Hunst 160W Air Compressor Electrical Magnetic Air Pump 110V/220V ACO-009E, for CO2 Laser Engraving Cutting Machine. Uv Laser Marking Machine This kind of glasses mainlyFeatures: 1: The case is made of high quality ZL 102 aluminum alloy with streamlinedesign, heat dissipation is more effective. 2: Driven by electrical magnetic motor,adopt straight line reciprocal,motion toproduce air and more reasonable in structure. 3: Adopt SF3 new type wearable material for the cylinder and piston,which isof low power consumption,large air output and high air pressure. 4: Non oil lubricating design, the compressed air is purified.
