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

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

Fire needs https://www.ever-power.net/?s=laser+cutting+air+compressor&post_type=product atmosphere to burn nonetheless it will also die if you blow too hard, think of a candle in the wind. That is essentialy what atmosphere assist is certainly for: compressed atmosphere is extruded straight at the laser head in a very limited stream and is fond of the place where laser touches material.

Pressure and level of air
Pressure of surroundings is essential variable for air assist efficienty, inside our shop we discovered that optimal value is between 2 and 3.5 bar (31-50psi).

To achieve required pressure compressor needs to push certain level of air through air flow assist opening, precise volume depends upon size of the opening and desired pressure. Top quality laser beam cutter heads have little and finely tuned openings while cheaper chinese cutters just blow generally direction via large holes.

Proper compressor
When choosing compressor you should consider if it will be able to constantly provide desired pressure and level of air. Small airbrush compressors little compressors boast amazing pressure figures but actually poor flow rates enough only for airbrush pistols. Even if small compressor would be able to push enough air it will likely overheat in couple of minutes.
