Doosan launch new large Stage IV-compliant compressors

Doosan 12/254 compressor

South Korean manufacturer introduces new five-model portable compressor range

DOOSAN Portable Power have launched a new range of large Stage IV-compliant portable compressors which are the first to feature the company’s air-end. The latest 9/274, 9/304, 12/254, 17/244 and 21/224 models provide free air deliveries between 21.5 and 30 cubic metres per min and operating pressures between 8.6 and 21 bar.

The new Stage IV compressors build on the high standards established by the Stage IIIB models, combining compact size and easy serviceability to deliver a good return on investment for customers.


All the new compressors are powered by a Cummins QSL9 T4F six-cylinder diesel engine which meets Stage IV regulations without the need for a DPF.  The 12/254 compressor (pictured) provides 247kW (331hp) at 1,800 rev/min and a free air delivery of 25 cubic metres per min at a discharge pressure of 12 bar.

All the new Doosan large compressor models have been designed to provide compressed air for a wide range of drilling and boring machines used in quarrying, mining, site investigation, geothermal and mineral exploration. They also cover specialist applications including abrasive blasting, spray painting and delivery of standby/temporary compressed air.

With a length (drawbar up/drawbar down) of 4,408/5,841mm, a width of 2,120mm and height of 2,497mm, the compressors provide a compact size that offers a number of advantages for truck-mounted configurations.

The Stage IV compressors are available with a wagon wheel-style running gear system as standard, but the customer has the option of either a new fast-tow option, which allows the units to be towed on public roads, or the ‘no wheels’ chassis option, where the machines are supplied in a permanent-mount configuration.

The highly modular design of the Doosan compressors offers the flexibility for a wide range of optional equipment to be added. These include: the fitting of an aftercooler with water separator; additional filters (IQ-system); and the use of a paint scheme to match the customer’s livery.
