Feature: 1. Clean in Cutting: A large and stable output airflow can blow away the smoke and dust generated during the laser cutting process. To prevent smoke and dust from attenuating laser energy, quickly reduce the surface temperature of cutting objects, prevent deformation and discoloration due to excessive combustion, and make cutting edges smoother and cleaner. And extend the life of the laser module lens. 2. Perfect Matching: Very suitable for S10 or other similar air assisted laser cutting machines, widely used in laser engraving machines, massage chairs, air cushion beds, fragrance expanders, air wave pressure therapy equipment, medical beauty equipment, sewage treatment, aquaculture, industrial and agricultural equipment, etc. 3. Better Stability: There are 4 rubber feet that can reduce noise and vibration during operation. High stability design ensures stable airflow output even after prolonged operation. 4. Adjustable Speed: The air pump has a speed control design, and you can adjust the flow rate from 0‑30L/Min through a rotary regulator, and adjust the airflow speed according to the needs of the laser engraving machine. 5. Quick to Install: Comes with a compact size and a light weight as well, the laser engraver air assist is very convenient to install within several minutes.
