Laser cutting air compressor

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

Why and How
Laser cuts by warmth, very high high temperature 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 will even escape control causing serious emergency.

Fire needs air flow to burn nonetheless it will also die if you blow too hard, think of a candle in the wind. This is essentialy what surroundings assist is certainly for: compressed surroundings is extruded directly at the laser mind in a very limited stream and is fond of the place where laser touches material.

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

To accomplish required pressure compressor needs to push certain level of air through atmosphere assist opening, specific volume depends on size of the starting and desired pressure. Top quality laser beam cutter heads have small and finely tuned openings while cheaper chinese cutters simply blow in general direction via large holes.

Proper compressor
When choosing compressor you should consider if it can constantly provide desired pressure and level of air. Little airbrush compressors little compressors boast impressive pressure figures but actually poor flow rates sufficient limited to airbrush pistols. Actually if small compressor can push enough air it’ll likely overheat in short while.
