45 m³/min 10 bar Portable Diesel Air Compressor for Mining Tunneling

The Peakroc® PRMD-4510 delivers a free air delivery of 45 m³/min at 10 bar (1600 cfm / 145 psi), making it one of the most powerful mobile screw compressors in its class. Designed for large-scale mining, open-pit drilling, tunnel excavation, pipeline purging, and multi-rig operations, it offers high airflow, reliable power, fuel efficiency, and excellent durability in extreme field environments. Powered by a heavy-duty Cummins diesel engine and a high-capacity screw air end, it ensures continuous and stable air supply for the most demanding industrial and construction applications.

High-Volume Air Supply for Multi-Tool Operations

With an output of 45 m³/min at 10 bar, this unit is capable of driving multiple DTH hammers, pneumatic drills or sandblasting systems simultaneously. It is ideal for large-scale mining and infrastructure projects requiring uninterrupted high-volume airflow.

Reliable Diesel Engine and Reinforced Chassis

Powered by a high-torque Cummins turbocharged diesel engine, the PRMD-4510 ensures strong power performance and low fuel consumption. The compressor is built on a heavy-duty, vibration-damped chassis with a 2 mm cold-rolled steel enclosure for enhanced durability on rugged terrain.

High-Efficiency Screw Air End

Equipped with a large-displacement screw air end featuring advanced SAP rotor profiles, American alloy steel rotors and SKF bearings, the unit provides superior compression efficiency, long service life, and stable performance during continuous operation.

Advanced Cooling and Filtration System

A dual-stage air filtration system removes 99.9% of dust and impurities to protect the air end and engine. The high-capacity oil separator, oversized radiator, and optimized air cooling paths ensure stable operation in hot climates, high altitudes, and dusty mining sites.
