Feature: 1. [Suitable] OAP1.0  Air Assist Pump is applicable with Ortur laser master 3 and LU2-4 LF laser module. 2. [Powerful Air Flow] Large and stable wind, with a steady output power of 50L/min, effectively removes smoke and ensures laser energy stability. 3. [Clean Surface \u0026 Smooth Edge] With the help of air pump powerful air flow 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. 4. [Keep Low Noise \u0026 Vibration] ORTUR air assist set has the advantages of low noise and vibration. The vibration generated by the air-assisted device, during the laser cutter working process will not affect the positioning of the laser head, ensuring continuous cutting of lines and complete patterns 5. [Protect Laser Head] ORTUR air assist set has a stable air output system that blows away the acceptable debris and smoke generated during the laser head\u0027s work, protecting the laser head\u0027s lens from contamination and extending the laser head\u0027s service life.
