Laser cutting air compressor

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

Why and How
Laser cuts by heat, very high heat focused in tight beam. Side items of high temperature 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 get out of control causing serious emergency.

Fire needs air flow to burn but it can also die if you blow too hard, think about a candle in the wind. That is essentialy what surroundings assist is normally for: compressed surroundings is extruded directly at the laser head in a very limited stream and is fond of where laser touches material.

Air Compressor For Tire Production Equipment pressure and volume of air
Pressure of air is key variable for air help efficienty, in our shop we found out that optimal value is between 2 and 3.5 bar (31-50psi).

To attain required pressure compressor must push certain level of air through air flow assist opening, exact volume depends on size of the opening and desired pressure. High quality laser cutter heads have small and finely tuned openings while cheaper chinese cutters just 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 level of air. Small airbrush compressors small compressors boast amazing pressure figures but really poor flow rates enough only for airbrush pistols. Actually if small compressor would be able to push enough air it’ll likely overheat in short while.
