CIR series DTH Hammer, a kind of valve equipped low air pressure hammer with a single piston, a plate valve and a central exhaust structure.

The compressed air is adopted as the driving force. To get a better performance and prevent dust pollution, some high-pressure water may be added into the air for wet rock drilling.

DTH Hammer Avoid the problem happens on foot valve. Fracture,expansion and contraction Lower air comsumption and higher impact frequency. 15-30% higher drilling efficiency than the bit with foot valve.
