Useful for applications where users already have a generator on site or have grid power available, Doosan Portable Power’s HP750e portable air compressor features a quiet three-phase electric motor instead of a diesel engine. Launched at CONEXPO-CON/AGG 2011, the 750-cfm unit is 100-percent emissions free and therefore not subject to EPA emissions regulations. Power and cooling systems are controlled by a liquid cooled variable frequency drive system. The electric-driven model eliminates the need to purchase, store and transport diesel fuel, and has easily accessible major service points for simplified maintenance. The HP750e’s intuitive full color digital display has a dual colored LED backlighting system to ensure operator visibility, and an easy-to-use interface can be remotely monitored via wireless connection with a smartphone, tablet or personal computer. A heavy duty tandem axle running gear has an extended life slipper spring system for protection during highway towing.

The 1750RT and 2100RT have Yanmar Tier III naturally aspirated and turbocharged diesel engines, respectively, that deliver 68.4 horsepower and 179 foot-pounds of torque on the 1750RT and 70.7 horsepower and 206 foot-pounds of torque on the 2100RT.
