Laser cutting air compressor

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

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

Fire needs air flow to burn but it can also die in the event that you blow too hard, think of a candle in the wind. This is essentialy what air assist is for: compressed atmosphere is extruded straight at the laser head in a very tight stream and is fond of where laser touches material.

Pressure and level of air
Pressure of air flow is essential variable for air support efficienty, inside 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 atmosphere assist opening, precise volume depends on size of the starting and desired pressure. High quality laser cutter heads have little and Air Compressor For Tire Production Equipment finely tuned openings while cheaper chinese cutters simply blow generally direction via huge holes.

Proper compressor
When choosing compressor you have to consider if it will be able to constantly provide desired pressure and volume of air. Small airbrush compressors little compressors boast amazing pressure figures but really poor flow rates adequate only for airbrush pistols. Also if small compressor can push enough air it’ll likely overheat in short while.
