20 m³/min 13 bar Portable Diesel Air Compressor for Mining & Borehole Drilling

The PRMD-2013 is optimized for water well drilling in the 200–500 meter depth range using 6–8 inch DTH hammers. At these depths, the 13 bar pressure maintains consistent hammer impact efficiency even with 50+ meter hose runs and typical pressure losses. For wells deeper than 500–600 meters, consider upgrading to our 22 m³/min 20 bar model or 34 m³/min 25 bar model to ensure adequate pressure at depth. Performance factors affecting maximum depth include rock hardness, hose length and diameter, and operating altitude.

The PRMD-2013 maintains approximately 12.5–13.0 bar output at altitudes up to 4,000 meters thanks to its turbocharged Cummins QSC8.3 engine with wastegate boost control. In contrast, most 12 bar competitors experience 15–20% pressure loss at similar altitudes, dropping to 10–10.5 bar effective pressure. In our Peru mining case study at 3,850m altitude, the PRMD-2013 delivered consistent 12.8 bar at the drill point while a competitor’s 12 bar unit could only manage 9.5 bar. This translates to 20–30% faster drilling speed and extended DTH hammer service life. Proven deployment altitudes include Peru (3,850m), Chile (4,200m), and Tibet (4,500m).

At full load, the PRMD-2013 consumes approximately 18–22 liters per hour of diesel fuel (roughly 0.9–1.1 L per m³ of compressed air). This is 25–35% more fuel-efficient than comparable Atlas Copco XAHS186 (24–26 L/h) and Sullair 185H (25–28 L/h) models. The efficiency advantage comes from the optimized Cummins QSC8.3 engine and advanced screw air end design. In typical mining operations running 3,600 hours annually, this saves approximately $4,000–$5,000 USD per year in fuel costs compared to competitors. The 380-liter fuel tank provides 17–21 hours of continuous operation between refueling.

The 20 m³/min airflow can support one 6–8 inch DTH hammer operating at full capacity, or two smaller 4–6 inch hammers running simultaneously. For multiple large tools or continuous multi-tool operations (for example, three pneumatic breakers plus site ventilation), consider the 27 m³/min 12 bar model which provides greater airflow capacity. The PRMD-2013 is optimized for single high-performance tool applications where both pressure (13 bar) and flow (20 m³/min) are critical—such as medium-depth water well drilling or mining blast hole operations.

Standard maintenance schedule: Engine oil change every 250 hours, air and fuel filters every 500 hours, compressor lubricant change every 1,000 hours, and oil separator element every 2,000 hours. In high-dust environments (mining, quarrying), reduce air filter service to every 25–50 hours. The PRMD-2013 uses standardized Cummins engine parts and SKF bearings, both globally available with fast delivery in over 190 countries. Unlike some competitors with proprietary parts, Cummins service centers exist in virtually every mining region worldwide, ensuring minimal downtime. Average annual parts cost is approximately 30–40% lower than Atlas Copco or Sullair equivalents.

Yes, the PRMD-2013 is well-suited for pipeline pressure testing applications. It delivers a stable 13 bar output, meeting ASME B31.4 and B31.8 standards for hydrostatic test alternatives (typically 1.5x operating pressure). The compressor can effectively test pipelines from DN200 to DN600 (8 to 24 inches) diameter. The 20 m³/min high airflow reduces test time significantly compared to smaller compressors—for example, pressurizing a 10 km section of DN400 pipeline takes approximately 3–4 hours versus 6–8 hours with a 12 m³/min unit. For lower-pressure pipeline work below 10 bar, the 12 m³/min 7 bar model offers better fuel efficiency.
