High Air Pressure DTH Hammer

The characteristics of High air pressure DTH hammer without foot valve.

It is kind of high air pressure down the hole hammer,without foot valve,The drilling speed is higher than the hammer with foot valve.And more energy efficient.It is one of the most advanced DTHhammers in the word .

It has the following characteristics:
1.valveless air distribution,more reliable.
2.the piston has a simple design,long life.
3.Long service life and low failure rate.
4.Simple operation and easy to use.

The characteristics of High air pressure DTH hammer with foot valve.

It is kind of valveless high air pressure down the hole hammer,with foot valve,This hammer operation is more easily to use, It can reduce the failure caused by the operator’s oeration error.

It has the following characteristics:
1.Speed increase 15%~30% than the hammer with foot valve.
2.Bits without nylon tube,The problems caused by rupture of nylon
tube,expansin,sepansion  and shrinkage will be avoided.
3.Low gas consumption,energy saving 10%.
4.This hammer has simple strcture,good reliability and long service life.
