The air assist kit quickly reduces heat around the laser head and removes debris around the contact point. You will get better results with smooth lines, complete patterns, and clean material surfaces.

A laser air assist kit can effectively remove the smoke and dust generated in the process of laser engraving, prevent laser energy attenuation, and ensure the stability of laser energy, helping the engraver to cut faster and deeper.

LONGER air-assist set for laser cutter is designed for a laser engraver air assist system. This is portable and lightweight so that it can be taken to anywhere conveniently and will not take up much space.
