Laser cutting air compressor

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

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

Fire needs atmosphere to burn but it will also die in the event that you blow too hard, think about a candle in the wind. This is essentialy what atmosphere assist is for: compressed atmosphere is extruded directly at the laser head in a very restricted stream and is directed at where laser touches material.

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

To accomplish required pressure compressor must push certain volume of air through air flow assist opening, specific volume depends upon size of the starting and desired pressure. High quality laser cutter heads have https://www.ever-power.net/?s=laser+cutting+air+compressor&post_type=product little and finely tuned openings while cheaper chinese cutters simply blow in general direction via huge holes.

Proper compressor
When choosing compressor you should consider if it will be able to constantly provide desired pressure and level of air. Little airbrush compressors small compressors boast amazing pressure figures but really poor flow rates sufficient only for airbrush pistols. Actually if small compressor would be able to push enough air it will likely overheat in couple of minutes.
