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

Why and How
Laser cuts by heat, very high warmth focused in tight beam. Side products of high heat are smoke and fire, both aren’t welcomed addition, smoke disperses laser reducint it’s efficienty and fire causes charring of materials / edges and can even get out of control causing serious emergency.

Fire needs air to burn but it can also die if you blow too hard, think about a candle in the wind. That is essentialy what atmosphere assist is for: compressed surroundings is extruded directly at the laser head in a very tight https://www.ssj-group.com/?s=laser+cutting+air+compressor&post_type=product stream and is directed at the place where laser touches material.

Pressure and volume of air
Pressure of air is essential variable for air help efficienty, in 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 volume of air through surroundings assist opening, specific volume depends on size of the opening and desired pressure. High quality laser beam cutter heads have little and 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 can constantly provide desired pressure and level of air. Little airbrush compressors little 5d4281c46d5b1compressors boast amazing pressure figures but actually poor flow rates sufficient limited to airbrush pistols. Also if small compressor would be able to push enough air it will likely overheat in couple of minutes.
