Product Description
Drilling Deep Water Wells Air Drilling Rig With Multiple Specifications
Product Overview

The ST-350 Pneumatic Drilling Rig is engineered to deliver consistent, high-speed drilling capability across diverse geological conditions. Its advanced hydraulic architecture provides smooth operation while the high-capacity air system ensures deep penetration in hard rock formations. Contractors value its fast setup time and minimal maintenance requirements.

This medium hydraulic/electric rig for 50-350m wells suits town water supply, small-industry use, and mine auxiliary needs. With 50-120kW power, it drills 15-50m daily, handling sand, gravel, and moderately weathered rock. Features include intelligent monitoring, safety protection, easy maintenance, and operation in temperatures from -20℃ to 45℃.
