All Laser Cutters need two additional products which move surroundings: blower which removes air / extracts smoke from machine and atmosphere compressor as a source for compressed air flow for so called air assist.
Laser cuts by high Laser Cutting Air Compressor temperature, very high heat focused in tight beam. Side products of high heat are smoke and fire, both are not 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 atmosphere to burn nonetheless it will also die if you blow too hard, think about a candle in the wind. This is essentialy what atmosphere assist is definitely for: compressed air is extruded straight at the laser mind in a very tight stream and is fond of where laser touches material.
Pressure of air is key variable for air support efficienty, in our shop we discovered that optimal worth is between 2 and 3.5 bar (31-50psi).
To achieve required pressure compressor must push certain level of air through air assist opening, specific 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 just blow generally direction via large holes.
