The Peakroc® 39 m³/min 25 bar portable diesel air compressor is designed for:

Deep Water Well & Geothermal Drilling (300–700m)
High-Pressure DTH Drilling in Mines and Quarries
Oilfield Gas Lift, Foam Drilling & Well Servicing
Pipeline Hydrostatic & Pneumatic Pressure Testing
Hydropower, Tunnel Construction & Blasting Projects
Industrial Sandblasting & Surface Preparation

The Peakroc® PRMD-3925 delivers a free air delivery of 39 m³/min at 25 bar (1375 cfm / 363 psi), engineered for deep well drilling, geothermal projects, high-pressure DTH drilling, oilfield operations, and pipeline pressure testing. Equipped with a heavy-duty Cummins diesel engine and a high-pressure screw air end, this compressor provides strong airflow, stable high pressure, fuel efficiency, and outstanding durability in harsh field environments.

High-Pressure and High-Volume Air Supply

With 39 m³/min airflow and 25 bar pressure, this compressor is ideal for deep borehole drilling, reverse circulation drilling, and high-pressure applications such as oilfield gas lift and pipeline hydrostatic testing. It delivers consistent pressure for continuous heavy-duty operation.

Reliable Diesel Powertrain and Rugged Structure

The compressor is powered by a turbocharged Cummins diesel engine, providing high torque output, strong power, and fuel efficiency. The reinforced chassis and 2 mm thick sound-proof steel enclosure offer resistance to vibration, harsh terrain, and extreme working environments.

High-Efficiency Screw Air End for 25 Bar Operation

Built with an advanced SAP rotor profile and alloy steel rotors, the screw air end is designed for high-pressure performance. SKF bearings and precision machining ensure reduced leakage, high compression efficiency, and longer service life.

Advanced Cooling and Filtration System

A dual-stage air filtration system removes up to 99.9% of dust and impurities, protecting the air end and diesel engine. A large-capacity oil separator, high-efficiency radiator, and optimized air cooling pathway maintain stable performance in hot, dusty, or high-altitude sites.
