Features: 1Air Assist Pump: The air assisted pump uses air to reduce the surface temperature of the cut object to avoid distortion and discoloration caused by high laser temperature. 2Cut Faster and Deeper: Air assisted pumps blow away smoke, residue and debris generated during the engraver's work, keeping the laser focused on cutting, speeding up the cutting process and increasing the depth of cut. 3High Stability: The air assisted pump is extremely reliable in function and stability, maintaining a steady airflow output even after long hours of work. 4Low Noise: Both the internal structure of the air assisted pump and the external vibration damping feet significantly reduce noise or vibration without affecting laser cutting accuracy, providing a quiet working environment of less than 40 decibels. 5Easy to Install: The air assisted pump can be used with a DC12V regulator (not included) to adjust the flow rate and is compatible with most laser engraving machines on the market.
