The Characteristics of High Air Pressure DTH Hammers Without Foot Valve:


It is a kind of high air pressure DTH hammer without foot valve, and it is our newest design. It is also one of the most advanced DTH hammers in the world.


High Air Pressure DTH Hammers Without Foot Valve 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 span, easy and cheap maintenance.

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


DHD and COP Series DTH Hammers Features:


1. Valveless air distribution, more reliable.

2. The simple design of the piston. Long life span.

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

4. Fewer internal parts, simple structure, long life span, less failure and easier to maintain because all the parts are heat treated.

5. Easy to disassemble because the top sub, the drive chuck, and the external cylinder are connected by multiple steps thread.


DHD / COP Series DTH Hammers Advantages:


1. Simple and reasonable design, easy to assemble and dis-assemble, low problem rate.
2. Low air consumption, smooth drilling, maximum impact power, high penetration rate.
3. Multiple precise heat-treatment with all hammer parts to provide long lifespan under roughest working conditions.
