All Laser Cutters want two additional products which move air: blower which removes air flow / extracts smoke from machine and atmosphere compressor as a source for compressed air for so called air flow assist.

Why and How
Laser cuts by high temperature, very high high temperature focused in tight beam. Side items of high temperature are smoke and fire, both aren’t welcomed addition, smoke disperses laser beam reducint it’s efficienty and fire causes charring of materials / edges and will even get out of control leading to serious emergency.

Fire needs surroundings to burn but it will also die if you blow too hard, think of a candle in the wind. That is essentialy what surroundings assist is for: compressed air is extruded directly at the laser mind in a very limited stream and is directed at the place where laser touches material.

Pressure and level of air
Pressure of air flow is key variable for air support efficienty, in our shop we found out that optimal worth is between 2 and 3.5 bar (31-50psi).

To attain required pressure compressor must push certain level of air through air flow assist opening, precise volume depends upon size of the opening and desired pressure. High quality laser cutter heads have little and finely tuned openings while cheaper chinese cutters simply blow generally direction via huge holes.

Proper compressor
When choosing compressor you should consider if it can constantly provide desired pressure and level of air. Small airbrush compressors little compressors boast impressive pressure figures but actually poor flow rates enough only for airbrush pistols. Even if small compressor can push enough air it’ll likely overheat in short while.
