time 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 ~100psi. With this unit we are able to run at continuous ~2bar (31psi) without fear of overheating since compressor engine isn’t on on a regular basis. Using reserve air flow in tank we are able to also press 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.
