Operating 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 versatility is ideal for cable laying, pipeline testing and operating pneumatic tools.
The HP450/VHP400 has also been redesigned within a smaller footprint, matching the same compact size of the P425/HP375. The smaller package allows for ease of transport and greater maneuverability within the often tight confines of a busy jobsite.
Both models provide a cost-effective, portable air compressor with quality engineering, versatility and productivity that is a real value on any jobsite and the perfect complement to any rental fleet.
Powered by a Cummins QSB 4.5L Tier 4 Final–compliant engine, the P425/HP375 and HP450/VHP400 offer the same great performance and reliability expected from Doosan Portable Power air compressors. 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 only has to be refilled 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 that offers a highly efficient rotor profile, requiring less horsepower to deliver high-volume cfm output. The result is improved fuel economy.
Lower fuel consumption is also achieved with the installation of an electronically controlled engine-driven cooling fan with a hydraulic clutch that engages only when required by higher operating temperatures. The innovative technology leads to better fuel economy and significant noise reduction.
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 of the P425/HP375 and HP450/VHP400 includes a galvannealed steel enclosure that prevents rust and corrosion, lockable access doors for increased security and an A-frame drawbar for increased towing stability. The units also include a toolbox for quick, convenient storage.
The P425/HP375 and HP450/VHP400 are backed by 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.
