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

Why and How
Laser cuts by heat, very high temperature focused in tight beam. Side items of high temperature are smoke and fire, both are not welcomed addition, smoke disperses laser beam reducint it’s efficienty and fire causes Air Compressor For Tire Production Equipment charring of material / edges and may even get out of control causing serious emergency.

Fire needs atmosphere to burn but it can also die in the event that you blow too hard, think of a candle in the wind. That is essentialy what atmosphere assist is definitely for: compressed surroundings is extruded directly at the laser head in a very tight stream and is directed at where laser touches material.

Pressure and volume of air
Pressure of surroundings is essential variable for air support efficienty, in our shop we found out that optimal value is between 2 and 3.5 bar (31-50psi).

To attain required pressure compressor must push certain volume of air through surroundings assist opening, precise volume depends on size of the starting and desired pressure. Top quality laser cutter heads have little and finely tuned openings while cheaper chinese cutters simply blow in general direction via large holes.

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