The products 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 lubrication and pure 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 streamline design and heat-dissipation is more effective.
