The Product adopts an electric magnetic motor, and the air is produced by the piston in the way of straight-line and reciprocal motion, and it has a more reasonable structure. Non-oil lubricating design to produce purer compressed air. Adopt SF1 new-type wearing-resistant material for the piston and cylinder, which is of low power consumption, large air output and high air pressure. The case is made of high-quality ZL102 aluminum alloy with streamlined design, and heat-dissipation is more effective. Phosphorize disposition, regular coloring, and adhesive strength.
