Laser cutting air compressor

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

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

Fire needs air to burn nonetheless it can also die in the event that you blow too hard, think about a candle in the wind. That is essentialy what atmosphere assist is definitely for: compressed atmosphere is extruded directly at the laser mind in a very limited stream and is fond of where laser touches material.

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

To accomplish required pressure compressor must push certain level of air through air flow assist opening, precise volume depends upon size of the starting and desired pressure. Top quality laser cutter heads have small and finely tuned openings while cheaper chinese cutters simply blow generally direction via large holes.

Proper compressor
When choosing compressor you have to consider if it will be able to constantly provide desired pressure and volume of air. Little airbrush compressors small compressors boast impressive pressure figures but really poor flow rates enough only for airbrush pistols. Even if small compressor can push enough air it will likely overheat in couple of minutes.
