Doosan Portable Power Electric-Driven VP900e Air Compressor

December 11, 2013

Electric-driven VP900e portable air compressor replaces the typical diesel engine on the air compressor with three onboard electric motors that are controlled by a variable frequency drive (VFD) system—one airend motor and two cooling fan motors— each sized specifically for their dedicated function.

Variable frequency drive is the core of the electric air compressor system. It monitors the needs of the compressor by changing performance of the motors to provide exact power requirements, preventing the use of unnecessary power, the company says. During operation, the VFD automatically adjusts to the load demand, maximizing flow for each pressure setting. The operator has the capability to set the pressure at any level from 90 to 150 psi.
