High Air Pressure DTH Hammer(with foot valve)

It is a kind of valveless high air pressure DTH hammer with foot valve.

 

Advantages:

1.Valveless air distribution, more reliable;

2.Piston with simple but compact design, long life;

3.More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption.

4.Fewer internal parts, simple structure, longer life, less failure and easier to maintain, with the all heat treated parts;

5.Easy to disassemble, thanks for the top sub, drive chuck and external cylinder all are connected by multi-step thread.

High Air Pressure DTH Hammer(without food valve) 

It's a king of high air pressure DTH hammer without footvalve,our newest design. it's also one of the most advanced DTH hammer in the world.

 

Advantages

1.Out of the trouble of foot valve fracture and expansion and contraction;

2.Lower energy consumption and higher impact frequency. The drilling speed is 15-30% higher than the one with foot valve;

3.Simple structure, reliable parts, long life, easy and cheap maintenance;

4.Lower air and oil consumption, the oil consumption is about 10% lower than the one with foot valve.

According to your request, the top sub can be made into two spanners, an air controlling hole can be drilled on the check valve to provide more efficient cuttings discharge.
