Air Compressor For Laser Cutting

When choosing compressor you need to consider if it will be able to Air Compressor For Laser Cutting constantly provide desired pressure and level of air. Small airbrush compressors small compressors boast impressive pressure figures but really poor flow rates adequate only for airbrush pistols. Also if small compressor would be able to push enough air it’ll likely overheat in short while.

Our laser cutter came with small membrane pump (Smallest upon the picture), I do not know what specifications it has but blast of air was extremely weak. It is sufficient if all you have to to do is engrave, although even then we got considerable 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 managed to give us continuous 1 bar (14 PSI) of pressure, but it had to operate at all times and overheat badly within five minutes.

Third and current compressor we got was 6cfm rated belt driven unit with 13 gallon container which is filled to ~100psi. With this unit we can run at continuous ~2bar (31psi) without concern with overheating since compressor engine isn’t on continuously. Using reserve surroundings in tank we can 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.
