The 12/254 compressor has a free air delivery of 25 m³/min (883 cfm) at a discharge pressure of 12 bar (175 psig). This model is part of a new family of five large Doosan portable compressors that also includes the new 9/274, 9/304, 17/244 and 21/224 models and offers free air deliveries from 21.5 to 30.0 m3/min at operating pressures from 8.6 to 21.0 bar.
The new Stage IV compressors build on the high standards established by the Stage IIIB models, again combining compact size and easy serviceability to ensure a fantastic return on investment. All the new compressors are powered by the Cummins QSL9 T4F 6-cylinder diesel engine which meets the Stage IV regulations without the need for a DPF. In the new 12/254 compressor, the QSL9 engine provides 247 kW (331 HP) of power at a full load speed of 1800 rpm.
