Doosan Portable Power has expanded its lineup of dual pressure and dual flow air compressors with the introduction of the Tier 4 Final–compliant P425/HP375 and HP450/VHP400 air compressors.
Both models deliver the pressure and flow options typical of two units in a single air compressor, allowing the operator to change from a low-pressure to a high-pressure setting with one machine. The P425/HP375 delivers 425 cfm at 100 psi or 375 cfm at 150 psi. The HP450/VHP400 operates at 450 cfm at 150 psi or 400 cfm at 200 psi, respectively. The variable settings are suited to a wide range of applications, including general construction, abrasive blasting and structural steel spray painting.
Both models provide a cost-effective, portable air compressor with added versatility and productivity that is a real value on any jobsite and the perfect complement to any rental fleet. Both models share the same small package design, a decrease in size for the HP450/VHP400. The compact footprint allows for easy transport and greater maneuverability within the often tight confines of a busy jobsite.
The P425/HP375 and HP450/VHP400 are powered by a Cummins QSB 4.5L Tier 4 Final–compliant engine with selective catalytic reduction (SCR) and diesel oxidation catalyst (DOC) aftertreatment. A 5-gallon diesel exhaust fluid (DEF) tank has to be refilled only once for every two diesel refuels. This is especially important for rental companies where air compressors are used by many customers.
The P425/HP375 and HP450/VHP400 are equipped with a Doosan-designed and -manufactured airend. A highly efficient rotor profile requires less horsepower to deliver high-volume cfm output, resulting in low fuel consumption.
Fuel economy is also achieved through an electronically controlled engine-driven cooling fan with a hydraulic clutch that engages only when required by higher operating temperatures. The result is reduced fuel consumption and significant noise reduction.
A redesigned control panel with a simplified digital display and LED backlit gauges improves overall operation of the P425/HP375 and HP450/VHP400 air compressors. The operator is able to select service intervals and quickly access easy-to-understand machine diagnostics.
The P425/HP375 and HP450/VHP400 are backed by a 1-year/2,000-hour bumper-to-bumper warranty and a 2-year/4,000-hour engine warranty. A 5-year/10,000-hour powertrain extended warranty is also available.
