Features: [Appropriate] The OAP1.0 air booster pump is applicable with Ortur laser master 3 and LU2-4 LF laser module. [Powerful airflow] Large and stable wind, with a constant output of 50 l or min, effectively removes smoke and ensures the stability of laser energy. [Clean surface and smooth edge] Using air pump, strong air flow quickly reduces the temperature of the material surface being cut, preventing distortion and discoloration caused by high temperatures, ensuring smooth lines, complete patterns and clean material surfaces. [Keep noise and vibration low] ORTUR air assist kit has the advantages of low noise and vibration. Vibrations generated by the air-assisted device during the laser cutting process will not affect the positioning of the laser head, ensuring continuous cutting of lines and complete patterns [Protect Laser Head] The ORTUR air assist kit features a stable air outlet system that blows out acceptable debris and smoke generated during laser head operation, protecting the laser head lens from contamination and extending the life of the laser head.
