4. High efficiencey working with air compressor
General Description of Drilling Rig

DFQ-200W is a portable type small borehole drilling machine with light weight, high efficiency
and multi-function, widely used for water well drilling, geothermal air-conditioning project and 
other boreholes, especially applicable to mountain area and rock formation water engineering. 



1. Drill up to 200m depth with 105mm borehole diameter
2. Diameter from 105-203mm

3. DTH hammer rotary drilling, fast speed in drill through hard rock areas;

4. Trailer type,easy pulled or dragged;

5. Both can work with mud pump and air compressor. But high efficiency with air compressor 
on hard formation
