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.
Operating at either 425 cfm at 100 psi or 375 cfm at 150 psi, the P425/HP375delivers 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 busy jobsites.
The P425/HP375 and HP450/VHP400 are powered by a Cummins QSB 4.5L Tier 4 Final-compliant engine. Emissions technology includes selective catalytic reduction (SCR) and diesel oxidation catalyst (DOC) after treatment, which is virtually maintenance-free. A 5-gallon diesel exhaust fluid (DEF) tank only has to be refilled once for every two diesel refuels. Doosan says this feature is especially important for rental companies where air compressors are used by many customers.
Both generators are equipped with a Doosan-designed and -manufactured air end that requires 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. In addition to better fuel economy the technology fosters significant noise reduction.
A redesigned control panel has been updated with a simplified digital display and LED backlit gauges. Drillers are able to select service intervals and quickly access machine diagnostics.
The exterior of the dual flow, dual pressure air compressors includes a 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 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.
