Kaishan LGCY Two-Stage Diesel Screw Air Compressor (15–35 Bar)

• Deep Water Well Drilling: 25–35 Bar models (25–35 m³/min) supply sufficient volume and pressure to overcome hydrostatic water head resistance in 300m–600m deep wells (pairs perfectly with Kaishan KW300, KW450, and KW600C rigs).
• Open-Pit Mining & Quarry Blasting: 17–21 Bar models (18–27 m³/min) drive 4" to 8" DTH hammers on crawler rigs (such as Kaishan KG510 and KG9) for high-speed bench blast hole drilling.
• Pipeline Pressure Testing: 25–35 Bar ultra-high pressure units deliver rapid pressurization for gas pipelines, pressure vessels, and long-distance transmission lines.

Q: Why is two-stage screw compression preferred for deep borehole drilling?

A: Deep holes over 200–600 meters encounter heavy hydrostatic water head resistance and deep back-pressure. Two-stage compression maintains high air delivery at 20–35 bar with 15%–20% lower diesel fuel consumption than single-stage units, ensuring fast cuttings lift and preventing downhole tool jamming.

Q: How does the chassis handle rough mining and off-road towing?

A: LGCY compressors are built on heavy-duty channel steel chassis equipped with torsion-bar or multi-leaf spring suspension, heavy off-road pneumatic tires, mechanical/air brakes, and an overhead single-point crane lifting bail for secure jobsite positioning.
