The new platform covers five large Doosan portable compressors, the 9/274, 9/304, 12/254, 17/244 and 21/224 models, offering free air deliveries from 21.5-30m³/minute at operating pressures from 8.6-21bar.
The compressors, powered by the Cummins QSL9 T4F six-cylinder diesel engine, meet the Stage IV regulations without the need for a DPF. In the new 12/254 compressor, for example, the QSL9 engine provides 247kW of power at a full load speed of 1,800rpm, and offfers a free air delivery of 25m³/minute at a discharge pressure of 12bar.
The new units are used to provide compressed air for a wide range of drilling and boring machines for quarrying, mining, site investigation, geothermal, mineral exploration and water well construction work.
