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

Why and How
Laser cuts by high temperature, very high warmth focused in tight beam. Side products of high heat are smoke and fire, both are not welcomed addition, smoke https://www.ever-power.net/?s=laser+cutting+air+compressor&post_type=product disperses laser beam reducint it’s efficienty and fire causes charring of material / edges and may even escape control leading to serious emergency.

Fire needs surroundings to burn nonetheless it will also die in the event that you blow too hard, think of a candle in the wind. This is essentialy what air assist is normally for: compressed air is extruded straight at the laser mind in a very tight stream and is directed at where laser touches material.

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

To attain required pressure compressor must push certain volume of air through surroundings assist opening, precise volume depends upon size of the opening and desired pressure. High 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 need to consider if it can constantly provide desired pressure and level of air. Little airbrush compressors small compressors boast amazing pressure figures but actually poor flow rates adequate only for airbrush pistols. Also if small compressor would be able to push enough air it will likely overheat in short while.
