High Air Pressure DTH Hammer
1. Lower energy consumption
2. Higher impact frequency
3. Easy and cheap maintenance
4. Long life, reliable
Faster Drilling Speed and Most Advanced Air DTH Hammer:
1.10 years manufacturing experience;
2. Certificate: ISO9001: 2008
3. Material: Carbide
It is a kind of valveless high air pressure DTH Hammer with foot valve.
It has the following advantages:
1. Valveless air distribution. More reliable.
2. Simple design of the piston, 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 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 multi-step thread.
Our advantages:
