Feature: 1. Smoother Cut Edge: Use air to quickly reduce the surface temperature of the object to be cut to avoid deformation and discoloration as well as blowing away the residue to ensure that the surface and the cutting edge are smooth. 2. Efficient Cutting: When working with high speed strong air flow to blow away the smoke, residue and debris generated during the working process of the engraving machine, keep the laser focused on cutting, speed up the cutting process and increase the cutting depth. 3. Working Stability: The laser cutter air assist pump can also maintain stable airflow output after a long time of operation. 4. Little Work Noise: The internal structure and external damping feet significantly reduce noise or vibration, do not affect the laser cutting accuracy, and provide a quiet working environment of less than 40 dB. 5. Good Compatibility: Comes with wide compatibility, the light weight and compact air assist is very convenient to install on your laser engraver.
