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 air flow for so called air flow assist.
Why and How
Laser cuts by temperature, very high warmth focused in tight beam. Side items of high heat are smoke and fire, both are not welcomed addition, smoke disperses laser reducint it’s efficienty and fire causes charring of material / edges and may even get out of control leading to serious emergency.
Fire needs Air Compressor For Tire Production Equipment atmosphere to burn nonetheless it will also die in the event that you blow too hard, think about a candle in the wind. This is essentialy what atmosphere assist can be for: compressed air is extruded straight at the laser head in a very restricted stream and is fond of the place where laser touches material.
Pressure and level of air
Pressure of atmosphere is essential variable for air help efficienty, in our shop we found out that optimal value is between 2 and 3.5 bar (31-50psi).
To accomplish required pressure compressor needs to push certain volume of air through atmosphere assist opening, specific volume depends upon size of the opening and desired pressure. High quality laser beam cutter heads have little and finely tuned openings while cheaper chinese cutters simply blow in general direction via huge holes.
When choosing compressor you should consider if it can constantly provide desired pressure and volume of air. Little airbrush compressors small compressors boast amazing pressure figures but actually poor flow rates adequate limited to airbrush pistols. Actually if small compressor can push enough air it will likely overheat in short while.
