Large Portable Air Compressors 8.6-12 bar
A choice
of 6 models provide large volumes of air ranging from 21 to 28.3m3/min.
at 8.6,10 or 12 bar g pressures for factory standby air, blast cleaning
of large structures and to support drilling operations in surface
mining, civil engineering and ground exploration projects in the
most demanding of sites and extremes
of altitude and climate.
All models are powered by the proven Cummins 6 cylinder M11 turbo charged diesel engine meeting the EC Level 1 emission standards.
CNC machining of precision components plus state of the art sheet metal and electrostatic painting equipment, supported by the rigorous production systems required for ISO 9001 certification provide the highest standard of quality and reliability.
A world wide network of CompAir sales and service facilities are well experienced in the needs and priorities of site operations in remote areas and trained to deal with them promptly and efficiently.
Features
Supply on demand control system regulates engine speed and compressor air intake valve to match closely varying air demand so that fuel efficiency is optimised.
Illuminated control panel with lockable door and shatterproof window.
All necessary instrumentation, including gauges for air delivery pressure and temperature, tachometer, hour meter, and auto shutdown fault indicators.
A warm up wheel valve enables engine to be run on a low compressor load on start up for additional durability.
2 stage air inlet filters for engine and compressor with safety elements to provide added protection in case of maintenance neglect or very high dust levels.
Air filter service indicators, prominently positioned on instrument panel, warn when filter maintenance is required, and thus also assist in avoiding premature replacement.
Large capacity 488 litre fuel tank with level gauge and inspection plates to enable tank cleaning.
Heavy gauge welded steel chassis construction for towing on difficult ground without distortion.
260mm ground clearance for easier positioning.
