PeakRoc® 21 m³/min 10 bar compressor is ideal for high-pressure and high-air-demand applications, including:

Water Well Drilling – Air flushing for 200–350 m drilling rigs
Mining & Quarrying – Powering DTH hammers and drilling equipment
Construction & Tunneling – Shotcrete, rock bolting, air tools
Sandblasting & Surface Preparation – Continuous air feed to blasting machines
Pipeline Pressure Testing – Drying and pressure inspections
Oil & Gas / Geothermal Drilling –Auxiliary compressed air supply

The Peakroc® PRMD-2110 delivers a continuous airflow of 21 m³/min at 10 bar (750cfm 145psi), making it a suitable power source for demanding applications such as water well drilling, blast-hole drilling, mining operations, sandblasting, and pipeline pressure testing. It is equipped with a fuel-efficient Cummins diesel engine and a heavy-duty screw air end to ensure stable performance, even in remote or harsh working environments.

The chassis is engineered for off-road transport, featuring reinforced steel structure and dual-axle design for improved stability. The enclosure is built with 2 mm cold-rolled steel panels and flame-retardant sound-insulated materials to reduce noise and withstand outdoor operation.

1. Reliable Power & Enhanced Structure

Powered by a Cummins diesel engine with direct fuel injection for stable torque output.
Heavy-duty trailer chassis with dual wheels, damping components, and reinforced frame.
2 mm cold-rolled steel canopy with fire-retardant and sound-proof insulation.

2. High-Efficiency Air End & Core Components

Screw compressor with optimized rotor profile for high compression efficiency.
Alloy steel rotors and Sweden SKF bearings ensure long operational life.
Built-in temperature and pressure protection for safe continuous operation.

3. Clean Filtration & Field Flexibility

Two-stage air filtration captures >99.9% of airborne dust.
High-capacity oil separation minimizes oil carry-over and protects internal parts.
Suitable for trailer-mounted or skid-mounted configurations for drilling rigs, mining platforms, and job sites without electric power.
