Dual-pressure air compressor

The Doosan P425/HP375 dual-pressure/dual-flow air compressor delivers the pressure and flow options typical of two units in a single air compressor.

Operating at either 425 cfm at 100 psi or 375 cfm at 150 psi, the variable settings are suited to a wide range of applications, including general construction, abrasive blasting and structural steel spray painting.

Powered by a Cummins QSB 4.5L Tier 4 Final–compliant engine, the P425/HP375 offers 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 five-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 is equipped with a Doosan-designed and -manufactured air end 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 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 unit also includes a toolbox for quick, convenient storage.
