ARC series air reverse circulation drilling rig is a new, efficient and environmentally friendly geological drilling equipment. It uses the latest air reverse circulation drilling technology from Master Research Institute, compressed air is used as the circulating medium to quickly discharge，the cuttings from the bottom of the hole through reverse circulation. Rock cuttings and dust are effectively collected and sorted through dust collectors，avoid sample contamination，ensure the accuracy of sample data. The drilling rig is mainly used in mineral exploration, hydrogeological exploration, engineering geological exploration and other fields, suitable for various geographical environments，including complex environments such as thin air at high altitudes, thick permafrost, and abundant groundwater. It is the preferred equipment for geological exploration drilling and other deep hole operations.
