Mecpow A4 Air Assist Pump - 30L/min, Adjustable Button Design, Long Service Life, Low Noise

The Mecpow A4 Air Assist Pump delivers 30 liters of air per minute, effectively blowing away hot smoke and powder to lower surface temperatures during engraving. This prevents warping and discoloration, ensuring smooth lines and complete patterns with clean material surfaces. With a long service life, this pump assists in temperature control, protects the laser lens by blowing away dust, and prevents other residues from entering the beam diameter. Its adjustable air flow design via a rotatable button allows precise control during work, and its humanized design creates a comfortable engraving experience.
