Competitive Advantage
•  Valveless air distribution, more reliable.
•  Simple design of the piston. Long life span.
•  More efficient energy transfer, faster drilling speed, low air consumption and lower oil consumption. 
•  Fewer internal parts, simple structure, less failure and easier to maintain.
•  Easy to disassembled because the top sub, the drive chuck and the external cylinder are connected by       multiple steps thread.
