Doosan Portable Power Expands Dual Pressure/Dual Flow Line

Doosan Portable Power has added to its dual pressure/dual flow air compressor line with the Tier 4 Final P425/HP375 and HP450/VHP400.

doosan dual flow pressure compressorOperating at either 425 cfm at 100 psi or 375 cfm at 150 psi, the P425/HP375 delivers the pressure and flow options typical of two units in a single air compressor. The variable settings are suited to a wide range of applications, including general construction, abrasive blasting and structural steel spray painting.

The HP450/VHP400 operates at 450 cfm at 150 psi or 400 cfm at 200 psi, allowing the operator to change from a low-pressure to a high-pressure setting with one machine. The HP450/VHP400 has also been redesigned within a smaller footprint for ease of transport and greater maneuverability.

Powered by a Cummins QSB 4.5L Tier 4 Final–compliant engine, emissions technology includes selective catalytic reduction (SCR) and diesel oxidation catalyst (DOC) aftertreatment, which is virtually maintenance-free. A 5-gallon diesel exhaust fluid (DEF) tank has to be refilled once for every two diesel refuels. 

The new models are equipped with a Doosan-designed and  manufactured airend that offers an efficient rotor profile, requiring less horsepower to deliver high-volume cfm output. The result is improved fuel economy. An electronically controlled engine-driven cooling fan with a hydraulic clutch that engages only when required by higher operating temperatures, helping improve fuel economy and reducing noise. 

A redesigned control panel with a simplified digital display and LED backlit gauges improves overall operation of the air compressors. The operator is able to select service intervals and quickly access easy-to-understand machine diagnostics.

The exterior includes a galvannealed steel enclosure that prevents rust and corrosion, lockable access doors and an A-frame drawbar for increased towing stability. The units also include a toolbox for quick, convenient storage. Both have a one-year/2,000-hour bumper-to-bumper warranty and a two-year/4,000-hour engine warranty. A five-year/10,000-hour powertrain extended warranty is also available.
