The KT7C high air-pressure down the hole drill rig for open use is an advanced drilling device integrating a down the hole drilling system and screw air compression system. Featuring a compact structure typical in our products, the rig has excellent integrity and mobility. It is equipped with a single-stage high air-pressure screw hose and the flow is 13 cubic meters per minute and pressure is 1.7MPa, thereby providing high-valued parameters. The drill rig provides strong power for the high air-pressure down the hole hammer and the drilling speed is higher than that of medium-air pressure drill rigs by 20%-50%. It is characterized by energy efficiency, safety, environmental-friendliness, flexibility, and simple operation. Equipped with a Yuchai China stage III engine, the drill rig meets national standards for emissions and environmental impact.
