1、10W Optical Power: The laser engraving module has an output power of 40W and 10W optical power, compressed spot technology, which is a fixed focusing module that can make the engraving process more accurate and efficient.10W optical power laser head (12V, GND, PWM) can engrave and cut metal, wood, MDF, acrylic, foam, resin, nylon, carbon fiber, PCB, etc. 2、Air Assist: 0.08x0.08mm compression point can cut 3mm acrylic sheet and 8mm sheet at one time. Equipped with strong air assist (including air assist nozzle and pump), it can greatly speed up the heat dissipation and blow away the smoke generated during the engraving or cutting process. 3、Good Compatibility: The engraving laser module with air assist is compatible with most laser engraving and cutting machines, CNC engraving machines, 3D printers and so on. It is an ideal accessory for engraving and cutting. 4、Cleaner Operating Surfaces: The machine with air assist will not distort or darken the engraved object due to burning heat caused by the high temperatures generated by the laser. Therefore, the engraving and table can be kept clean and good. 5、Low Noise: Powerful 10W laser cutting capacity and powerful air assisted device make the engraving machine work easier. The amplitude of the air assisted vibration is very small and will not affect the focusing of the laser. It has very good noise reduction ability.
