High Air Pressure DTH Hammer without foot valve

Advantages:
1. Avoid the trouble caused by the foot valve's fracture, expansion and contraction.
2. Lower energy consumption and higher impact frequency, 15%-30% quicker drill speed than same hammer with foot valve.
3. Simple design of the piston, long life.
4. More efficient energy transfer, faster drilling speed, low air consumption and lower oil consumption.
5. Fewer internal parts, simple structure, longer life,less failure and easier to maintain because all the parts are heat treated.
6. Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-sted thread.
