The Product adopts electric magnetic Motor, and the air is produced by piston in the way of straight-line and reciprocal motion, and it has 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 flow power consumption, large air output and high air pressure. The case is made of high-quality ZL102 aluminium alloy with streamline design, and heat-dissipation is more effective. Phosphorize disposition, regular colouring and adhesive strength.
