When choosing compressor you should consider if it can constantly provide Air Compressor For Laser Cutting china 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 would be able to push enough air it will likely overheat in short while.
Our laser cutter was included with small membrane pump (Smallest upon the picture), I really do not know what specifications it has but blast of air was very weak. It is adequate if all you have to 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 container which can be filled to 58 PSI. It were able to give us continuous 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 is not on constantly. Using reserve air in tank we are able to also drive 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.
