A4 Air Assist with a 30L/Min Air Pump

Efficient and Cleaner EngravingBlowing out 30 liters of gas per minute, the Mecpow A4 air pump is able to puff away the hot smoke and powder, effectively lowering the surface temperature of the engraved object, which avoids the distortion and discoloration caused by high temperatures and ensures smooth lines, complete patterns, as well as clean material surfaces.  Longer Service TimeThe air assist can reduce the damage from the high temperature and the hot smoke. The air pump protects the laser lens, blows away the dust on the laser lens and prevents other residues from entering the beam diameter. The rubber feet prevent the air pump from moving, reducing wear and tear on the air pump as well as ensuring a longer lifespan.  Adjustable Air Volume The knob design achieves precise adjustment of airflow during work. With the rotary knob, you can adjust the air volume exactly as required with ease. The humanized design creates a stunning engraving experience. Low Noise and Stable Working Ti
