3. A good performance in central air exhaust and cuttings discharge, which reduces the repeated crushing of rock;

4.A check valve device is available to drill holes finder water.

High air pressure DTH drilling rig, 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 a multi-step thread.
