1、Cut Faster & Deeper: The air assist is equipped with adjustable airflow from 22L/min, which can blow away smoke and debris generated by the laser engraver's work, help the engraver to cut faster and deeper, improve laser efficiency and save your time. 2、Clean Surface & Smooth Edge: The air assist device can use air to quickly and effectively reduce the surface temperature of the object during the engraving and cutting, preventing deformation and discoloration caused by high temperature, ensuring smooth lines and complete patterns, and the edges will be cleaner and clearer. 3、Protect Laser Lens: The high velocity airflow stops smoke and particles from flowing upward into the laser module, protecting the laser lens and thus extending the life of the laser module. 4、Low Noise & Vibration: Air assist set provides a quiet working environment by significantly reducing noise and vibration without compromising laser cutting accuracy and speed. 5、Easy to Install and Use: This portable and lightweight Laser Air Assist Engraver is simple to set up—just connect the air hose and power adapter. It takes up minimal space and portable.
