PeakRoc® 21 m³/min 14 bar compressor is ideal for high-pressure and high-air-demand applications, including:

Water Well Drilling (≥200m depth) – Provides stable 14 bar high-pressure air for DTH hammer drilling.
Mining & Quarry Blasting – Supports pneumatic rock drills, DTH hammers, and blasting operations.
Pipeline Pressure Testing – Suitable for hydrostatic and pneumatic pressure tests in oil & gas pipelines.
Sandblasting & Surface Cleaning – High flow and pressure ensure continuous abrasive blasting performance.
Geothermal & Foundation Drilling – Reliable power source for multi-hole ground drilling projects.

The PeakRoc® PRMD-2114 portable diesel screw air compressor provides a free air delivery of 21 m³/min at 14 bar (750 cfm / 203 psi), making it ideal for high-pressure pneumatic applications such as down-the-hole (DTH) drilling, deep water well projects, and heavy-duty mining operations. Powered by an industrial-grade diesel engine, this unit ensures consistent airflow, fuel efficiency, and stable performance in remote or off-grid job sites.

1. Heavy-Duty Power & Structural Reliability

Equipped with a fuel-efficient diesel engine built for continuous operation.
Reinforced chassis with vibration-damping and off-road towing capability.
2–3 mm cold-rolled steel canopy with sound insulation and flame-retardant materials.

2. High-Efficiency Air End & Core Components

Large-displacement screw air end with optimized rotor profile for high-pressure output.
Rotors made from American alloy steel with SKF heavy-duty bearings.
Ensures high compression efficiency, stable airflow, and long operational life.

3. Clean Filtration & Easy Maintenance

Dual-stage air filtration removes up to 99.9% of dust and particulate.
High-performance oil separation ensures low residual oil content (<3 ppm).
Side-opening doors allow easy service access for filters, belts, and fluid drainage.
