Overview

A diesel-powered air compressor uses a diesel engine to drive a compressor element and produce pressurised air. It is suited to remote mine and quarry sites where electrical power is limited or unavailable. The compressed air can power pneumatic rock drills, breakers and other air-driven tools.

Main components

Diesel engine; compressor air-end; intake filter; cooling system; air/oil separator where fitted; control panel and pressure gauges; air outlet connections; protective enclosure or trailer frame.

How it works

The engine turns the compressor element, which draws in ambient air and compresses it. The unit cools and conditions the compressed air before delivering it through hoses to connected equipment.

Typical applications

Pneumatic drilling, rock breaking, construction, quarrying, mine development and general compressed-air supply.

Selection considerations

Choose by required airflow and working pressure, altitude, ambient temperature, duty cycle, fuel consumption, noise limits, service support and portability. Confirm the drill’s air-pressure and air-consumption requirements before selecting a compressor.

Safety considerations

Operate outdoors or with suitable exhaust extraction; keep hot surfaces and exhaust away from combustible materials; depressurise before servicing; inspect hoses and couplings; use hearing protection and follow the manufacturer’s maintenance schedule.
