Product Description
High Air Pressure DTH Hammer Without Foot Valve

The DTH hammer is also called pneumatic drill hammer. It is the power machine on the hole bottom that takes compressed air as the dynamic medium and uses the energy of compressed air to generate a continuous impact load. The compressed air can also be used as washing medium. It is mainly used in hydrological well drilling, core-free geological drilling, geological disaster prevention engineering and mine drilling. It is applicable for gravel and hard rock, it can also be used in soft soil when equipped with special structure drill bit.

Advantages

* No foot valve needed, thus saving the trouble of foot valve fracture, expansion and contraction.

* Lower energy consumption and higher impact frequency. The drilling speed is 15%-30% higher than that of the same type with foot valve.

* Simple structure, reliable parts, long service life, easy maintenance and low cost.

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