Peakroc® PRMD series diesel portable Screw Air Compressor are widely used in:

  • Water well & geothermal drilling (100–200 m)

  • Small and medium mining & quarry support

  • Pipeline pressure testing (gas/water networks)

  • Sandblasting & surface cleaning

  • Civil construction & tunneling

  • Agricultural & rural water supply projects

The Peakroc® PRMD-08510 is a portable diesel-driven screw air compressor delivering 8.5 m³/min at 10 bar working pressure((300cfm 145psi).). It is designed for field work where stable pressure, continuous operation, and mobility are essential—such as in water well drilling, small mining projects, pipeline pressure tests, and sandblasting work.

1. Robust Engine System & Structural Endurance

  • Powered by a heavy-duty industrial diesel engine matched precisely to compressor load.

  • Mounted on a vibration-damped chassis for improved stability on rugged terrain.

  • Enclosed within a 2 mm cold-rolled steel shell and flame-retardant sound insulation, providing durability, reduced noise, and operator safety.

2. High-Efficiency Air End with Precision Components

  • SAP-profile screw rotor ensures high compression efficiency at 10 bar pressure.

  • Rotors made from American alloy steel, supported by SKF bearings for extended lifespan.

  • Consistent output with minimal pressure drop, especially for demanding pneumatic drilling systems.

3. Clean Air System & Easy Maintenance

  • Dual-stage air filtration removes up to 99.9% of dust, extending rotor and engine life in dusty drilling environments.

  • High-efficiency oil separator ensures clean compressed air and low oil carryover.

  • Maintenance-friendly layout: all service ports are accessible from one side.
