Feature:1. SURFACE AND EDGE CLEAN: Air auxiliary pump use air to rapidly reduce the surface temperature of the cut material, avoid deformation and discoloration caused by high laser temperature, powerful airflow blows away the residue, to ensure the surface clean and cutting edge clean2. FASTER AND DEEPER CUTTING: The air pump is equipped with 80L or Min strong high speed airflow, which can blow away the smoke, residue and debris generated in the working process of the engraving machine, keep the laser focused on cutting, speed up the cutting process, and increase the cutting depth3. DURABLE AND STABLE: DC air pump after long term testing and verification, function and stability is extremely reliable, can maintain stable airflow output even after a long time of work4. LOW NOISE AND VIBRATION: Upgraded silent design, air assist pump internal structure and external damping feet significantly reduce noise or vibration, does not affect the laser cutting accuracy, providing a quiet working environment below 40dB5. EASY TO INSTALL AND COMPATIBLE: No need to install air pump, adjustable flow with regulator(not included).
