    Compressed air at the same time can also doubles as a wash hole medium. Pneumatic impactor has high wind pressure and low wind pressure, valve type and no valve type of points. Usually the pneumatic impactor directly connected with the carbide rod tooth drill to impact the way rock, low-speed rotation is not coring the full drilling. Mainly used in hydrological wells drilling, non core geological drilling, geological disaster prevention and control projects and mine drilling and other fields. Suitable for use in gravel and hard rock formations, specially configured drill bits can also be used in soft soil. Mechanical drilling speed is generally much higher than the hydraulic impactor drilling, but need to be equipped with a larger capacity of the air compressor, fuel consumption, noise, dust pollution. Drilling depth by the groundwater level, the greater the impact of water.
