Product Description
OEM Fully Hydraulic Air Rotary Drill Rig 400m Underground Drilling Depth
Reliability meets performance in the OEM Fully Hydraulic Air. Its dual-circuit hydraulic system provides independent control of rotation and feed, enabling precise drilling in complex geological structures. The oversized cooling system prevents overheating during extended runs, while the corrosion-resistant components extend service life in harsh environments.
Product Overview
The ST 400 Air Rotary Drill Rig Machine is designed for water well drilling, agricultural irrigation wells, geothermal air conditioning holes, and other well applications. It is particularly effective for water intake projects in mountainous areas and rock formations, delivering efficiency up to ten times higher than traditional rotary drilling rigs.
