The case is made of high-quality ZL 102 aluminum alloy with
 
 streamline design,heat-dissipation is more effective.
 
 Driven by electrical magnetic motor,adopt straight-line reciprocal 
 
  motion to produce air and more reasonable in structure.
 
 Adopt SF3 new type wearable material for the cylinder and piston, 
 
  which is of low power consumption,large air output and high 
 
 air pressure.
 
 Non-oil lubricating design, the compressed air is purified.
