Blow away hot smoke when cutting materials, reduce the temperature, and cut more cleanly and smooth. The xTool air assist device blows away acceptable debris and smoke generated by the laser head operation, protecting the laser head lens from contamination and extending the life of the laser head. It uses air to quickly reduce the temperature of the cut material surface, preventing distortion and discoloration due to high temperatures, ensuring smooth lines, complete patterns, and clean material surfaces. Large and stable wind, with a steady output power of 30L/min, effectively removes smoke and ensures laser energy stability. The noise of the air-assist unit when working is 40 decibels, which is lower than the working sound of the fan. The air assist unit can provide you with a quiet laser engraving environment.
