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

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

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

Pressure of atmosphere is key adjustable for air support efficienty, in our shop we discovered that optimal worth is Laser Cutting Air Compressor between 2 and 3.5 bar (31-50psi).

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