All Laser Cutters want two additional devices which move atmosphere: blower which removes atmosphere / extracts smoke from machine and air compressor as a source for compressed air flow for so called atmosphere assist.
Why and How
Laser cuts by heat, very high heat focused in tight beam. Side products of high heat are smoke and fire, both aren’t welcomed addition, smoke disperses laser reducint it’s efficienty and fire causes charring of materials / edges and may even escape control leading to serious emergency.
Fire needs air to burn but it can also die if you blow too hard, think of a candle in the wind. This is essentialy what air flow assist is certainly for: compressed surroundings is extruded directly at the laser head in a very tight stream and is fond of where laser Air Compressor For Tire Production Equipment touches material.
Pressure and volume of air
Pressure of atmosphere is essential variable for air help efficienty, in our shop we discovered that optimal value is between 2 and 3.5 bar (31-50psi).
To accomplish required pressure compressor must push certain level of air through surroundings assist opening, specific volume depends upon size of the opening and desired pressure. Top quality laser cutter heads have small and finely tuned openings while cheaper chinese cutters just blow generally direction via huge holes.
When choosing compressor you have to consider if it will be able to constantly provide desired pressure and volume of air. Small airbrush compressors small compressors boast impressive pressure figures but actually poor flow rates sufficient only for airbrush pistols. Even if small compressor would be able to push enough air it will likely overheat in short while.
