All Laser Cutters want two additional products which move atmosphere: blower which removes air / extracts smoke from machine and air flow compressor as a source for compressed Air Compressor For Tire Production Equipment surroundings for so called atmosphere assist.
Why and How
Laser cuts by warmth, very high temperature focused in tight beam. Side products 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 can even get out of control causing serious emergency.
Fire needs surroundings to burn nonetheless it can also die in the event that you blow too hard, think of a candle in the wind. That is essentialy what air flow assist is normally for: compressed atmosphere is extruded directly at the laser head in a very restricted stream and is directed at the place where laser touches material.
Pressure and level of air
Pressure of atmosphere is key variable for air aid efficienty, in our shop we found out that optimal worth is between 2 and 3.5 bar (31-50psi).
To achieve required pressure compressor needs to push certain volume of air through surroundings 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 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. Little airbrush compressors small compressors boast amazing pressure figures but really poor flow rates sufficient limited to airbrush pistols. Actually if small compressor can push enough air it’ll likely overheat in short while.
